Komatsu D20P-6(S/N 60001-UP (Straight Tilt Dozer))
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D20P-6 (S/N 60001-UP) is a compact crawler dozer in the approximately 4-metric-ton class. This series features a naturally aspirated 4D95S-W1 four-cylinder diesel engine producing 40 hp (29.8 kW) at 2450 rpm, with an operating weight ranging from 8465.8 lb (3840 kg) to 8686.3 lb (3940 kg) depending on configuration. The machine is equipped with a direct drive transmission offering 3 forward and 2 reverse gears. Common configurations for this serial range include the Straight Tilt or Power Angle Tilt (PAT) blade setups.
The -6 generation represents a specific era of Komatsu's small crawler development, preceding the more modern -7 and -bl8 series which introduced different emissions standards and telematics. This machine remains significant in the used parts market due to its mechanical simplicity, featuring dry clutches and brakes rather than oil-bathed systems. Its robust 4D95S engine and straightforward hydraulic architecture make it a highly sought-after unit for light earthmoving, landscaping, and utility applications where ease of repair is prioritized.

Servicing the D20P-6(S/N 60001-UP (Straight Tilt Dozer)) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor the 4D95S engine oil and hydraulic fluids regularly. Analyze oil samples for metal particulates to detect early wear in the 4-cylinder block or hydraulic pump. Check transmission fluid clarity to prevent clutch pack degradation. Ensure coolant levels are maintained to prevent overheating of the naturally aspirated diesel unit. Regular inspection of air intake prevents dust contamination within the engine's 164.2 cu in displacement cylinders.
Corrective & Common Repairs
Address hydraulic cylinder seal leaks immediately to prevent blade leak-down or reduced lift force. Inspect steering clutches and brakes if uneven engagement or sticking occurs, as these dry systems are prone to wear. Monitor the alternator and starter bendix for electrical failures. If steering loss is detected in warm operating conditions, investigate the steering pump for internal leakage or hydraulic pressure drops within the control valve.
Overhaul & Rebuild Points
Plan engine overhauls when compression drops or significant smoke appears, focusing on the 4D95S-W1 components. During undercarriage rebuilds, evaluate the wear limits of drive sprockets and track rollers. Inspect the transmission for clutch pack replacement if forward/reverse transitions become sluggish. Rebuild hydraulic control valves and angle selector valves if blade response becomes inconsistent or if PAT cylinders fail to maintain position.
Seasonal & Environment Servicing
In cold weather, ensure the engine is warmed thoroughly before applying high load to prevent stress on the 4-cylinder block. During dusty summer operations, increase air filter inspection frequency to prevent engine choking. In wet or muddy environments, clean the undercarriage thoroughly to prevent mud buildup from affecting track pitch and tension. Check all grease points frequently to combat abrasive grit ingress into pivot pins.

D20P-6(S/N 60001-UP (Straight Tilt Dozer)) attachments & work tools
Blades
Standard blade width is 7.2 ft (2170 mm) with a height of 23.3 in (590 mm). Power Angle Tilt (PAT) configurations are available for the D20P-6A variant, featuring a wider 8.4 ft (2560 mm) width and 23.3 in (590 mm) height.
Rippers
Single-shank rear ripper or scarifier is an available option for this model. Multi-shank parallelogram rippers are not offered for this machine class.
Winches
No factory-cataloged winch options are documented; however, aftermarket hydraulic units may be integrated by tapping into the blade tilt or angle circuits via a diverter valve. Suitable units should match the ~3.9–4.1 t machine weight class.
Drawbars/counterweights
No factory-installed package is documented; rear-end configuration centers on the optional ripper or scarifier. Drawbar or counterweight solutions are considered aftermarket or dealer-fabricated.
Cab/ROPS guarding options
Standard configuration includes a fiberglass rain canopy. ROPS-certified steel canopies are an option for the -6 generation, whereas they became standard starting with the -8 generation; no factory forestry-specific guarding package is listed.
Hydraulic arrangement notes
Front blade circuit operates via the main hydraulic control valve, with PAT configurations adding an angle cylinder and selector valve. There is no standard dedicated rear circuit for ripper or winch; rear attachments share the blade valve bank through a different configuration.

What D20P-6(S/N 60001-UP (Straight Tilt Dozer)) owners discuss
What are the common hydraulic steering symptoms on a warm Komatsu D20P-6?
Operators report left-side steering loss after approximately 20 minutes of operation. Symptoms may mimic engaged brakes or failed clutches. Troubleshooting should begin with checking hydraulic fluid levels and quality, as internal pump wear or leakage is a frequent cause.
What engine is installed in the Komatsu D20P-6 (S/N 60001-UP)?
The machine is powered by a naturally aspirated Komatsu 4D9sS-W-1 four-cylinder diesel engine. It provides gross power of approximately 29.8 kW (40 hp) at 2450 rpm with a displacement of 164.2 cu in (2.7 L).
What are the typical undercarriage wear points for this dozer?
Primary wear points include the rear drive sprockets and track rollers. Users should inspect sprocket teeth for pointed profiles, which indicates the wear limit has been exceeded. Track sag should be checked at the midpoint between the idler and sprocket.
Are there known electrical or sensor issues with this specific series?
This generation lacks an Engine Control Module (ECM) or electronic sensors. Common electrical failures are limited to mechanical components such as a failing alternator, worn starter bendix/ring gear, or charging diode faults.
What should be inspected regarding the steering clutch and brake system?
The D20P-6 utilizes dry clutches and brakes rather than oil-bathed systems. These components are prone to sticking or uneven engagement after long periods of idling. Brake band adjustments are accessed from the rear of the steering housing.
What should be checked when buying a used Komatsu D20P-6 (S/N 60001-UP)?
Verify the blade type and any attached implements. Check all fluids for proper levels and signs of water contamination. Inspect the air filter for dirt or nesting, check track shoes and rollers for wear, and cycle the steering levers to check for clutch/brake irregularities. Check for blade leak-down and verify charging output. Have your dealer verify steering clutch and brake function.
