Komatsu D39PX-21A(S/N 1501-UP (Overseas Version))
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D39PX-21A (S/N 1501-up, overseas version) is a small-class crawler dozer built for grading, land-clearing, and general earthmoving where flotation and precision matter as much as raw pushing power. It runs the Komatsu SAA4D102E-2, a turbocharged, air-to-air aftercooled four-cylinder diesel rated at roughly 71 kW (95 hp) at 2200 rpm, paired with Komatsu's KOMSTAT II dual-path hydrostatic transmission. Operating weight in the PX (wide-gauge, low ground pressure) configuration runs around 8,900 kg (19,620 lb), heavier than the narrower-gauge EX sibling built on the same chassis. This 21-series generation followed Komatsu's earlier torque-converter D39 dozers and was itself succeeded by the D39PX-22 generation. Buyers could spec straight or angle blades, canopy or enclosed cab, and standard or wide track shoes depending on jobsite conditions.
The move from the original 1001-1499 D39PX-21 build to the 1501-up 'A' production run carried forward running changes to the HST drive and cooling circuit rather than a full model redesign; the OMM and shop manual for this range cover the D39EX-21, D39PX-21, and their smaller D31 and D37 platform-mates as one family. Komatsu later stepped the D39 line up to the Tier 3 D39PX-22 generation, then Tier 4 Final D39PX-23 and current D39PX-24/-24i models with factory grade-control options. On today's used and parts market, D39PX-21A units remain popular as affordable, mechanically simple grading dozers: no steering clutches or brakes to overhaul, straightforward final drives, and a parts base shared across the whole 21-series family, though buyers should budget for HST pump and travel motor wear on higher-hour machines.

D39PX-21A(S/N 1501-UP (Overseas Version)) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | Refill 12.5 L (3.3 US gal); total specified system capacity incl. filter and piping 14 L (3.7 US gal) | Komatsu Genuine engine oil, API classification CD (CE also acceptable) selected by ambient temperature: SAE30 for 0 to 40°C, SAE10W for -20 to 10°C, SAE10W-30 for -20 to 40°C, SAE15W-40 for -15 to 40°C. Komatsu-branded grades: EO10-CD, EO30-CD, EO10-30CD, EO15-40CD. If diesel sulphur content runs 0.5-1.0%, cut the oil change interval in half; above 1.0%, cut it to a quarter. |
| Cooling system (incl. sub-tank) | 32 L (8.5 US gal) - this D39 series figure; the D31/D37-21 series covered in the same OMM book lists 27 L for the same position, so this is a series-specific split, not a shared number | Water plus permanent-type antifreeze (ethylene glycol base with corrosion inhibitor and antifoam agent), effective down to -30°C, max 40°C. Komatsu-branded coolant: AF-ACL or AF-PTL permanent type; AF-PT one-season winter type only if permanent antifreeze is unavailable. Do not mix antifreeze types. |
| Fuel tank | 165 L (43.6 US gal) - common figure across the D31/D37/D39-21 OMM book, not split by series | Diesel fuel per ASTM D975 No.2 for -20 to 40°C ambient; switch to ASTM D975 No.1 winter grade in colder climates (down to about -30°C). |
| Transmission/powertrain (HSS dual-path hydrostatic transmission) | No separate reservoir - shares the main hydraulic tank (see Hydraulic system/tank row). This machine uses a KOMSTAT dual-path HSS hydrostatic transmission, not a powershift transmission with separate bevel gear/steering clutch compartments, so the OMM does not split those out as distinct fluid rows | Same Komatsu Genuine engine oil grades as the crankcase (SAE30/SAE10W/SAE10W-30/SAE15W-40, API CD) - the OMM groups the hydraulic system, HSS charge-pump circuit, and idlers all under its "engine oil" fluid category rather than a distinct hydraulic or gear-oil spec. |
| Final drive case (each side) | 3.5 L (0.9 US gal) refill, each side | Same Komatsu Genuine engine oil grades as the crankcase (SAE30/SAE10W/SAE10W-30/SAE15W-40, API CD) per the OMM's reservoir/fluid-kind table, which ties final drive case to "engine oil," not gear oil. Note: the same manual's separate multi-brand cross-reference chart also lists a GL-4/GL-5 gear oil option (SAE80/90/140, Komatsu-branded GO90/GO140) that applies elsewhere in the book's model range - confirm which fluid kind is correct for this exact final drive before substituting. |
| Hydraulic system/tank | Refill 47 L (12.4 US gal) per the OMM fluid table for this D39 series. A hydraulic-tank oil-and-filter change procedure calls for about 44 L in practice. A separate general specified-capacity figure of 97 L (total oil including components and piping) also appears in the OMM but is not clearly broken out by series - treat 47 L as the reliable D39 refill figure and verify against your own machine before ordering bulk oil. | Komatsu Genuine engine oil (same spec as crankcase) - SAE30/SAE10W/SAE10W-30/SAE15W-40 by ambient temperature, API CD. No separate ISO-graded hydraulic oil is called out in this OMM for this chassis size. |
| Pivot shaft | Not listed as a separate reservoir in this OMM | Not documented for this model/serial range - the fluid chart in this OMM has no separate pivot-shaft or equalizer-bar oil compartment. Verify with a Komatsu distributor if your machine's equalizer/trunnion design needs separate service. |
| Grease (all fittings) | Not a filled-reservoir capacity - applied by grease gun at lubrication points until it purges from the joint | Lithium-base grease, NLGI No.2, OMM-rated for roughly -15 to 40°C. Komatsu Genuine Grease G2-LI (G2-LI-S low-temperature version for cold climates). Wipe off old purged grease after each greasing. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the D39PX-21A(S/N 1501-UP (Overseas Version)) beyond the schedule
Predictive Maintenance & Fluid Analysis
On the D39PX-21A, oil sampling matters most on the HST charge circuit and the SAA4D102E-2's turbocharger. Pull hydraulic/HST oil samples at every 250-hour interval and watch for fine metal, which signals charge pump or travel motor wear before a full loss of drive function occurs. Track coolant SCA/corrosion resistor condition alongside engine oil analysis, since the turbocharged four-cylinder runs hot in continuous grading work. Log final drive oil condition each 1000-hour change to catch bearing wear early.
Corrective & Common Repairs
Most D39PX-21A downtime traces back to the KOMSTAT II hydrostatic drive: a clogged charge filter or low charge pressure can drop all hydraulic and steering function at once, even with clean-looking filter elements. Check charge pressure against factory spec before assuming a pump failure. Uneven track speed side-to-side points to a restricted flow port or a sticking control valve rather than a worn motor. Blade lift/tilt cylinder seal leaks and worn equalizer bar bushings are the other recurring wear items on this platform.
Overhaul & Rebuild Points
Major rebuild points on the D39PX-21A center on the HST pump-and-motor stack and the final drives. Each in-shoe-mounted travel motor pairs to a two-stage planetary final drive at the sprocket; plan a rebuild around bearing and seal wear once final drive oil analysis shows metal. The dual-path piston pumps and 3-speed variable travel motors should be bench-tested for internal leakage before a full teardown. Turbocharger overhaul (rotor play, bearing wear) and vibration damper inspection are standard companions to any engine-out rebuild.
Seasonal & Environment Servicing
In cold climates, use the correct viscosity engine oil and Komatsu's specified coolant concentration for the SAA4D102E-2 to protect cold-start turbocharger lubrication, and confirm block heater or ether-start function before winter dozing. In wet, muddy, or sandy jobsites, shorten the grease interval on blade linkage and track pins to every 10 hours instead of the standard 250, and clean the radiator/oil cooler/aftercooler fin pack more often since the low-ground-pressure PX undercarriage packs debris quickly against the belly guard.

| E05 | Governor motor (electronic throttle) system fault | Worn governor motor, poor connector contact, or aged harness affecting governor motor current draw on the electronically governed fuel injection pump | Check governor motor connector and harness for corrosion, then measure governor motor phase current against spec |
| E10 | Engine controller power supply failure / engine management system malfunction | Loss of clean battery power to the engine controller, blown fuse, or poor ground | Check engine controller power and ground circuits and fuses before condemning the controller |
| E11 | Engine control failure, engine output reduced to protect the engine | Engine controller detecting an internal fault or a sensor input out of range and derating power as a protective response | Retrieve the underlying engine sensor fault first, then clear and recheck after repair |
| E14 | Feedback system failure | A monitored actuator (fuel, hydraulic, or governor circuit) not returning the expected feedback signal to the controller | Check the wiring and connector of the affected feedback sensor/actuator circuit, then verify signal with a multimeter |
| E15 | Engine sensor malfunction (coolant temperature, fuel pressure, or oil pressure sensor) | Failed or out-of-range sensor reading, damaged sensor wiring, or connector corrosion | Check sensor wiring and connector, then test the sensor against Komatsu spec before replacing it |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
D39PX-21A(S/N 1501-UP (Overseas Version)) attachments & work tools
Blades
Komatsu does not use Caterpillar's S/SU/A blade letter system on this frame; the factory dozer blade is a 6-way PAT (power-angle-tilt) blade, roughly 2.6 m (8 ft 6 in) wide with about 1.7 m3 (2.2 yd3) capacity on this platform, though exact width/capacity varies with the standard vs. wide-gauge PX undercarriage fitted. No pitch-adjust (VPAT) blade is documented for this size class; Komatsu reserves the roll/pitch-adjust PAT option for the D61 frame and larger.
Rippers
Factory rear ripper on this platform is a hydraulically actuated single-shank, multi-pocket parallelogram ripper (5 shank pockets for adjustable penetration), controlled from a dedicated ripper circuit separate from blade hydraulics. A 3-shank multi-shank ripper (roughly 1.1 t bare) is built for the D39 frame by aftermarket ripper makers, but factory literature for this serial range centers on the single-shank unit — confirm multi-shank fitment with your dealer before ordering.
Winches
This machine sits in the roughly 13.6 t (30,000 lb) line-pull winch class. Both the Allied W3C and the Carco 30B cable/drum winches are built specifically to mount on the D31/D37/D39-21 and -21A KomStat I/II dozer frame, rear-mounted in place of/behind the drawbar, with power-in, power-out and freespool control.
Drawbars/counterweights
Published drawbar pull for this class is on the order of 108 kN (about 24,250 lbf); the machine uses a standard rear drawbar casting that also serves as the winch mounting point. No separate factory counterweight kit is documented in available literature for the -21A rear end beyond this drawbar — verify any heavier counterweight option with a dealer.
Cab/ROPS guarding
Komatsu's D39 line lists a forestry guarding package consisting of a front sweep plus rear and side screens fitted to the ROPS cab for branch/debris protection. A sealed, pressurized cab and undercarriage debris-guarding package (as cataloged on Komatsu's larger D85 WH waste-handler dozers) is not confirmed as a cataloged factory option for the D39PX-21A — treat as unverified for this model and confirm with your dealer if needed for waste-site duty.
Hydraulic arrangement
Travel is driven by the dual-path KomStat II HST, independent of the work-equipment hydraulics. Blade lift/angle/tilt cylinders for the 6-way PAT blade run on one hydraulic circuit, while the rear ripper's lift/tilt cylinders run on a separate ripper circuit; the machine's operation & maintenance manual documents ripper hydraulics ('Handling Hydraulic Ripper') as a distinct section from blade controls, and shares engine-driven pump capacity between the two front/rear tool circuits.

Frequently asked questions
What engine does the Komatsu D39PX-21A (S/N 1501-up, overseas version) use?
It is powered by the Komatsu SAA4D102E-2, a turbocharged, air-to-air aftercooled four-cylinder diesel rated at approximately 71 kW (95 hp) at 2200 rpm.
What is the operating weight of the D39PX-21A?
Around 8,900 kg (19,620 lb) in standard PX low-ground-pressure trim; actual weight varies with blade, ROPS/cab, and track shoe configuration.
What replaced the D39PX-21A in Komatsu's lineup?
Komatsu moved the D39 dozer line to the Tier 3 D39PX-22 generation, followed later by the Tier 4 Final D39PX-23 and current D39PX-24/-24i models.
What D39PX-21A(S/N 1501-UP (Overseas Version)) owners discuss
What's the drivetrain like on the D39PX-21A, and what powertrain issues come up most?
Dual-path hydrostatic drive (HST) - no gears to shift, pumps and drive motors set speed and direction directly. Owners report the machine runs strong and smooth in normal duty, but when trouble hits it's almost always a charge-pressure problem rather than a pump wearing out. Total loss of hydraulic function (blade dead, no forward/reverse, engine unaffected) traces most often to a weak or plugged charge pump or charge filter, since charge pressure is what shifts the spools on both the hystat and the work-equipment valves. A stall test and charge pressure check are the recommended first steps before assuming pump or motor failure. When a hystat does fail outright, rebuild cost runs high and metal can spread through the whole circuit, so oil sampling and frequent filter changes are the cheap insurance against a very expensive repair. Have your dealer verify charge pressure against factory spec before any teardown.
What engine does the D39PX-21A actually run, and are there any known quirks?
This serial range carries the Komatsu SAA4D102E-2, a water-cooled 4-cylinder diesel, turbocharged and air-to-air aftercooled, rated around 71 kW (95 hp) and built to Tier 2 / EU / Japan emissions for the overseas-market version (no diesel particulate filter or SCR to worry about on this generation). Reported quirks are mostly plumbing, not the block itself: heater valves feeding the cab core can gum up or stick over time (check for heat reaching the core if cab heat goes cold), and machines with land-clearing history pick up branches and debris in the radiator fins and hydraulic lines, which shows up later as overheating or restricted oil flow. The engine itself is generally described as one of the more trouble-free parts of the machine.
What undercarriage wear pattern should owners watch for?
Standard wear pattern for this swamp/wide-gauge dozer class: sprockets, track links, pins and bushings, rollers and idlers wear steadily, and owners are told to measure track sag rather than eyeball it. The single biggest driver of premature wear reported repeatedly is running the tracks too tight - it scores pins and bushings fast and is called a silent killer of undercarriage life, while tracks left too loose raise derailment risk and cause uneven wear. As pins and bushings wear, geometry shifts, so a track set correctly once can start showing tension symptoms again later - re-check on a schedule rather than a single setting. No public turn/replace wear table circulates for this exact serial range - have a tech measure current wear and compare against the factory spec sheet before budgeting for an undercarriage rebuild.
What electrical or sensor faults show up on this model?
This 1501-up "A" version moved to electronic pilot control in place of the earlier straight PPV (pilot pressure valve) hydraulic control used on the plain -21, so more of the machine's behavior runs through sensors and the monitor panel. The most-discussed fault is an E03 code that some 2009-model examples throw a minute or so after startup, with the machine otherwise running strong and never derating - a logged fault rather than an active shutdown. Treat "E03" as a starting point only: pull the actual sub-code from the monitor's service mode before diagnosing further, since the bare code alone does not point to a specific circuit. Separately, owners have chased a fuse that blows the instant the key goes to run, killing the whole dash, traced into the engine-compartment fuse panel wiring rather than a single failed sensor. Have your dealer verify the exact sub-code and wiring circuit before replacing parts on either symptom.
Are steering clutch, final drive, or brake problems common on this model?
Yes - this is one of the more consistent complaints across older Komatsu dozers in this class: steering clutch and brake wear shows up over time, and parts for that end of the machine price higher than on some competitors. Final drive trouble on the D39PX line tends to show up as one side not driving at all, and it's worth confirming whether the gear reduction itself is the problem or the hydraulic drive motor simply isn't being commanded to move before pulling anything apart. Owners who have gone ahead and rebuilt a final drive report no further trouble afterward, suggesting it's a wear item best addressed fully rather than patched. Given the steering and brake involvement, have your dealer verify the diagnosis and adjustment specs before the machine goes back into service.
What do owners and operators say about the D39PX-21A's overall reputation?
Consensus on this small dozer class from Komatsu is that it's tough and dependable in normal operation, and operators who run them like the hystat's smooth, precise feel compared to a geared transmission. The recurring complaint is nickel-and-dime in nature: small issues - electrical faults, valve or seal weeps, wear items - crop up more often than on some rival brands, and the machine is described as awkward to work on even though it needs the wrench less often overall. This is treated as a known trait of the model line, not a red flag unique to one unit.
What should I check before buying a used D39PX-21A?
Don't trust the hour meter alone - a machine can be worn out well ahead of its indicated hours if it was run hard or by a heavy-handed operator, and rental history is common for this size machine. Walk the undercarriage: sprockets, track chain, idlers (spin freely, no flat spots), rollers, and pads, looking for scoring that points to a history of over-tight track adjustment. Check the radiator core and hydraulic lines for old branch or debris damage if the machine has land-clearing history. Run every hydraulic function - blade, ripper if fitted, steering, forward and reverse in both directions - and check the monitor for any logged fault codes, not just what shows live on the dash. If the seller allows it, cut open the charge and hydraulic filters and look for metal. Given the cost of a hystat or final drive failure on this model, budget for a paid wear and pressure inspection before committing - have your dealer verify charge pressure, undercarriage wear measurements, and stored fault history as a condition of sale.
