Caterpillar 933
Maintenance schedule, common problems & OEM parts breakdown
The Cat 933 is a mid-size track-type (crawler) loader from Caterpillar's compact and mid-frame crawler loader range, built for site work, demolition, and confined-area material handling. This modern reissue of the 933 name ran from 1994 to 2003, carrying the 8FL serial prefix, and is powered by the Cat 3046 six-cylinder diesel rated around 70 hp (52 kW) SAE net. Operating weight runs roughly 8.5 to 8.7 tonnes (about 18,700 to 19,200 lb), varying with bucket type and undercarriage width. Drive runs through a torque-converter powershift transmission, planetary final drives, and steering clutches rather than a hydrostatic system. Caterpillar offered it in standard and low-ground-pressure (LGP) undercarriage widths, with general-purpose and multi-purpose bucket options.
Within this generation Caterpillar kept the torque-converter and steering-clutch driveline unchanged while trim, bucket, and undercarriage options shifted between standard and LGP builds. The line was then followed by the 933C and 933C Hystat, which moved to a single-joystick hydrostatic drive, a genuinely different transmission and steering system despite carrying the same model number. Caterpillar had also used the 933 name decades earlier, from 1954 to 1968, on an unrelated Traxcavator crawler loader with mechanical engines that was discontinued and succeeded by the 931 in 1972; buyers sourcing parts should confirm serial prefix and driveline before ordering, since torque converter, planetary final drive, and steering clutch parts on this 8FL-era 933 do not interchange with either the vintage Traxcavator or the later hydrostatic 933C. In the used and parts market this generation remains a working mid-size loader for demolition, scrap, and landfill sites, valued for a simpler mechanical driveline compared with its hydrostatic successors.

Model Identity & Generations
| This record (non-Hystat modern reissue) | Cat 933 track-type loader, non-Hystat modern reissue, produced roughly 1994-2003, serial prefix 8FL. Torque-converter powershift transmission, planetary final drives, and steering clutches — mechanically distinct from the related 933C / 933C Hystat (single-joystick hydrostatic drive, prefixes 4MS/5JS) sold alongside it. Engine, weight, dimension and bucket figures are shared across the 933 / 933C / 933C Hystat family per cross-referenced OEM literature; drivetrain, steering and braking details differ by variant and are described for THIS (non-Hystat, torque-converter) machine in the Transmission/Drivetrain group below. |
| CRITICAL - do not confuse with vintage 933 Traxcavator | Caterpillar used the 933 designation decades earlier for an unrelated crawler loader family (933, 933F, 933G) built roughly 1954-1968, powered by 4-cylinder D311/D320 engines at 50-60 flywheel hp, riding on D2/D4-sized undercarriage. That lineage was discontinued in 1968 and succeeded by the 931 in 1972. It has no engineering relationship to the modern 1994-2003 Cat 3046-powered 933 covered in this record. Do not blend vintage Traxcavator dimensions, engine or weight data into this modern machine's record. |
Engine
| Engine model | Cat 3046 diesel, four-stroke cycle, in-line 6-cylinder, direct injection, naturally aspirated. (Some third-party summaries mistakenly describe this engine as a 4-cylinder — factory specification literature and engine-parts cross-references confirm 6-cylinder.) |
| Bore x Stroke | 94 mm x 120 mm (3.7 in x 4.72 in) |
| Displacement | 5.0 L (305 in3) |
| Gross power (at 2400 rpm) | 57.4-58.2 kW (77-78 hp) — minor variance between the marketing cover page and the detailed spec table of the same document |
| Net/flywheel power (at 2400 rpm, by standard) | Caterpillar rating: 52.9 kW (71 hp). ISO 9249: 52.9 kW (71 hp). EEC 80/1269: 52.9 kW (71 hp). SAE J1349: 52.2 kW (70 hp). DIN 70020: 54.4 kW (73 hp / 74 PS). The commonly quoted 70 hp flywheel figure is the SAE J1349 net rating. |
| Torque rise | 25 percent at 1400 rpm |
| Altitude derating | No derating required up to 2300 m (7500 ft) altitude |
| Emissions certification | Not published in factory literature reviewed for this generation (circa-2000, predates formal Tier emissions labeling for this power class). Verify current emissions status with a dealer if needed for compliance purposes. |
| Electrical system | 12-volt direct-electric gear-reduction starter; 55-amp alternator standard with ROPS canopy, 90-amp alternator standard with optional cab; 12-volt, 900 CCA, group 31 maintenance-free battery with disconnect switch; in-cylinder glow plugs with built-in temperature switch |
| Cooling/air system | Conventional core radiator with 533 mm (21 in) fan; dry-type air cleaner with primary/secondary elements and restriction indicator; multi-plate water-cooled oil cooler |
Transmission / Drivetrain
| Type | Torque-converter powershift. Single-stage torque converter bolted directly to the engine flywheel housing (no separate driveshaft), feeding a powershift planetary transmission. A reported 3 speeds forward / 3 reverse is cited for this exact serial-prefix machine, but that speed count is only lightly corroborated — confirm exact gear count with a dealer or the model-specific OMM. |
| Steering | Multiple-disc steering clutches, one per side, spring-engaged and hydraulically released; oil pressure acting on a piston disengages drive to that track. Each clutch pairs with an external contracting brake band around the same drum to hold or pivot-turn that side. Actuated by clutch/brake pedals, not a single-joystick hydrostatic control — the core mechanical difference from the related 933C Hystat. |
| Service brakes | Externally contracting brake bands integral to the steering clutch packs, pedal-actuated. |
| Parking brake | Not separately documented for this torque-converter driveline in available sources (the wet multi-disc automatic parking brake spec published in 933C Hystat literature is specific to that hydrostatic drive and is not carried over here) — verify with a dealer. |
| Final drives | Outboard planetary reduction at each track sprocket, downstream of that side's steering clutch/brake pack, mounted independently of the track frames to isolate them from ground-induced shock loads. Standard and LGP undercarriages use different final drive housings. |
Weights
| Standard arrangement, GP bucket | 8,485 kg (18,690 lb) — approximate, includes coolant/lubricants, full fuel tank, ROPS canopy, bucket, 75 kg (165 lb) operator and recommended counterweight, no teeth/segments |
| Standard arrangement, MP bucket | 9,010 kg (19,845 lb), same basis as above |
| LGP arrangement | 8,744 kg (19,260 lb), same basis as above |
| Cross-source note | Some spec aggregators list the standard/GP configuration at roughly 18,706 lb rather than 18,690 lb — a small rounding/configuration variance (likely counterweight or teeth option), not a contradiction. Treat operating weight as 18,690-18,850 lb (approx 8,480-8,550 kg) for the standard GP configuration depending on exact options. |
| Weight change - ROPS cab (vs canopy) | +204 kg (+450 lb) |
| Weight change - Air conditioning | +66 to +88 kg (+146 to +194 lb) depending on configuration |
| Weight change - 3-tooth ripper | +17 to +249 kg (+37 to +549 lb) depending on whether rear counterweight is removed to compensate |
| Rear counterweight options | Six counterweight options offered, from about 99 kg (217 lb) up to 621 kg (1,370 lb) per plate, to balance different front-end configurations |

| Track rollers / shoes per side | 6 rollers per side and 39 track shoes per side, same for Standard and LGP undercarriages |
Performance
| Travel speed | Not published as a fixed forward/reverse speed table for this torque-converter powershift version in available sources. Hystat-equipped 933C/933C Hystat literature publishes a stepless 0 to 9.0 km/h (5.6 mph) hydrostatic range, which does not carry over to this powershift machine's fixed-gear speeds. Confirm exact gear speeds with a dealer or the model-specific OMM. |
| Drawbar pull | Published as a drawbar pull-versus-speed curve in 933C Hystat factory literature only (approximately 90 kN / 20,000 lbf at low range near 1 km/h, tapering to roughly 10 kN / 2,300 lbf at 9 km/h top speed) — a hydrostatic-drive curve that does not directly apply to this torque-converter powershift version's fixed-gear pull figures, which were not found published separately. Treat as a directional reference only; confirm exact figures with a dealer. |
| Ground pressure - Standard undercarriage | 54 kPa (7.82 psi), ground contact area 15,420 sq cm (2,390 sq in) |
| Ground pressure - LGP undercarriage | 32.8 kPa (4.76 psi), ground contact area 26,100 sq cm (4,045 sq in) |
| Gradeability | Not published in the factory literature reviewed for this model — request from a dealer if needed |
| Breakout force | GP bucket: 77.4 kN (17,390 lb). MP bucket: 71.3 kN (16,016 lb). LGP bucket: 83.6 kN (18,792 lb) |
| Static tipping load | GP bucket: 5,827 kg (12,834 lb). MP bucket: 5,626 kg (12,392 lb). LGP bucket: 5,630 kg (12,400 lb) — measured at operating weight with ROPS canopy |
| Hydraulic cycle times | Raise 5.8 sec; dump 1.7 sec; lower (empty, float down) 2.0 sec; total cycle 9.5 sec |
Buckets (loader buckets - this is a track-type loader, not a dozer, so no blade line is published)
| General Purpose (GP) bucket | Rated/nominal heaped capacity 1.00 cu m (1.3 cu yd); struck capacity 0.84 cu m (1.1 cu yd); width 1,969 mm (77 in) |
| Multi-Purpose (MP) bucket | Rated/nominal heaped capacity 0.96 cu m (1.25 cu yd); struck capacity 0.79 cu m (1.03 cu yd); width 1,969 mm (77 in). Designed for excavating, loading, stripping, dozing and cleanup work |
| LGP bucket | Rated/nominal heaped and struck capacity both 0.96 cu m (1.25 cu yd); width 2,330 mm (92 in) |
| Bucket features | Reversible bolt-on cutting edge segments, bolt-on corner guard system, optional backdrag edge for grading, solid-plate lift arms with crossmember reinforcement, replaceable bottom plates, sealed loader linkage rated to 50 service meter hours between greasing |
| Optional ripper | Rear-mounted ripper with 3 teeth and its own hydraulic cylinder is offered as an attachment; additional ripper teeth available separately. Not a dozer-style blade — this loader's product line does not publish S/SU/A/VPAT blade capacities |

933 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase w/ filter (Cat 3046, 5.0L 6-cyl diesel) | 13.25 L (3.5 US gal) | Cat DEO (Diesel Engine Oil), API CH-4/CI-4 or Cat ECF-2 spec, SAE 15W-40 general use. Select grade by ambient temperature per Cat's engine oil viscosity chart: lighter grades (SAE 0W-20/0W-30/5W-30) in cold climates, heavier (SAE 40/50) in sustained heat. |
| Cooling system | 21.2 L (5.6 US gal) | Cat ELC (Extended Life Coolant) or Cat DEAC, mixed 50/50 with water. Do not mix ELC with conventional coolant; top off with the same type already in the system. |
| Fuel tank | 157.08 L (41.5 US gal) | No. 2-D diesel fuel meeting Cat's fuel spec, minimum cetane 40. Switch to No. 1-D or a winterized blend below about -7 deg C (20 deg F). |
| Transmission / torque converter oil | n/a (see recommended) - refill volume not documented in any source accessible for this research | Cat TDTO (Transmission/Drive Train Oil), TO-4 spec. SAE 30 grade for temperate service; Cat TDTO-TMS (multi-season, covers SAE 0W-20/0W-30/5W-30) for cold-climate work. Service notes for this exact machine describe the transmission case filled through two plugs at the top of the housing, but no liter figure for this fill was found. |
| Steering clutch compartment oil | n/a (see recommended) - separate small-volume compartment per side, no liter figure documented | Same Cat TDTO / TO-4 fluid as the transmission. On this machine the steering clutch compartment on each side is independent of the main transmission sump - filled through a plug at the top of the final drive housing and checked with a small Allen-head level plug above the final drive on each side. |
| Final drives (each side) | Reported as approx. 14 L (3.7 US gal) on standard undercarriage vs approx. 20.82 L (5.5 US gal) on LGP undercarriage - figure appears in only one aggregator source, treat as approximate and unconfirmed | Cat TDTO, TO-4 spec, same fluid family as transmission and steering clutch oil. |
| Hydraulic system / tank | 57.15 L (15.1 US gal), full implement hydraulic system including tank | Cat TDTO or Cat HYDO Advanced 10, depending on arrangement. Small Cat track-type loaders of this era vary on whether the implement hydraulic circuit shares transmission oil or runs a dedicated HYDO fill - check the machine's own fluid data plate before servicing. |
| Grease (chassis, pins, bushings, idlers, rollers) | n/a (see recommended) | Cat Multipurpose Grease, NLGI 2, moly-fortified (approx. 3% moly). Standard Cat construction-equipment chassis grease spec for this class of machine. |
| Transmission type | n/a (see recommended) | Single-stage torque converter bolted directly to the engine flywheel housing, no separate driveshaft between converter and transmission, feeding a powershift planetary transmission. Independent sourcing on this exact serial-prefix machine describes 3 forward / 3 reverse speeds; treat the speed count as reported but only lightly corroborated. |
| Steering system | n/a (see recommended) | Multiple-disc steering clutches, one per side, spring-engaged and hydraulically released - oil pressure acts on a piston that moves the clutch yoke to disengage drive to that track. Each clutch pairs with an external contracting brake band around the same yoke/drum to hold or pivot-turn that side. Actuated by clutch/brake pedals, not a single hydrostatic joystick - the core mechanical difference from the 933C Hystat. |
| Final drive type | n/a (see recommended) | Outboard planetary reduction final drive at each track sprocket, downstream of that side's steering clutch/brake pack. Standard and LGP (wide-track) undercarriages use different final drive housings, with LGP taking noticeably more oil per the one source found for that figure. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 933 beyond the schedule
Predictive Maintenance & Fluid Analysis
Run fluid sampling on engine oil, torque converter and powershift oil, and planetary final drive oil at 250- and 500-hour draws to catch steering clutch or gear wear before it reaches the discs or planetaries. Track torque converter oil temperature and stall speed trends; rising temperature under load often signals a restricted oil cooler before outright failure. Coolant analysis flags corrosion in the 3046 diesel's cast passages early. Measure undercarriage pitch elongation regularly to schedule chain, roller, and sprocket replacement before it accelerates.
Corrective & Common Repairs
Steering clutch drag or slippage and worn brake bands are the most common driveline complaints on this powershift 933; both trace to disc wear inside the steering clutch case and respond to adjustment before full disc replacement is needed. Torque converter oil cooler restriction, often from packed demolition debris, causes converter overheating and power loss. Final drive seal leaks show up as oil on the inner rim near the sprocket. Track idler recoil springs and track adjusters wear from constant tension cycling and are frequent field repairs.
Overhaul & Rebuild Points
Steering clutch and brake disc packs reach a wear limit that calls for full pack replacement rather than further adjustment. Planetary final drive bearings, seals, and gear sets are rebuilt as a set once case-drain sampling shows metal. The torque converter's impeller, turbine, and stator warrant inspection once stall speed drifts from spec. Undercarriage rebuilds - chains, rollers, idlers, and sprockets - come due together once pitch wear passes tolerance. The 3046 diesel's inframe overhaul point follows standard compression and blow-by checks at top engine hours.
Seasonal & Environment Servicing
Cold starts on the 3046 diesel benefit from checking starting-aid function and coolant concentration before winter; block heater use protects torque converter oil from cold-start lag. Hot, dusty demolition or landfill sites shorten air filter and radiator-core cleaning intervals well below the standard 250- or 500-hour points. Wet or muddy ground calls for closer track sag checks, since standard tension settings pack with mud and overload the steering clutch and final drive seals. Adjust battery and electrical checks for temperature extremes.

933 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 100-01 | Engine oil pressure low | Low oil level, worn oil pump, plugged oil filter, or a faulty oil pressure sensor/wiring | Stop engine, check oil level and filter condition, then check sensor wiring before restarting |
| 110-00 | Engine coolant temperature high | Low coolant, plugged radiator core, slipping or broken fan belt, or faulty water temperature sensor | Idle engine to cool, check coolant level and radiator/fan for debris, verify sensor reading against a known-good gauge |
| 111-01 | Engine coolant level low | Coolant leak in radiator, hoses, or head gasket, or a faulty coolant level probe in the header tank | Check for visible leaks, top off coolant to specification, retest probe circuit if level is confirmed full |
| 168-04 | System/battery voltage below normal | Weak or failing alternator, loose or corroded battery cables, or a bad ground connection | Test charging output at the battery with engine running, clean and tighten all battery and ground connections |
| 168-03 | System/battery voltage above normal | Faulty voltage regulator inside the alternator causing overcharging | Load-test the charging system and replace the alternator or regulator if output exceeds specification |
| 177-00 | Powershift transmission oil temperature high | Low transmission fluid, plugged transmission oil cooler, or clutch pack dragging from excessive load | Reduce load and idle to cool, check fluid level and cooler for restriction, inspect for slipping clutches if temperature stays high at normal load |
| Hydraulic filter bypass lamp | Hydraulic system return filter is restricted and oil is bypassing the element unfiltered | Filter element loaded with debris or contamination, or oil too cold/viscous on startup | Let hydraulic oil warm up before heavy work; if lamp stays on at operating temperature, replace the hydraulic filter element |
| 2-digit action lamp flash sequence | General-purpose flash-code protocol used by the machine's amber action/warning lamp to announce any monitored fault | Any sensor or circuit condition tracked by the machine's electronic monitoring system, identified by the specific CID it flashes | Count the flash groups to read the two-digit code, then cross-reference it against the machine's CID list or connect a Cat electronic service tool for the full CID-FMI detail |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
933 attachments & work tools
Blades
The 933 line (933F, 933G, 933C) is sold as an integral-bucket crawler loader on a D4-size undercarriage, not as a blade-equipped dozer, so no factory S/SU/U/VPAT blade option is catalogued against the loader itself. Field and vintage listings show 933F/G units fitted with straight dozer blades on the same D4/D5-class frame, but this reads as a site conversion rather than a cataloged Cat option. If a blade is needed on this frame size, cross-reference the D3-D7 class SU blade (roughly 2.4-3.0 m / 8-10 ft wide depending on S vs SU vs U profile) and confirm mount compatibility with your dealer before ordering.
Rippers
Multi-shank hinge-type rippers (five-shank parallelogram frame, single cylinder) are catalogued for the D3B/C, D4B/C and D5C dozers and for the sibling 931B/C, 935B/C and 939/939C crawler loaders that share the same D4/D5-size undercarriage as the 933. The 933 itself is not named directly on most of these compatibility lists; given the shared chassis size class, cross-application is plausible but shank-mount profile should be verified with the dealer before fitting. Single-shank versions of the same frame are the lighter-duty alternative where full multi-shank pull isn't needed.
Winches
No Cat-documented winch option was found for the 933/933C loader family. Factory-style hydrostatic and PCU-pattern towing winches on this size of undercarriage are catalogued against the D4 and D5 straight track-type tractor line, not against the integral-loader 933/935/939 family, so a winch is not a stock attachment path for this machine — treat any winch fitment as a non-standard conversion.
Drawbars/counterweights
The LGP undercarriage variant (933 and 933C alike) carries counterweighted idlers as part of its wider low-ground-pressure track roller frame, which is the main counterweight-style feature documented for this family; standard and LGP roller frames are the two chassis configurations Cat offered. A rear drawbar/pull hook is consistent with this loader/dozer-derived chassis for towing or rear-tool mounting, but detailed drawbar capacity figures were not found in available literature — confirm rating with the dealer for towing or rear-attachment work.
Cab/ROPS guarding
933-era machines (933F/G/C) predate Cat's current pressurized, sound-suppressed ROPS/FOPS cab standard used on the modern 953/963 track loaders. Open ROPS canopy is standard on the 933 family with an enclosed cab as an option; there's no factory forestry/waste guarding package documented for this generation. For timber or waste-handling duty, aftermarket rear-end guarding and screened window protection over the ROPS/cab structure is the practical route, not a Cat-catalogued forestry kit.
Hydraulic arrangement
On this torque-converter powershift 933, loader bucket lift and tilt run off an implement hydraulic circuit fed by an engine-driven pump into a shared reservoir (roughly 57 L / 15 US gal), filtered through spin-on filters at the rear access door; control is via lever(s) or a pilot-operated valve bank acting on the lift/tilt cylinders. Drive power on this machine is entirely mechanical through the torque converter and steering clutches, not hydrostatic, so there is no drive-pump/motor circuit to service on the implement side — that hydrostatic drive circuitry belongs only to the separate 933C Hystat. No standard rear third-function or auxiliary valve is documented, so a rear-mounted ripper or other rear tool needs an add-on auxiliary valve rather than a stock circuit.

933 serial number reference
The PIN/serial plate on vintage 933/933F/933G units is stamped on the main frame, typically near the operator's platform or front support; on the modern reissue (933, 933C, 933C LGP Hystat) it is on the left side of the machine on the support arm in front of the cab. Pre-2002 serials read as an 8-character code - a 3-character prefix (letters plus one digit, e.g. 4MS) followed by a sequential unit number (e.g. 4MS12345). 2002-and-newer machines carry a full 17-character PIN (e.g. CAT0973CD4MS12345) with that same 3-character prefix embedded mid-string; match the prefix, not the trailing sequence number, to identify the specific production run.
| Prefix | Identifies | Notes |
|---|---|---|
| 11A | Original 933 track-type loader, early production | Introduced November 1954, USA-built. One-cubic-yard bucket with loader frame built into the chassis. Cat D311 4-cylinder naturally aspirated diesel, roughly 50 flywheel hp, 4-speed manual transmission via oil clutch. Started on D2-sized undercarriage, which proved undersized in service; components were upsized to D4-scale parts around serial 11A2956-up (this upsized version was produced internally as the 933 series E through 1958). Runs into the 42A-prefix 933F that followed in 1958. |
| 42A | 933F / 933G track-type loader, USA-built | USA production run covering both the 933F (from 1958) and its 933G update. 933F carries the D311 naturally aspirated 4-cylinder diesel and manual transmission; a forward/reverse lever was added starting at 42A02106 (1961), alongside a larger 1.12 cubic yard bucket. The 933G update (introduced 1965, sources also give 1968 for run's end) switched to the D320 turbocharged 4-cylinder diesel (about 60 flywheel hp, up from 50); G-series start point is given as either 42A06164 or 42A05918 depending on source - treat as a range, confirm exact break with dealer. Series discontinued 1968; total 933F/933G production across USA and Australian plants is estimated at roughly 6,900 units by some sources, though other sources put it over 9,000 - treat as approximate, not a confirmed figure. |
| 25A | 933F / 933G track-type loader, Australia-built | Australian-built counterpart to the 42A run, same 933F-to-933G generation split and engine change (D311 NA to D320 turbo). Production began in 1959, a year after the USA line started. Forward/reverse lever added starting at 25A00201 (1961). 933G update begins at 25A00558 (source-given date 1965, also seen as 1968). Discontinued 1968 alongside the USA line. |
| 8FL | 933 track-type loader, modern reissue | Later, unrelated-lineage reissue of the 933 name, produced roughly 1994-2003, distinct chassis from the vintage 11A/42A/25A machines. Non-Hystat variant: Cat 3046 6-cylinder diesel engine (5.0L, factory-shared design with the Mitsubishi S6S), powershift transmission. Part of the same small-track-loader family line that also included the Hystat-drive 933C and 939C models. Pre-2002 units use 8-character serials in this prefix format; 2002-and-newer units carry a 17-character PIN with the prefix embedded mid-string. |
| 4MS | 933C / 933C LGP Hystat track-type loader | Covers both the standard 933C and 933C LGP Hystat configuration - service literature for each cites the same 4MS prefix. Hystat (hydrostatic) drive and steering. Cat 3046 6-cylinder diesel engine (5.0L, same basic engine family as the Mitsubishi S6S). Shares its running gear and engine family with the D3C/D4C/D5C-III dozer line and the 939C Hystat loader, but 4MS itself is the 933C-specific prefix. |
| 5JS | 933C Hystat track-type loader, later serial range | Appears alongside 4MS in 933C Hystat/939C Hystat combined operator documentation as a later production-range prefix; parts-catalog cross-reference ties 5JS specifically to the 933C. Because the same combined manual also bundles 6DS in with it, confirm the exact 933C-vs-939C boundary for this prefix with a dealer before relying on it for parts lookup. Do not confuse with 6DS, which sourced evidence ties specifically to the 939C, not the 933C. |
Frequently asked questions
What engine powers the Cat 933 track-type loader?
This generation of the 933 (1994-2003, 8FL serial prefix) uses the Cat 3046 six-cylinder diesel, rated around 70 hp (52 kW) SAE net, paired with a torque-converter powershift transmission rather than a hydrostatic drive.
What is the operating weight of the Cat 933?
Operating weight runs roughly 8.5 to 8.7 tonnes (about 18,700 to 19,200 lb), varying with bucket type (general-purpose vs multi-purpose) and undercarriage width (standard vs LGP).
What replaced the Cat 933 track-type loader?
This torque-converter powershift 933 was followed by the 933C and 933C Hystat, which switched to a single-joystick hydrostatic drive. Caterpillar had separately used the 933 name decades earlier, 1954-1968, on an unrelated mechanical-engine Traxcavator that was succeeded by the 931 in 1972.
What 933 owners discuss
On the vintage 933/933F/933G (D311/D320 mechanical diesel), what cooling-system quirk do owners keep running into?
Running these engines with the thermostat removed is a guaranteed overheat, not a maybe. The thermostat opens the top radiator hose and closes the internal bypass at the same time; pull it and most of the coolant just bypasses the radiator core entirely. Scale and rust plugging the radiator core is the other repeat complaint, usually cleared with an acid flush and rodding the tubes. Owners agree the first parts to fail once the engine does overheat are the O-ring seals on the No. 2 and No. 3 pre-combustion chambers, showing up as coolant level creeping down and coolant migrating into the head/rocker area. Keep the thermostat in, keep the core clean, and treat any repeat coolant loss as a pre-combustion-chamber seal check first.
What undercarriage wear pattern is typical across the vintage 933 family, and does it differ by series?
Wear pattern reading is consistent: idlers riding well back from the front of the frame (rather than pushed forward against the stops) is read as a sign of a tighter, less-worn chain, and sprockets are generally expected to show roughly half their new-part profile before a rebuild becomes worthwhile. There is a real component-size split across the lineage: the early 11A-prefix machines carry D2-size chains and rollers, while the later 42A-prefix 933F/933G run D4-size chain, rollers, and sprocket rims (though the sprocket hub itself stays D2-style on some of these). Cracked or broken track-tensioner springs come up repeatedly as a check-it-every-time item, since it's a common failure point independent of overall track wear.
Why do vintage 933G units get reported as popping out of reverse under load, and is it safe to keep operating one that does?
The most frequently cited cause in owner discussions is the forward/reverse idler gear wearing the corners off its teeth, which lets the gear ride out of mesh under load. Twisted or worn splines on the related shaft are named as a secondary cause. The repair is described consistently as one of the tougher transmission jobs on these machines: pulling the layshaft, and sometimes heat-straightening a twisted shaft, with parts sourced either through Caterpillar's legacy parts system or salvage. Because a machine that jumps out of gear under load can move or roll unexpectedly, treat this as a stop-and-fix item and have your dealer or a qualified transmission shop verify the repair before returning it to work.
How does the modern powershift 933 (3046 engine, 1990s-2000s, not the 933C Hystat) hold up according to owners, especially the transmission?
General sentiment on Cat's small track-loader powershift transmissions as a family (931/933/935) is that they're generally reliable. Where a plain powershift 933 has been reported sticking in a single gear, the checks owners point to are interlock/shift solenoid function and transmission charge pressure before assuming internal clutch-pack damage. Using anything other than a TO-4-spec transmission fluid is called out repeatedly as a failure cause across this Powershift family, so a fluid-type check belongs early in any shifting complaint. This is a separate drivetrain from the hydrostatic-drive 933C; don't carry hystat symptoms or fixes over to this powershift machine.
What electrical quirks come up on the vintage 933 series?
The recurring theme isn't a design flaw so much as sourcing difficulty: with the machine's serial plate often worn or illegible, owners struggle to pin down which era-specific starter and 24V generator/charging components apply. Once the correct-generation Delco-sourced starter and charging components are fitted, owners consistently report the machine starting instantly and holding a charge normally. If your data plate is unreadable, get the full serial confirmed before ordering electrical parts rather than guessing from a partial number.
What should someone check before buying a used 933, across any generation?
Nail down the full serial number and generation first: early 11A vintage, later 42A vintage (933F naturally aspirated vs 933G turbocharged), modern 8FL-prefix powershift, and the separate 933C Hystat all need different service data and parts, and mixing them up leads to ordering the wrong components. On the machine itself: confirm the engine starts and runs clean with no blow-by or unusual smoke; inspect the loader frame carefully right where the tilt and curl arms pin into the frame, a known stress-crack area; check track-tensioner springs for cracks; and estimate remaining undercarriage life, since a full undercarriage replacement can approach the cost of the machine itself on a small loader. Separately, if lift or tilt arms settle down on their own, owners note it's almost always worn internal cylinder seals rather than the ram or rod itself. Factor trucking into the deal too; a 933F-class machine runs close to 7,900 kg (about 17,500 lb).
What do real operators say about the 933's actual working capability?
Consensus is that it's a well-balanced, strong-for-its-size machine, good for clearing smaller overgrown brush and saplings in right-of-way type work, but not a machine for taking down large mature trees. A Cat track-loader bucket is described as noticeably stouter than a comparable skid-steer bucket, with a similar-class bucket able to lift on the order of 1,600 to 1,800 kg (3,500 to 4,000 lb). Owners comparing it to its bigger siblings (951, 955) note the 933 is fine for light, periodic work but that undercarriage rehab should be budgeted as a near-certain up-front cost on a used unit, and that a larger model may suit steady daily use better.
