Komatsu D31P-16(S/N 25001-UP (Straight Tilt Dozer))
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D31P-16 (S/N 25001-UP) is a compact crawler dozer designed for utility earthmoving. This straight tilt configuration features a hydrostatic (HS) transmission with three forward and three reverse gears. The machine is powered by the Komatsu 4D 105-3, a 4-cylinder engine delivering 63 hp (47.0 kW) at 2350 rpm. Operating within the 14,771 lb (6,700 kg) weight class, it is engineered for tasks requiring low ground pressure and high maneuverability.
Across the D31 series, transitions between dash-numbers signify changes in engine emissions tiers and hydraulic refinements. The D31P-16 remains a significant unit in the used market due to its robust 4D 105-3 engine and hydrostatic drive, which simplifies operation in tight spaces. For parts sourcing and maintenance, identifying the specific serial range (25001-UP) is critical, as configurations for blade type and undercarriage width vary between different D31 series iterations.

Servicing the D31P-16(S/N 25001-UP (Straight Tilt Dozer)) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor hydraulic oil cleanliness to protect the hydrostatic transmission. Regularly sample engine oil to detect 4D 105-3 internal wear. Ensure hydraulic tank levels are maintained to prevent air ingestion in the steering valve. Use Komatsu-specified fluids to maintain correct viscosity and cooling system protection. Analyze fuel filter debris for signs of contamination that could impact the 264.3 cu in displacement engine performance.
Corrective & Common Repairs
Address steering clutch issues by inspecting brake band adjustments and yoke bearings if one-sided pulling occurs. If hydraulic return flow is restricted, inspect the transmission screen filter for blockages. Check steering valve pressure and return lines if pedal resistance or clutch engagement feels inconsistent. Monitor for leaks in the hydraulic hoses feeding the clutch caliper/slave cylinders to prevent loss of steering control.
Overhaul & Rebuild Points
Plan for undercarriage rebuilds when track pitch increases significantly due to pin and bushing wear. During engine overhauls, focus on the 4-cylinder head and injection pump components. Evaluate the hydrostatic transmission for internal wear if forward/reverse speeds deviate from factory specs. Inspect the straight tilt blade frame and hydraulic cylinders for structural fatigue or seal degradation during major component disassembly.
Seasonal & Environment Servicing
In high-dust environments, clean the air pre-cleaner daily to prevent engine choking. During winter operations, ensure the cooling system fluid is rated for low temperatures and check for radiator blockages. In muddy conditions, clear debris from the 6 track rollers per side and the idler area to prevent undercarriage buildup. Regularly inspect dust seals between track links and pins to maintain effective protection against abrasive soil.

D31P-16(S/N 25001-UP (Straight Tilt Dozer)) serial number reference
The serial number plate is typically located on the front frame casting, near the operator's left side or radiator support. Match the model designation (D31P-16) and serial range (25001-UP) on the plate to the parts catalog or service manual. Verify the 'Straight Tilt Dozer' configuration if the plate includes a specific variant code.
| Prefix | Identifies | Notes |
|---|---|---|
| D | D31P-16 (Straight Tilt Dozer) | The 'D' prefix identifies the crawler dozer family. The '31' denotes the size class. The '-16' indicates the generation. The 'P' suffix and 'Straight Tilt Dozer' designation specify the blade configuration. Serial numbers 25001 and up apply to this model. |
Frequently asked questions
What engine is used in the D31P-16?
The machine is equipped with a Komatsu 4D 105-3, a 4-cylinder engine with a displacement of 264.3 cu in (4.3 L).
What is the operating weight of this model?
The operating weight is approximately 14,771 lb (6,700 kg), though specific values may vary slightly by configuration/series.
What machine replaced the D31P-16?
The D31P-16 was part of a lineage that includes later generations such as the D31P-17 and D31P-20.
What D31P-16(S/N 25001-UP (Straight Tilt Dozer)) owners discuss
What are the common causes of erratic steering or loss of steering function on a D31P-16?
Steering issues often stem from air locks in hydraulic circuits, which can be resolved by cycling valves or releasing pressure. Mechanical faults include worn yoke bearings, worn pivot point bushings, or misadjusted brake linkage. Additionally, debris in the steering valve or leaking clutch release piston O-rings can interrupt oil flow to the clutch pistons.
What hydraulic issues are frequently reported regarding the blade tilt mechanism?
Blade tilt failure on the left side is often linked to a broken or shortened tilt rod (sometimes due to previous welding/modifications) or failed piston seals in the angle cylinder. Users also report that rotted or broken cooler lines within the belly pan can restrict oil flow, negatively impacting transmission and steering performance.
What engine-related startup behavior should be expected from this series?
Some operators report a 'no-crank' condition where the engine may stall upon shutdown and refuse to restart; in such cases, working the throttle back and enough may allow cranking. The D31P-16 utilizes a 4D105-3 engine with 4 cylinders and 264.3 cu in (4.3 L) displacement.
What are the typical undercarriage wear patterns or maintenance considerations for this model?
The machine features 6 track rollers per side and a standard shoe size of approximately 23.7 in (60 cm). To prevent abrasive dirt or mud from entering pin-to-bushing clearances and increasing link pitch, ensure the Komatsu dust seals between track links and pins are intact.
What should be checked regarding the transmission and hydraulic oil systems?
Check for air intake at the transmission pump shaft seals, as this can cause frothy oil and poor hydraulics. If steering is weak despite proper pressure readings (e.g., 2-70 psi), inspect the screen filter in the hydro shift transmission for cleanliness. The hydraulic oil tank capacity is approximately 45 L (12 U.S. Gal).
What is the most critical check to perform when buying a used D31P-16?
