Caterpillar D6T

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar D6T is a mid-size track-type tractor (crawler dozer) in Cat's D6 class, positioned between the smaller D5 and larger D7/D8 dozers. Built from roughly the mid-2000s through 2019, it was powered across its run by the Cat C9 ACERT (Tier 3/Stage IIIA, early production) and later the re-rated Cat C9.3 ACERT (Tier 4 Interim/Stage IIIB, then Tier 4 Final/Stage IV with selective catalytic reduction), an inline six-cylinder diesel netting roughly 200-215 hp (149-160 kW) depending on emissions tier and series. Operating weight spans roughly 18 to 24.5 tonnes (about 40,000 to 54,000 lb) depending on configuration, from the standard XL undercarriage up through wide-track LGP and VPAT-blade variants. The D6T succeeded the D6R (built roughly 1996-2005) and was itself replaced starting in 2019 by Caterpillar's next-generation D6 and electric-drive D6 XE dozers. Cat offered the D6T in multiple factory configurations, including XL, LGP (low ground pressure), XW (extra-wide), and WH (waste handler) undercarriages, paired with straight, angle, semi-universal (SU), or variable-pitch angle-tilt (VPAT) blades, plus optional single- or multi-shank rippers.

Across its production run the D6T saw two major powertrain updates driven mainly by emissions regulation rather than a full model redesign: the original Tier 3/Stage IIIA C9 ACERT gave way to a Tier 4 Interim/Stage IIIB C9.3 ACERT around 2011-2012, then to a Tier 4 Final/Stage IV version using diesel exhaust fluid dosing by roughly 2014-2015. Partway through production Caterpillar also moved the standard transmission from a 3-speed to a fully automatic 4-speed powershift paired with electrohydraulic differential steering, improving fuel economy and control without changing the machine's basic footprint. Because the D6T was built in high volume for well over a decade and shares its C9/C9.3 ACERT engine family, differential-steering powertrain, and undercarriage architecture with siblings like the D6N and early D6, it remains one of the most common mid-size dozers in the used equipment market today, supporting strong parts interchange and sustained demand for engine, transmission, final drive, and undercarriage components well after factory production ended.

D6T fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter)24.6 L (6.5 US gal) - Cat C9.3 ACERT Tier 4 Final/Stage IV/Korea Tier 4 Final engine, D6T Build 19 (2016+). Figure agrees across two independent official Cat D6T spec sheets.Cat DEO-ULS (API CJ-4, meets Cat ECF-3/ACEA E9) is required for this Tier 4 Final aftertreatment-equipped engine; Cat DEO (API CI-4/CI-4 PLUS) acceptable on pre-Tier 4 engines only. Viscosity by ambient temperature per Cat OMM: SAE 10W-30 (-18 to 40°C/0 to 104°F), SAE 15W-40 (-10 to 50°C/14 to 122°F), Cat DEO-ULS SYN 5W-40 (-30 to 50°C/-22 to 122°F), Cat DEO Cold Weather 0W-40 (-40 to 40°C/-40 to 104°F) for cold-soaked starts. Commercial oils meeting Cat ECF-3 are second-choice.
Cooling system46 L (12.2 US gal), D6T Build 19 (confirmed in two independent 2016 Cat spec sheets). Note: the later, technically distinct next-generation D6/D6 XE model (different product line, C9.3B engine) lists 63 L for D6 and 77 L for D6 XE - do not confuse with D6T.Cat ELC (Extended Life Coolant) is factory-fill/preferred (up to 12,000 hr or 6-year service life, with one Cat ELC Extender addition at mid-life); Cat DEAC conventional heavy-duty antifreeze/coolant is an acceptable alternative requiring periodic SCA additions (3-6% concentration). Minimum 30% glycol is required (50% recommended) because the D6T engine uses air-to-air aftercooling (ATAAC) - water-alone or water/SCA-only coolant is NOT permitted in ATAAC-equipped engines. Factory coolant options rated to -37°C (-35°F) standard or -51°C (-60°F) arctic extended-life coolant.
Fuel tank368 L (97.2 US gal), D6T Build 19 (confirmed in two independent 2016 Cat spec sheets: AEHQ7974 and AEXQ1969).Ultra Low Sulfur Diesel (ULSD, ≤15 ppm/mg-kg sulfur) is required for this Tier 4 Final/Stage IV/Korea Tier 4 Final engine with exhaust aftertreatment. Biodiesel blends up to B20 are acceptable when blended with ULSD, meeting ASTM D7467 (blend stock meeting Cat biodiesel spec, ASTM D6751, or EN 14214).
DEF (Diesel Exhaust Fluid) tank17.1 L (4.5 US gal), D6T Build 19.Diesel Exhaust Fluid meeting ISO 22241 (approx. 32.5% urea solution) for the Cat SCR aftertreatment system; heated DEF tank/lines with electronic fill indicator are standard equipment.
Power train - powershift transmission and bevel gear/steering clutch compartment (combined system per Cat OMM)148 L (39.1 US gal) total - the D6T Operation & Maintenance Manual and parts documentation treat the powershift transmission and bevel gear/steering compartment as a single combined 'Power Train' refill system with a shared drain point, rather than listing separate transmission-only and bevel-gear-only capacities.Cat TDTO (Transmission/Drive Train Oil, meets Cat TO-4 spec) or Cat TDTO-TMS (meets TO-4M, multigrade) - this compartment contains friction material/clutches, so Cat FDAO or gear oil (Cat GO) must NOT be substituted. Viscosity by ambient temperature (Power Shift Transmission, normal duty, Track-Type Tractor category): Cat TDTO Cold Weather SAE 0W-20 (-40 to 10°C/-40 to 50°F), SAE 10W (-20 to 10°C/-4 to 50°F), SAE 30 - factory fill (0 to 35°C/32 to 95°F), SAE 50 (10 to 50°C/50 to 122°F), or Cat TDTO-TMS multigrade (-15 to 43°C/5 to 110°F).
Final drives (each side)13.5 L (3.6 US gal) per side, D6T Build 19 (cross-verified across two independent Cat spec sheets).Cat TDTO (meets Cat TO-4) - on the D6T, final drives fall under the same 'oval track-type tractor' differential gear box category shared with D5M/D5N/D6M/D6N (distinct from the D7E and larger elevated-final-drive tractors, which use Cat FDAO/FD-1 instead). Viscosity by ambient temperature: Cat TDTO Cold Weather SAE 0W-20 (-40 to 0°C/-40 to 32°F), SAE 10W (-30 to 0°C/-22 to 32°F), SAE 30 (-25 to 25°C/-13 to 77°F), SAE 50 - factory fill (-15 to 50°C/5 to 122°F).
Hydraulic system/tank62.5 L (16.5 US gal) hydraulic tank, D6T Build 19 (confirmed in two independent Cat spec sheets). Note: the later, technically distinct next-generation D6/D6 XE model separately lists a 60 L tank fill plus a 77 L total system capacity - do not confuse with the D6T's single 62.5 L tank figure.Cat HYDO Advanced is the preferred hydraulic oil, offering extended (up to 6,000 hr with S·O·S oil analysis) drain intervals versus second/third-choice oils; Cat Bio HYDO Advanced (ISO 46 biodegradable, factory option in EU rated to -37°C/-35°F) is available where environmental compliance is required. Viscosity by ambient temperature: Cat HYDO Advanced 10 / SAE 10W (-20 to 40°C/-4 to 104°F), Advanced 20 / SAE 20W (-5 to 45°C/23 to 113°F), Advanced 30 / SAE 30 (0 to 50°C/32 to 122°F).
Pivot shaft compartment (track roller frame recoil spring / pivot shaft bearings)5 L (1.3 US gal), D6T Build 19 (cross-verified across two independent Cat spec sheets).Cat TDTO (meets Cat TO-4), same oil family and viscosity grades as the power train and final drives: Cat TDTO Cold Weather SAE 0W-20 (-40 to 0°C/-40 to 32°F), SAE 10W (-30 to 0°C/-22 to 32°F), SAE 30 - factory fill (-20 to 25°C/-4 to 77°F), SAE 50 (0 to 50°C/32 to 122°F), or Cat TDTO-TMS multigrade (-25 to 25°C/-13 to 77°F).
Grease points (equalizer bar pins, angle/tilt blade brace, lift cylinder yoke bearing, fan drive belt tightener, winch drum bearing and fairlead rollers)Not a refill-capacity system - applied via grease gun at scheduled service intervals per fitting, not a sump volume.Grade/type depends on duty severity and ambient temperature per Cat's Track-Type Tractor grease-selection chart: high load (ditching, ripping, heavy maintenance, snow plowing) - Cat Extreme Application Grease NLGI 1 (-35 to 40°C/-31 to 104°F) or NLGI 2 (-30 to 50°C/-22 to 122°F); medium load (average road/maintenance work) - Cat Prime Application Grease NLGI 2 (-20 to 40°C/-4 to 104°F); low load (finish grading, light maintenance) - Cat Utility Grease NLGI 2 (-30 to 40°C/-22 to 104°F); fan drive bearings specifically use Cat Ball Bearing Grease NLGI 2 (-20 to 40°C/-4 to 104°F). For extreme climates, Cat Extreme Application Grease-Arctic NLGI 0.5 (down to -50°C/-58°F, semi-synthetic) or Grease-Desert NLGI 2 (moderate-to-hot conditions) are offered.

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

Servicing the D6T beyond the schedule

Predictive Maintenance & Fluid Analysis

Run S.O.S sampling on the D6T's C9/C9.3 ACERT engine oil, TDTO-filled powershift transmission and differential steering case, final drives, and HYDO hydraulic system at every scheduled change to catch bearing wear, coolant intrusion, or fuel dilution before a torque divider or final drive failure sidelines the machine. Because the transmission, differential steering, and bevel gear share oil galleries, a rising iron or copper trend in one TDTO sample often signals wear migrating through the whole powertrain, not just a routine filter change.

Corrective & Common Repairs

Common D6T corrective work centers on the differential-steering electrohydraulic controls, torque divider/lock-up clutch, and final drive face seals, which leak or lose modulation as hours climb, plus C9/C9.3 ACERT turbocharger and injector wear tied to duty cycle and fuel quality. On the undercarriage, expect sprocket segment, idler, and track link/bushing wear accelerated by ripping or high-impact dozing; sealed-and-lubricated SystemOne track groups cut bushing turn but still need regular tension and guiding-guard inspection.

Overhaul & Rebuild Points

Major D6T rebuild points fall around the powershift transmission and differential steering assembly, final drive planetaries, and the C9/C9.3 ACERT long block and turbocharger once S.O.S trending or valve-lash drift signals internal wear. Undercarriage overhaul, covering track chains, sprockets, idlers, and rollers, is typically the first big-ticket rebuild on high-hour machines, especially LGP and VPAT units run in abrasive or high-load conditions, and is best planned around wear-gauge readings rather than a fixed hour number.

Seasonal & Environment Servicing

In cold climates, protect the D6T's ELC coolant freeze point and confirm the correct DEO viscosity grade before cold starts, since the C9/C9.3 ACERT's emissions hardware on Tier 4 units is sensitive to prolonged idling and incomplete regeneration. In wet, muddy, or waste-handling environments, clear packed material from final drives and track frames often (WH-spec center-hole track shoes help on landfill units), and inspect radiator and hydraulic cooler fins regularly, since mud packing quickly reduces cooling capacity on this platform.

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

D6T attachments & work tools

Blades

The D6T offers Straight (S), Semi-U (SU), Angle (A) and VPAT (Variable Pitch Angle Tilt) blades. Typical capacities/widths: S blade ~3.79 m3 (4.96 yd3) at ~4,063 mm (13.3 ft); SU blade ~3.95 m3 (5.17 yd3) at ~3,261 mm (10.7 ft); A blade ~3.95 m3 (5.17 yd3) at ~4,160 mm (13.7 ft); VPAT ~4.64 m3 (6.07 yd3) at ~3,880 mm (12.7 ft). VPAT allows simultaneous hydraulic lift, angle and tilt plus manual pitch adjustment, useful for spreading, finish grading, side-casting, V-ditching and backfilling; exact blade width also varies with track gauge (XL, XW, LGP) and sub-variant (e.g. XL, XL Narrow, Landfill, XW).

Rippers

A single-shank parallelogram ripper (fixed or hydraulic parallelogram, 3 shank pockets, ~1,000 mm pocket spacing, shank section roughly 74 x 175 mm) is the base rear attachment, with reported weight (one shank fitted) of about 1,550-1,634 kg depending on source; each added shank is roughly 73-163 lb (33-74 kg) depending on measurement basis. Reported penetration force is about 65-69 kN and pryout force about 89-91 kN (~20,100 lbf), with max penetration near 450-460 mm (18 in). Multi-shank (up to three-shank) parallelogram rippers are also offered for this class, with total assembly weight ranging roughly 1.75-2.8 tonnes depending on the number of lift/tilt cylinders (1, 2 or 4) fitted; single-shank is favored for maximum penetration in hard/frozen ground while multi-shank suits shallower, higher-production loosening.

Winches

The D6T fits the Cat PA56 (and related PA55/PA56 slow-speed) power-shift, PTO-driven winch family used across this dozer weight class; it is electronically controlled, mounted at the rear in place of a ripper, and driven off the transmission/torque-converter PTO rather than hydraulically. Reported drum specs are about 254 mm (10 in) diameter x ~330 mm (13 in) width with bare-drum line pull cited between roughly 70,000 lb (rated) and up to ~89,800 lb (maximum) depending on source, and unit weight near 1,180 kg (2,600 lb); control is via a single lever for clutch/brake plus a separate freespool lever.

Drawbars/counterweights

In place of a ripper or winch, the D6T rear can be fitted with a drawbar for towing/recovery work or pulling towed implements (disks, compactors, chopper wheels, towed scrapers), with drawbar clevis height from the ground reported around 580 mm (23 in) on this class of machine. A rear counterweight option is also available to help balance the machine when running heavier front attachments (e.g., VPAT or straight blade) without a rear ripper or winch fitted; specific D6T counterweight/drawbar unit weights are not consistently published and should be confirmed against the current dealer configuration guide.

Cab/ROPS guarding

For forestry/land-clearing work, the D6T Forestry Arrangement adds optional sweeps protecting the cab roof and sides plus impact screens over the cab windows, with a Heavy-Duty/Forestry step-up adding impact-resistant polycarbonate doors and additional side/rear screens for debris protection. The related Waste Handler (WH) configuration instead emphasizes chassis-level guarding for landfill/waste duty: multi-layer labyrinth-style final drive guards, clamshell wire-wrap guards at final drives/idlers, pivot shaft seal guards, striker bars, extra seals limiting debris ingress to engine/transmission compartments, a heavy-duty hinged radiator guard with auto-reversing fan, and a hinged belly guard plus fuel tank/battery box and tilt-cylinder guarding; both arrangements use a ROPS/FOPS-rated, typically pressurized/sealed cab.

Hydraulic arrangement (front/rear tools)

The D6T uses a dual (twin) hydraulic pump arrangement with load-sensing implement hydraulics that dedicates flow separately to steering and to the blade/implement circuit, reported implement relief pressure in roughly the 21,500 kPa (~3,100-3,500 psi) range depending on blade type. The front blade circuit drives lift/angle/tilt (plus manual pitch on VPAT); the rear attachment point is hydraulically served by a dedicated ripper control valve/single lever for shank lift and tilt, while a rear winch, when fitted instead of the ripper, is mechanically PTO-driven off the powertrain rather than through the hydraulic implement circuit, making rear ripper and rear winch mutually exclusive attachment choices.

D6T serial number reference

The PIN/serial plate on a D6T is on the rear of the machine, high on the end of the left-hand frame rail, and can be hidden by ripper attachments. Caterpillar's post-2001 format is a 17-character PIN where the first 3 letters/digits are the model-and-build-series prefix (e.g., 2D2, KSB, SMC) followed by a sequential unit number (e.g., 2D200001-and-up). That 3-character prefix ties a given D6T to a specific configuration (XL/XW/LGP/VPAT, with or without Differential Steering or PAT/VPAT blade), engine generation (Cat C9 ACERT for Tier 3 and Tier 4 Interim builds, Cat C9.3 ACERT for Tier 4 Final/Stage IV builds), and assembly plant - so it should be looked up in Cat SIS or confirmed with a dealer rather than assumed from the model name alone. One verified edge case: the KJL prefix straddles two model lines - the tail end of D6R Series III production and the start of D6T production both used the KJL prefix, so a KJL serial must be checked against its numeric position (not just the letters) to confirm it is actually a D6T.

Frequently asked questions

What engine does the Caterpillar D6T use?

The D6T was built with the Cat C9 ACERT diesel (Tier 3/Stage IIIA, early production) and later the re-rated Cat C9.3 ACERT (Tier 4 Interim/Stage IIIB, then Tier 4 Final/Stage IV with selective catalytic reduction), an inline six-cylinder, 9.3-liter engine rated at roughly 200-215 hp (149-160 kW) net depending on series - check the emissions plate or serial number range to confirm the exact rating on a given unit.

What is the operating weight of a Caterpillar D6T?

Operating weight varies by configuration, from about 18.1 tonnes (40,014 lb) on lighter setups up to roughly 24.4 tonnes (53,829 lb) on wide-track LGP/VPAT configurations, with the common XL configuration running close to 21.7 tonnes (47,846 lb). Weight varies by blade, undercarriage, and counterweight configuration/series, so always check the specific machine spec.

What replaced the Caterpillar D6T?

Caterpillar discontinued the D6T around 2019 in favor of a next-generation D6 lineup: a conventional 4-speed powershift D6, and the D6 XE, Cat's first high-drive electric-drive dozer, which replaced the D6T's mechanical torque-divider driveline with an electric drive system while carrying forward a similar C9.3-based engine platform.

What D6T owners discuss

What do owners say about the D6T's transmission and torque divider, and what typically fails?
The D6T uses a fully automatic powershift transmission paired with a lock-up clutch torque divider — not a hydrostatic drive like the smaller electric-drive machines. The torque divider and steering-clutch housing share a common oil sump, so both compartments should be drained and serviced together rather than treated as separate systems. The most common failure story involves transmission oil and filters left unchanged for years: the filter ends up collapsed and packed with clutch material, pointing to a burned-out clutch pack from maintenance neglect rather than a design flaw. A 'won't move / stalls under load' symptom often traces to a sticking modulation valve that leaves multiple clutches engaged at once, making the transmission fight itself. Fluid and filter intervals are the single biggest lever an operator has over torque-divider longevity. Because a partial clutch-pack failure can also affect braking feel and directional response, have your dealer verify torque divider and steering-clutch health with a proper pressure/modulation check before returning the machine to normal duty.
Are there known engine quirks that differ by D6T model year?
Community sources are consistent that the D6T line spans at least two distinct engine families, and mixing them up causes confusion when sourcing information. Earlier D6T units (roughly Tier 3/Stage IIIA era) run the Cat C9 ACERT, an 8.8 L inline-six rated around 138 kW (185 hp) net. Later Tier 4 Interim/Final machines were updated to the Cat C9.3 ACERT, a 9.3 L inline-six rated around 153 kW (205 hp) net, which added a diesel particulate filter (DPF) and EGR-based emissions system. Operators of the newer C9.3 engines report more top-end issues than the earlier generation, with several threads tracing engine damage back to the high-pressure fuel injection pump, occasionally severe enough that a seized pump wiped out the front gear train; carbon buildup linked to the EGR circuit is cited as a contributing factor. A separate documented issue on C9.3-equipped machines is a cylinder misfire at low idle (below roughly 1500 rpm) that clears above that speed, associated with valve-train (cam/lifter) clearance problems. Because DPF regeneration is fuel-burn dependent rather than pure hours, owners report the filter eventually needs to be pulled and cleaned of accumulated ash (soot burns off in regen, ash does not), commonly discussed as happening somewhere in the neighborhood of a few thousand hours, though this varies by duty cycle and configuration.
What undercarriage wear patterns are typical, and does XL vs LGP configuration matter?
The D6T is offered in XL, LGP (low ground pressure), and other track-gauge/shoe configurations, and forum and dealer guidance treat undercarriage as the largest lifetime cost center on the machine, ahead of engine or hydraulics. The D6T's elevated-sprocket design is generally credited with isolating the final drives and steering components from direct ground impact compared to older low-drive dozers, but shoe and link wear still tracks heavily with application: high-impact, rocky, or abrasive ground accelerates bushing and pin wear regardless of XL vs LGP, while cast/wide LGP shoes are explicitly not recommended for high-impact or highly abrasive conditions. Practical inspection guidance repeated across sources includes measuring pitch elongation across several track links and pins (with the track pulled tight) against OEM wear charts, checking sprocket tooth tips for wear indicating chain slippage, watching rollers for flat spots or seal leaks, and checking the frame and tensioner areas for cracking. Bottom line from the community: undercarriage life varies enormously by ground condition and operator technique, so hour-based rules of thumb are far less reliable than a physical wear measurement.
What electrical and sensor issues come up most often on the D6T?
Recurring forum threads describe the D6T throwing multiple diagnostic codes at once, and the common troubleshooting lesson is that one upstream sensor failure can cascade into several unrelated-looking faults. One documented case involved an atmospheric pressure sensor failure that threw off the calibration the ECM uses for other sensors, producing a batch of secondary codes that looked like unrelated failures until the root sensor was replaced. Blade control issues are also frequently sensor-related: low-voltage codes on the lift and tilt position sensors built into the blade control handle have been tied to simultaneous loss of blade hydraulic function, not just a display fault. A general FMI 02 ('data erratic/intermittent/incorrect') code is described as being as likely to be a corroded, damp, or loose connector as a failed sensor itself, so cleaning and inspecting ECM/harness connectors is a standard first step before condemning a sensor. Operators note the D6T's electronics are a significant step up in capability from the R-series machines it replaced, which is generally seen as a net positive but does mean more code volume and a steeper learning curve for in-house diagnosis.
What causes slow or inconsistent blade lift/tilt response on the D6T?
Owners troubleshooting sluggish blade lift or tilt most often point first to the pilot hydraulic system rather than the main lift/tilt cylinders themselves: full pilot pressure is needed to actuate tilt and to lower/feather the blade smoothly, and a weak accumulator charge or a faulty pilot relief/pressure-reducing valve is repeatedly cited as the root cause of blade drop or lazy feathering. Beyond the pilot circuit, worn or internally leaking main control valve spools are described as a classic cause of generic slow lift/lower response, along with low pump output or a tripped relief pressure suggesting a supply-side pump problem. As noted above, low-voltage faults on the blade handle's lift/tilt position sensors can also present as a hydraulic fault even though the root cause is electrical, so a proper diagnosis checks both the pilot pressure and the sensor signals before parts are replaced. Community consensus is that keeping hydraulic fluid clean and addressing small leaks early prevents most of these control-valve wear issues from developing in the first place.
Is there a known final drive weak point on the D6T, especially on steep-slope work?
Yes — this is one of the more specific complaints repeated in operator discussions. Multiple owners report final drives failing on D6Ts working sustained steep side-slopes (around a 2:1 grade cited in one thread), where the constant side angle pushes gear-case oil to one side and away from the opposite final drive's seals and gears. Operators attribute part of the issue to Caterpillar's use of a lighter-weight gear oil (cited as roughly 50-weight rather than the 90-weight used on earlier R-series machines) in the D6T final drives/steering compartment, reasoning that the thinner oil is more prone to working past seals under sustained one-sided loading — though exact viscosity grade and whether this applies across all D6T build configurations varies by source, so treat it as a reported field pattern rather than a confirmed universal spec. Because a final drive failure is a safety- and cost-critical event (loss of drive/steering on one side, potential for sudden loss of control on a slope), have your dealer verify final drive oil level, condition, and seal integrity — especially on machines with a history of steep side-hill work — before relying on the machine in that terrain again.
What should a buyer check when evaluating a used D6T?
Community buying guidance converges on a short list, in rough priority order. First, undercarriage: measure link/pin wear (pitch elongation) across a stretched section of track against OEM wear charts, check sprocket teeth for wear consistent with chain slip, inspect rollers and idlers for flat spots or seal weep, and look the frame over for cracking near welds and the track tensioner/recoil area — this is consistently flagged as the biggest cost center on any used dozer. Second, engine and emissions: check for blow-by/coolant contamination as a basic health check, confirm engine model (C9 vs C9.3 ACERT) against the year, and ask about DPF/DOC condition and regeneration history on Tier 4 units, since ash-loaded filters and derates are a known pattern on higher-hour Tier 4 machines. Third, powertrain: verify the transmission/torque divider and steering clutch oil has a documented change history (given how often clutch-pack failure is tied to skipped services) and test the machine through all direction/gear changes for hesitation, flare, or stalling under load. Fourth, hydraulics: cycle the blade through lift, tilt, and angle functions checking for lazy or inconsistent response, and pull codes to check for stored blade-handle sensor faults. Finally, ask specifically about steep-slope duty cycle history given the reported final drive wear pattern on side-hill work. As with any used-equipment purchase, have your dealer (or an independent Cat-experienced tech) verify undercarriage measurements, hydraulic pressures, and any stored fault codes with proper gauges and diagnostic software before finalizing a purchase.
