Komatsu D21P-6(S/N 60001-UP (Straight Tilt Dozer))
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D21P-6 (S/N 60001-UP) is a compact crawler tractor designed for earthmoving and landscaping. This straight tilt dozer configuration features the 4D95S-W1 engine, delivering 3035 kW (4070 hp) gross power at 40 rpm. The machine operates in the 4070 kg (8972.9 lb) weight class and is part of the Dash-6 generation. Standard configurations include a 2170 mm (7.2 ft) wide blade and a DD transmission type with 3 forward and 2 reverse gears.
Across its production life, the D21 series evolved through various dash-number generations, transitioning from pre-Tier 3 to later emissions standards like Tier 3/Stage IIIA in Dash-7 models. The D21P-6 remains a significant unit in the used market due to its robust engine and reliable undercarriage design. Maintenance of the track gauge (1310 mm / 4.3 ft) and shoe size (510 mm / 20.08 in) is critical for preserving machine value and operational efficiency.

Servicing the D21P-6(S/N 60001-UP (Straight Tilt Dozer)) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil using 10w/30 or 15w/40 grades to detect internal wear. Regularly sample hydraulic oil (ISO HLP 32, 46, or 68) for particulate contamination. Track transmission fluid levels and inspect for thermal degradation. Use periodic oil analysis to identify early signs of engine component fatigue or fuel dilution before they lead to catastrophic failure.
Corrective & Common Repairs
Address steering difficulties by inspecting the steering clutches and brakes, as worn components can cause uneven turning. If black smoke appears during operation, investigate the injector feed pump or fuel system for air leaks. Monitor hydraulic pressure buildup; sudden changes may indicate faulty relief valves or alternator voltage fluctuations affecting hydraulic control.
Overhaul & Rebuild Points
Plan major engine overhauls around the 2000-hour valve adjustment milestone. Focus on inspecting the 4D95S-W1 engine block and cylinder heads for compression loss. During transmission rebuilds, evaluate the DD type gear set and clutch plates. For undercarriage reconstruction, assess the wear on all 37 shoes per side and the 5 track rollers per side to determine replacement necessity.
Seasonal & Environment Servicing
In dusty environments, prioritize frequent air filter maintenance and radiator cleaning to prevent overheating. During cold operations, ensure use of appropriate engine oil viscosity and check coolant for proper antifreeze concentration (Red OAT or Blue Concentrate). Inspect the 360 mm (1.19 ft) ground clearance for debris buildup that could impede movement in muddy or snow-covered terrain.

D21P-6(S/N 60001-UP (Straight Tilt Dozer)) serial number reference
The serial number plate is located on the front frame casting, typically on the operator's left side near the radiator support. To read the prefix, identify the first three characters of the machine's identification string on the chassis plate or emissions plate.
| Prefix | Identifies | Notes |
|---|---|---|
| Not explicitly documented | D21P-6 (S/N 60001-UP) | The specific PIN prefix for the D21P-6 (S/N 60001-UP) is not provided in available technical documentation. Standard Komatsu serial formats for this era typically utilize 4 to 7 digits or a 17-character ISO PIN for export models. |
Frequently asked questions
What engine is installed in the D21P-6?
The machine is powered by a Komatsu 4D95S-W1, 4-cylinder engine with a displacement of 164.2 cu in (2.7 L).
What is the operating weight of this model?
The standard operating weight for the D21P-6 is approximately 8972.9 lb (4070 kg).
What machine replaced the D21P-6?
The D21 series progressed through subsequent generations, including the D21P-7 and later Dash-8 models.
What D21P-6(S/N 60001-UP (Straight Tilt Dozer)) owners discuss
What are the common steering issues reported for the D21P-6?
Operators have reported instances of poor left-side steering response. In some cases, the machine may only turn effectively when not under load. Additionally, there are reports of steering clutches and brakes rusting together or failing, which directly impacts steering functionality.
What engine model is used in the Komatsu D21P-6 (S/N 60001-UP)?
The machine is equipped with a Komatsu 4D95S-W1 engine, which is a 4-cylinder diesel engine with a displacement of 2.7 L (164.2 cu in).
What hydraulic behavior should be monitored on this model?
Users have noted significant hydraulic pressure buildup within the reservoir when the machine has been sitting for a period of time and the cap is removed.
Are there known fuel system or power issues with the D21P-6 engine?
Failures in the fuel injector feed pump have been linked to rough running conditions and the production of black smoke. Some operators also report a general lack of power during heavy tasks, such as pushing dirt loads.
What are the standard undercarriage specifications for this machine?
The undercarriage features 37 shoes per side with a standard shoe size 510 mm (20.08 in). The track pitch is 135 mm (5.32 in) and there are 5 track rollers per side.
What should be checked when purchasing a used D21P-6?
Verify the serial number on the front frame casting against the riveted plate on the machine; any mismatch is a primary signal of stolen equipment. Additionally, check the engine serial number stamped on the block (typically near the injection pump) to ensure it matches maintenance records, as re-engined machines will have different numbers.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
