Komatsu D50P-17(S/N 80001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D50P-17 is a medium-weight crawler dozer in the D50 series, designed for earthmoving and site preparation. It is powered by the Komatsu 6D125-1 inline-six diesel engine, rated at 124 hp gross power at 1750 rpm. The machine has an operating weight of 31,746.6 lb (14,400 kg) and features a direct drive transmission with 5 forward and 4 reverse gears. Standard configurations include a 11.6 ft wide by 37.6 in high blade, 49 shoes per side, and an undercarriage with 8 track rollers and 2 carrier rollers per side. The D50P-17 succeeded the D50P-16 and is part of the 17th generation of the D50 line, which itself evolved from the D50A-16 and D50P-15 predecessors.
The D50P-17 series introduced specific low-ground-pressure (LGP) undercarriage geometry and wider track shoes compared to the standard D50A-17, making it suitable for swampy or soft terrain. While the D50A-17 operates at a lighter weight, the D50P-17's heavier configuration provides better flotation. In the used and parts market, the D50P-17 remains relevant due to its robust mechanical engine and simple direct-drive powertrain, which are easier to service than modern electronic-heavy models. The 6D125-1 engine is widely supported, and the undercarriage components are interchangeable with other D50 series machines, ensuring long-term parts availability.

D50P-17(S/N 80001-UP) fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | Not documented for this exact serial range — verify with your dealer | Komatsu Genuine Diesel Engine Oil, SAE 15W-40 for normal ambient temperatures; SAE 10W-30 is the Komatsu-approved grade for colder climates. Equivalent cross-reference: Chevron Delo 400 series diesel engine oil built to the same Komatsu engine-oil specification. |
| Cooling system | Not documented for this exact serial range — verify with your dealer | Komatsu Super Coolant, supplied as concentrate mixed 50/50 with water (extended-life, all-season, anti-corrosion coolant). No separate winter/summer concentration split is called out beyond the standard 50/50 mix; use a higher concentrate ratio only for extreme cold per Komatsu's coolant freeze-protection chart. |
| Fuel tank | Not documented for this exact serial range — verify with your dealer | Automotive diesel fuel (ASTM D975 No. 2-D equivalent) for normal conditions; switch to a lighter No. 1-D-equivalent fuel in cold weather per Komatsu's ambient-temperature fuel guidance. Keep tank topped up at end of shift to reduce condensation. |
| Transmission/powertrain (powershift transmission + bevel gear/steering compartments) | Not separately published for this serial range. The D50A/P-17 uses a manually shifted spur-gear transmission (5 speeds forward, 4 reverse) with splash-type lubrication, sharing lubrication with the spiral bevel gear shaft and the wet multiple-disc steering clutch/band brake, per the factory specifications section; no standalone capacity figure was accessible. | Komatsu Powertrain & Micro Clutch Oil (drive-train fluid spec): SAE 10W in cold conditions, SAE 30 in normal/warm conditions. Equivalent cross-reference: Chevron Delo TorqForce in matching viscosity grade. |
| Final drives (each) | Not separately published for this serial range. Final drive is a 2-stage spur-gear reduction with splash-type lubrication per the factory specifications section; Komatsu shop literature for this chassis does not show it as an independently drained/filled compartment separate from the power train case in the data reviewed. | Komatsu Powertrain & Micro Clutch Oil, same grade as the power train case (SAE 10W cold / SAE 30 normal), unless the periodic maintenance chart calls out a dedicated final-drive fill point with Komatsu Gear Lubricant (SAE 80W-90 or 85W-140, API GL-5 class) - confirm which applies before servicing. |
| Hydraulic system/tank | No standalone hydraulic tank capacity is published; the hydraulic tank is integrated into the control valve assembly, so there is no separate reservoir on this chassis. | Komatsu hydraulic oil (46AW hydraulic fluid spec), ISO VG 46. Equivalent cross-reference: Chevron Rando HD or Delo TorqForce hydraulic-oil equivalents in ISO 46 grade. A Komatsu biodegradable hydraulic fluid option also exists under the same specification for environmentally sensitive sites. |
| Grease specs | Not applicable (grease points serviced per periodic lubrication schedule, not a fill volume). | Komatsu Lithium-base Grease EP2 (G2-LI), NLGI 2, general-purpose chassis grease for normal temperatures. Equivalent cross-reference: Chevron/Delo Grease ESI EP, NLGI 2. Use a lower-consistency (arctic-grade) NLGI 1 or 0.5 lithium grease in sustained sub-freezing climates per standard Komatsu cold-weather guidance. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the D50P-17(S/N 80001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize Komatsu KOWA fluid analysis at every 500-hour interval to monitor engine wear metals and hydraulic contamination. Check coolant SCA concentration at 500 hours to prevent liner cavitation in the 6D125-1 engine. Monitor transmission oil for viscosity changes and torque converter fluid condition at 1000 hours. Use KOMTRAX telematics to track load frequency and fuel burn rates, identifying inefficient operating cycles that accelerate fluid degradation. Regularly inspect hydraulic hose conditions for cracks or leaks during daily checks to prevent premature fluid loss and system contamination.
Corrective & Common Repairs
Address common D50P-17 issues by inspecting the final drive seals for leaks, which are frequent failure points in high-torque applications. Check the main clutch pump and steering pump for wear, as these components are critical for machine control. Replace fan belts if tension drops below specification to prevent engine overheating. Inspect the fuel injection pump timing lines for alignment, ensuring proper fuel delivery. Monitor the undercarriage for uneven shoe wear, particularly on the LGP tracks, and adjust track tension to prevent derailment or excessive roller wear.
Overhaul & Rebuild Points
Plan for major overhauls at 10,000 to 15,000 hours for the 6D125-1 engine, focusing on piston rings, cylinder liners, and valve seats. The direct drive transmission may require clutch plate replacement and gear inspection around 8,000 hours depending on duty cycles. Undercarriage components, including track rollers and carrier rollers, typically last 4,000 to 6,000 hours before significant wear necessitates replacement. Inspect the swing circle and final drive bearings for pitting or backlash during major service intervals to determine if rebuild kits are required.
Seasonal & Environment Servicing
In cold climates, verify coolant concentration and battery capacity before winter operations, as the mechanical engine lacks electronic cold-start assist. Use lower viscosity engine oil if temperatures drop significantly. In hot, dusty environments, shorten air filter service intervals and frequently clear debris from the radiator and oil cooler fins. For swamp or wet conditions, inspect the LGP undercarriage seals more frequently to prevent water intrusion. Ensure the ROPS/FOPS structure is intact and all safety lights and alarms function correctly in low-visibility conditions.
