Komatsu D85P-21(S/N 3001-3688-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D85P-21 is a crawler tractor designed for heavy-duty earthmoving, land clearing, and grading. This machine belongs to the D-series and features a 6-cylinder S6D125E turbocharged engine producing 228 hp (170 kW). Operating within a weight range of approximately 58,841 lb (26,690 kg) to 60,186 lb (27.3 t), it is configured with a wide track width for low ground pressure applications. The series includes various configurations such as the D85A and D85E variants.
Across generations, the D85P-21 represents a stable era of Komatsu engineering before the transition to more complex emission-controlled engines like the S6D12-2. This specific serial range (3001-3688-UP) remains highly relevant in the used parts and machinery market due to its mechanical reliability and the availability of robust components for the S6D125E powertrain. Its durability makes it a primary choice for secondary applications where high-performance, low-maintenance crawler tractors are required.

Servicing the D85P-21(S/N 3001-3688-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil and hydraulic fluid for particulate contamination. Regularly check the 7.2 gal (27 L) engine oil capacity and 27 gal (102 L) hydraulic reservoir for degradation. Analyze transmission fluid to detect metal shavings that indicate gear wear. Use periodic sampling of the 20.9 gal (79 L) cooling system to prevent internal corrosion within the S6D125E radiator circuit.
Corrective & Common Repairs
Address hydraulic pressure drops by inspecting the gear type pump and relief valve, which should maintain 2773.6 psi (191.2 bar). If the machine loses power in low gears, inspect the Torqflow transmission for clutch slippage. Monitor track shoe wear and pitch adjustments to prevent excessive undercarriage vibration. Replace worn hydraulic hoses if leaks appear near the blade lift cylinders.
Overhaul & Rebuild Points
Plan engine overhauls when compression drops in the 930.1 cu in (15.2 L) S6D125E block. Evaluate final drive rebuilds if oil levels in the 10.9 gal (41 L) housings drop due to seal failure. Monitor undercarriage components, specifically the 8 track rollers per side and 45 shoes per side, for terminal wear. Rebuild hydraulic pumps when flow capacity falls below 51.3 gpm (194 L/min).
Seasonal & Environment Servicing
In dusty environments, increase frequency of air cleaner inspections to protect the turbocharger. During cold operations, ensure the 24 V electrical system and battery connections are free of corrosion. In high-molar areas, clean the undercarriage thoroughly to prevent mud buildup on the 8.51 in (216 mm) track pitch. Check radiator fins frequently to maintain optimal cooling flow.

D85P-21(S/N 3001-3688-UP) serial number reference
The serial plate is located on the front frame casting, typically on the operator's left side near the radiator support. For export machines, a 17-character ISO PIN may also be found on the emissions/export plate near the engine bay. Read the model prefix to identify the machine family and the digits following it to determine the build sequence.
| Prefix | Identifies | Notes |
|---|---|---|
| D | D85P-21 | Identifies the crawler dozer family. The numeric value indicates the size class. The suffix 'P' denotes the LGP (Low Ground Pressure) configuration. Serial range 3001 to 3eler is associated with the S6D125-1 engine series. Machines from serial number 3689 and up utilize the S6D125E-2 emission-compliant engine. |
Frequently asked questions
What engine is installed in the D85P-21?
The machine is powered by a Komatsu S6D125E 6-cylinder turbocharged diesel engine with a displacement of 930.1 cu in (15.2 L).
What is the operating weight of this bulldozer?
The operating weight varies by configuration and serial range, typically documented between 58,841.4 lb (26,690 kg) and 60,186 lb (27.3 t).
What model replaced the D85P-21?
The D85 series evolved into later generations such as the D85EX-18, which utilized different engine technologies and automated systems.
What D85P-21(S/N 3001-3688-UP) owners discuss
What are the known transmission and drivetrain issues reported for this machine?
Operators have reported instances where the machine stops pulling in low gear, both forward and reverse, once the unit reaches operating temperature. The transmission type is TF (Torqflow). The system features 3 forward gears and 3 reverse gears.
What engine model is used in the D85P-21 (S/N 3001-3688-UP) and what are its primary specs?
The machine utilizes the S6D125E turbocharged engine. It is a 6-cylinder engine with a displacement of approximately 930.1 cu in (15,242 cc). Key performance metrics include gross power of 228 hp (170 kW) at 2000 rpm and maximum torque of 737.3 lb-ft (999.6 Nm) at 1400 rpm.
What undercarriage wear patterns or specifications should be monitored?
Typical monitoring involves checking the 45 shoes per side and the 8 track rollers per side. The track pitch is approximately 8.51 in (21.6 cm) to 8.6 in (21.8 cm), and the standard shoe size is roughly 35.83 in (91 cm) to 35.9 in (91.2 cm). Excessive wear on carrier rollers (2 per side) or track tensioning system malfunctions are common maintenance concerns.
What hydraulic system behaviors or specifications define this model?
The machine uses a gear-type pump in a closed-center, load-sensing configuration. The pump flow capacity is approximately 51.3 gpm (194.2 lpm). Relief valve pressure is rated at 2773.6 psi (191.2 bar). Common issues include hydraulic system leaks or failures.
What electrical system components are standard on this series?
The machine operates on a 24V electrical system with an alternator-regulated type. The battery capacity is rated at 12v / 150 ah, and the alternator provides 24v / 50a output. Common issues include dead batteries or faulty wiring.
What should be checked when buying a used D85P-21 (S/N 3001-3688-UP)?
Inspect the engine for overheating and check the transmission for slipping or failure to engage, especially after the machine warms up. Verify the condition of the undercarriage components, specifically track tensioning and roller wear. Check hydraulic systems for leaks and inspect electrical wiring for faults. Have your dealer verify all safety-critical repairs and component integrity.
