Caterpillar 973

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 973 is a track-type loader built from 1987 to 2000, the original machine in Caterpillar's numbered 973 loader line. It runs a Cat 3306 DIT turbocharged diesel, a 10.5-liter inline-six rated at 210 hp (156.6 kW) net, paired with a hydrostatic transmission that drives each track through its own motor instead of a mechanical torque converter. Operating weight runs around 24,900 kg (54,900 lb) in standard configuration, with bucket capacity around 2.45 m³ struck / 2.83 m³ heaped depending on the bucket fitted. Cat offered the 973 in standard and low ground pressure (LGP) undercarriage configurations, with general-purpose, multi-purpose, and waste-handling bucket options for site work, quarry, and demolition duty. No earlier 973-series machine preceded it; the 973C picked up the line in 1999.

Caterpillar replaced the original 973 with the 973C in 1999, raising power and revising the hydrostatic controls. The 973D followed with further electronic refinement, and the line continued through the 973K before Cat reintroduced a new, much larger 973 nameplate on a different chassis running a Cat C9.3B engine. That later machine is unrelated in design; it just reuses the model number. In the used and parts market, the original 973 holds value for its mechanically straightforward 3306 engine and proven Hystat hydrostatic drive, both well within reach of independent shops. Buyers weigh undercarriage condition, Z-bar linkage pin and bushing wear, and hydrostatic pump/motor health closely, since those define how much service life a used unit has left. Parts support today runs mostly through aftermarket and rebuilt-component channels rather than new-OEM stock.

973 fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter)Not published in accessible spec sources for this machine — capacity for the installed 3306 DIT diesel varies by oil pan/filter configuration. Verify against the serial-specific OMM lubrication chart or a Cat dealer.Cat diesel engine oil (Cat DEO), viscosity grade selected by ambient temperature per Cat's standard SAE chart (typically SAE 10W-30 in the -18 to 40 C / 0 to 104 F band, heavier single or multi-grade for hotter climates, lighter for cold-start regions).
Cooling systemNot published in accessible spec sources for this machine. Verify against the serial-specific OMM.Cat heavy-duty diesel engine coolant/antifreeze (era-appropriate Cat DEAC-type or later Cat ELC extended-life coolant), mixed per Cat's specified concentration for the climate.
Fuel tank356 L (94.1 US gal), same figure for both Standard and LGP configurations.No. 2-D diesel fuel (or Cat-approved equivalent distillate diesel) meeting the machine's fuel specification.
Transmission/powertrainNot published in accessible spec sources for this machine. Note: the base 973 (and its 953/963 platform-mates) drives on a hydrostatic transmission — twin hydrostatic pumps/motors off the engine — not a torque-converter powershift with a separate bevel-gear-and-steering-clutch case like the mechanically-steered Cat track-type tractors/older loaders. There is no bevel gear/steering clutch compartment on this driveline; the hydrostatic drive case is the transmission compartment. Verify exact fill volume against the serial-specific OMM.Cat Transmission/Drive Train Oil (TDTO), viscosity grade (SAE 10W/30/50) selected by ambient temperature per the OMM chart.
Final drives (each)Not published in accessible spec sources for this machine; each side is filled/checked separately. Verify against the serial-specific OMM.Cat TDTO, same fluid family and climate-based viscosity grade as the drivetrain/transmission.
Hydraulic system/tank60 L (15.9 US gal).Cat TDTO (many Cat track-type loaders of this era run a shared drivetrain/hydraulic fluid) or Cat hydraulic oil (HYDO) per the OMM — confirm the exact designation against the serial-specific OMM, as this was not independently confirmed for this exact model.
Pivot shaftNo oil-fill capacity — this is the equalizer-bar pivot connecting the track roller frames to the main frame, serviced by grease fitting on the scheduled lubrication interval, not a refill volume.Cat Multipurpose Grease (NLGI 2).
Grease specs (general)N/A — applied per lubrication-chart interval at grease fittings, not a refill capacity.Cat Multipurpose Grease (MPGM, NLGI 2 lithium-complex) for general chassis and pin points; Cat Prime Application Grease (moly-fortified, NLGI 2) for heavy-load, high-pressure pivot points such as loader linkage and bucket pins, per Cat's standard lubrication-chart approach for this class of machine.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Caterpillar 973 maintenance schedule

Service intervalTasks
Every 50 h
  • Walk around and check track tension, shoe plates, and idler/roller seals for oil weep before starting.
  • Check engine crankcase oil and coolant level on the 3306 DIT with the machine on level ground.

  • Overhaul or exchange hydrostatic drive motors if performance or S·O·S trends have degraded.
  • Rebuild the Z-bar loader linkage pins, bushings, and tilt cylinder pivots as a set.
  • Evaluate undercarriage wear against OEM limits and budget for track chain, roller, and sprocket replacement.
Every 6,000 h
  • Plan a top-end or full overhaul of the 3306 DIT based on oil analysis and compression trends.
  • Rebuild or replace the hydrostatic pump and motors as a matched set.
  • Replace the undercarriage (track chain, rollers, idlers, sprockets) once wear passes service limits.
  • Rebuild the final drive planetaries and reseal the housings.

Servicing the 973 beyond the schedule

Predictive Maintenance & Fluid Analysis

Run S·O·S oil sampling on the 3306 DIT crankcase at every 250-hour oil change, and pull separate samples from the hydrostatic drive case and both final drive housings at 500-hour intervals. Rising iron or copper in a hydrostatic sample usually flags pump or motor wear well before a leak or noise shows up. Track coolant condition too. The 3306's wet-sleeve cylinder liners are prone to cavitation erosion if coolant additive falls off spec between changes.

Corrective & Common Repairs

Most corrective work on a 973 centers on the Z-bar loader linkage and hydrostatic drive. Expect to replace bucket and bell-crank pins and bushings as they wear loose, since the Z-bar geometry that gives this loader its breakout force also concentrates load on a few large pivot points. Hydrostatic drive motors and the variable-displacement pump are rebuildable rather than throwaway. Leaks at case seals and shaft seals are the common failure point, not the pump internals. Track adjuster grease-seal leaks are a frequent complaint on high-hour machines.

Overhaul & Rebuild Points

Plan an undercarriage rebuild or full track, roller, idler, and sprocket replacement once wear passes OEM limits. This is the single biggest rebuild cost on a used 973 and the first thing to inspect before buying one. Final drive planetaries typically go a full service life between rebuilds if gear oil is sampled and changed on schedule. On the engine side, budget a top-end or full overhaul of the 3306 DIT once oil analysis or a compression check shows the turbocharger, liners, or injectors trending out of spec.

Seasonal & Environment Servicing

Cold-climate 973s need a block heater and ether start aid to bring the 3306 DIT up to temperature before hydrostatic charge pressure builds properly; running the hydro system cold accelerates pump and motor wear. Keep coolant at the correct extended-life concentration for the region's low temperature. In hot, dusty quarry or demolition environments, shorten air filter and radiator core cleaning intervals and check the oscillating undercarriage and track seals more often, since abrasive fines accelerate bushing and seal wear faster than hour-based schedules assume.

Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

973 attachments & work tools

Blades

The 973 track-type loader's own work-tool lineup is built around buckets and a rear ripper, not a dozer blade line; its parts book has no blade, angle, or pitch-blade circuit, only lift/tilt (and pitch, for 4-in-1 buckets) bucket cylinders. Cat's S/SU/A trim designations and VPAT (variable-pitch, angle, tilt) blades belong to the D-series track-type tractor lineup and are not catalogued for this loader chassis. Where a straight push or trim blade is fitted to this loader family for wall-sweeping or grading, it is a simple bolt-on tool, not a VPAT-series blade — width/capacity varies by dealer setup and is not standardized like the tractor blade line.

Rippers

Factory ripper option is a rear-mounted parallelogram unit; catalog data shows a multi-shank beam with three shank pockets alongside separate single-shank/heavy-duty ripper part groups, so both single- and multi-shank arrangements were offered across the production run. The multi-shank beam is meant for frozen ground, asphalt, and hard soil/rock ripping with replaceable shank tips; a single, longer shank gives deeper penetration for tougher digging. Exact ripper weight is not consistently documented — treat published figures as approximate and expect them to vary by shank count and tip style.

Winches

No winch group appears anywhere in this machine's factory parts breakdown, unlike the winch sections found on Cat's D-series dozers of the same era — a towing/logging winch is not a documented catalog option for this track-type loader platform. Any winch seen on a used 973 is most likely a dealer or aftermarket fitment rather than a factory work tool, and coverage of this varies by source; verify fitment case by case rather than assuming factory support.

Drawbars/counterweights

The chassis parts book lists several distinct hitch groups, confirming factory-fit drawbar/pintle hardware was offered in more than one arrangement for towing duty. No separate counterweight group is catalogued for this machine; its rear-engine layout is documented as giving natural ballast against a loaded bucket, which is why a bolt-on counterweight — standard on front-engine dozers — was not needed here.

Cab/ROPS guarding for forestry/waste

The parts catalog documents Open ROPS, Enclosed ROPS, and a distinct Demolition ROPS arrangement, plus separate vandalism/screen guard groups for both open and enclosed cabs, a sound-suppression group, and a Steel Mill arrangement. The factory Demolition package pairs a windshield screen and full guard set with the sound-suppressed cab; later Waste Handler and Waste Handler Extreme Service guarding (protected final-drive, pivot, and idler seals, plus shielded hydraulic lines) extend the same protective concept for landfill, transfer-station, and demolition work. This loader family is also marketed for forestry and utility duty, but no separately named forestry guard package is documented apart from the demolition/waste-handler guarding lines — expect the same screen/guard hardware to be specified for forestry use.

Hydraulic arrangement front/rear tools

The catalog offers multiple 3-valve hydraulic arrangements built as front-only, rear-only, or combined front-and-rear circuits, each available with single-lever or 2-lever control, plus a diverter valve group that routes pump flow between circuits. The front circuit runs the bucket (lift and tilt, with a separate pitch circuit on multi-purpose/4-in-1 buckets); the rear circuit carries its own dedicated ripper cylinder and ripper lines group. This lets a machine ordered without a ripper spec the front-only 3-valve setup, while a ripper-equipped machine adds the rear valve, lines, and cylinder package without touching the front bucket circuit.

973 serial number reference

The PIN/serial plate on a 973 track loader is riveted to the left side of the mainframe, on the support structure just ahead of the cab entry step, with the number often restamped nearby on the frame itself. Read the first three characters as the serial number prefix (identifies the specific production/parts-book series), and the digits that follow as the sequential unit number within that series — on pre-2000s machines this is typically shown as a short prefix plus up to a 5-digit sequence (e.g. 86G03344).

PrefixIdentifies
32Z973 (earliest production run)
86G973 (main production run, Std/LGP)
90L973 (limited parallel/export run) — confirm with dealer
91L973 LGP (limited parallel/export run) — confirm with dealer
MKL973K and current-generation 973 (2018-present reissue) — separate machine, not the classic 973 above

Frequently asked questions

What engine does the Caterpillar 973 track-type loader use?

The original Caterpillar 973 (1987-2000) runs a Cat 3306 DIT turbocharged diesel, a 10.5-liter inline-six rated at 210 hp (156.6 kW) net, paired with a hydrostatic transmission that drives each track independently. This differs from the later 973C and 973D, and from the 2023-2024 reintroduced 973, which uses a Cat C9.3B engine.

What is the operating weight of the Caterpillar 973 track-type loader?

Operating weight for the original 973 in standard configuration runs around 24,900 kg (54,900 lb). Low ground pressure (LGP) versions and different bucket or counterweight setups shift this figure somewhat, so check the machine's specific configuration against its plate.

What replaced the Caterpillar 973?

Caterpillar replaced the original 973 with the 973C in 1999, followed later by the 973D and eventually the 973K. Cat has since reintroduced a new, unrelated 973 nameplate on a larger, modern chassis with a Cat C9.3B engine; it is not a direct descendant of this original 973 generation.

What 973 owners discuss

What do owners and mechanics generally say about the 973 powertrain?
General consensus is that the 3306 DIT engine and per-track hydrostatic drive are solid, with no widespread inherent design fault. Problems that come up usually trace to deferred maintenance or poor repairs by a previous owner, not the design itself. A simple field check: if both tracks spin evenly, the machine tracks straight, and it turns cleanly in both directions, the powertrain is likely sound. High idle should settle around 2320 rpm (plus or minus 50), and rpm under full load should hold at roughly 1850 to 1950 rpm. A machine that bogs well below that range at full pump stroke points to a fuel system or turbocharger issue, not the hydrostat.
Why does a 973 lose drive or stop moving after it warms up?
The most commonly reported cause is charge pressure loss in the drive loop as the machine ages, sometimes traced to wear on the aluminum plate behind the control valve, sometimes to an external leak. Typical pattern: the loader drives fine cold, then goes weak or quits moving after 10 to 15 minutes once the roughly 70 L (about 18.5 gal) of hydrostat oil is fully hot and thinner. Proper diagnosis uses test gauges in the 41 to 55 bar (600 to 800 psi) range tapped into the HPCU test ports, plus a check of cooler return flow under load, which should stay above roughly 60 L/min (16 gpm) with oil around 79°C (175°F). If pressure and flow check out but the machine still won't move, the next suspects are the drive motors and the brake circuit, not the charge pump. Have a dealer or qualified tech verify brake circuit pressure before returning the machine to work, since a weak brake and a weak drive can look similar from the seat.
What undercarriage wear should owners watch for on a 973?
Wear pattern is typical of a heavy sealed-and-lubricated track machine: sprockets, rollers, idlers, and chain pitch elongation are the big wear items, and a full track group replacement is a major expense once it's due. The field check is visual: sprocket teeth should be blunt, not sharp or hooked, and the area where the chain rides on the sprocket should still be round rather than worn into an egg shape. Machines working in heavy impact conditions (rock, demolition) commonly get reinforced or outrigger-style track options fitted aftermarket to slow this wear compared to standard chain.
Are there known quirks with the 3306 DIT engine in this machine?
Some oil consumption is considered normal on a high-hour 3306 DIT. Owners describe usage approaching 3.8 L (about 1 gal) between changes on tired engines without it being a red flag by itself. White smoke on cold start, on deceleration, or when reapplying throttle after idling is described as typical turbo and aftercooler behavior rather than a fault. What is a genuine warning sign: smoke or oil coming from the air intake side rather than the exhaust, which points to a failing turbocharger shaft seal dumping oil into the intake tract and should be checked before it damages the turbo further. A cracked aftercooler core from age and corrosion is the other common failure; it shows up as steady coolant loss paired with heavier exhaust smoke.
What electrical or sensor issues come up on the 973?
This machine predates factory touchscreens and electronic engine controls, so the electrical system is simple compared to later Cat loaders. Reported nuisance faults are mostly mechanical-adjacent: pressure switches feeding gauges and warning lights drift or fail with age, and harness sections routed near the tracks or the hydrostat pump can chafe through at clamp or zip-tie points from vibration, causing intermittent shorts that look like a sensor fault. Before condemning a sensor when a gauge or warning light reads wrong, check harness routing and switch connections first. Have a dealer or qualified tech verify any suspected charging-system or safety-interlock wiring fault before putting the machine back in service.
Steering feels heavy or uneven. What's the common cause?
A leak in one of the servo lines under the top cover linkage is a commonly cited cause of sluggish or one-sided steering response, since it affects how cleanly the pump gets signaled to send flow to that side's drive circuit. Corroded or stiff steering pedal pivot bearings are also frequently mentioned; they restrict full pedal travel and can make the machine feel like it won't turn sharply even when the hydraulic side is fine. Check the simple mechanical pivot for binding before chasing the servo linkage. Have a dealer or qualified tech verify steering circuit pressures if the fix isn't obvious, since steering response is safety-critical on a machine this size.
What should a buyer check before purchasing a used 973?
Put most of the pre-purchase attention on the undercarriage and the hydrostatic drive, since those are the two most expensive systems to put right. On the tracks: sprocket teeth should be blunt rather than sharp or hooked, and the chain-to-sprocket contact area should still be round, not worn egg-shaped. On the hydrostat: run the machine until it's fully warmed up and confirm it still holds power and travel speed, not just at cold startup, since charge pressure and seal problems often only show up once the oil is hot. Dark, burnt-smelling hydrostat oil is treated as a warning sign of internal wear or an overheating history. If the seller allows it, pull fluid samples of engine oil, hydrostat oil, and coolant for lab analysis, since that can catch internal problems a walk-around inspection misses. Have a dealer or qualified tech pressure-test the hydrostat and brake circuits before final purchase, since those are the costliest and most safety-critical systems to get wrong.
