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

SystemCapacityRecommended fluid
Engine crankcase (with filter)Not documented for this exact serial range — verify with your dealerKomatsu 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 systemNot documented for this exact serial range — verify with your dealerKomatsu 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 tankNot documented for this exact serial range — verify with your dealerAutomotive 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/tankNo 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 specsNot 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.

What D50P-17(S/N 80001-UP) owners discuss

What engine powers the D50P-17 (S/N 80001-UP) and what are its key performance characteristics?
The D50P-17 uses the 6D125-1 mechanical, naturally aspirated inline-six diesel engine. It produces 92 kW (124 hp) gross power at 1750 rpm. As a mechanical engine, it lacks electronic cold-start assist beyond glow plugs or ether aids. In cold conditions, check coolant concentration and battery capacity closely. In hot, dusty environments, shorten air cleaner service intervals and keep the radiator core clear of debris. Fuel injection timing must be checked by aligning the timing line on the fuel injection pump with the line on the coupling. If lines are not aligned, loosen the bolt in the oblong hole, move the coupling to align the lines, then tighten the bolt.
How does the D50P-17's hydraulic system behave under load, and what are common failure patterns?
The D50P-17 utilizes a hydraulic system where shared supply issues affect all functions simultaneously. If all hydraulic functions become slow, check the hydraulic oil level, correct hydraulic oil specification (Komatsu HO or equivalent), hydraulic filters, engine RPM under load, and hydraulic oil temperature. If the machine works cold but becomes weak when hot, this indicates excessive internal leakage that becomes noticeable as viscosity decreases. Suspect hydraulic pump wear, main control valve leakage, or cylinder leakage. If only one function is slow, investigate the specific cylinder, control-valve spool, or hose restriction. The Komatsu line is generally reliable, but pump failure can lead to engine damage if not addressed promptly.
What are the typical undercarriage and wear patterns for the D50P-17 compared to the standard D50A-17?
The D50P-17 is a low-ground-pressure (LGP) swamp variant with a wider track and LGP undercarriage geometry, making it heavier than the standard D50A-17. The standard D50A-17 weighs approximately 12,240 kg (27,000 lb), while the D50P-17 operating weight is 14,400 kg (31,747 lb). The D50P-17 undercarriage features 49 shoes per side, 8 track rollers per side, and 2 carrier rollers per side. Track tension and undercarriage checks differ from the standard D50A-17 due to the wider, lower-ground-pressure track. Components like bushings, bearings, and track pads are subjected to significant wear. Worn-out bushings can lead to noise and vibration, while worn bearings may cause premature failure of the tracks. have your dealer verify the track tension specifications for the LGP configuration.
What are the common electrical and sensor issues reported for this machine series?
Komatsu machines rely heavily on electronic control systems; a single faulty sensor or unstable power supply can trigger multiple warning signals. Owners often report intermittent starting, dashboard failure, or machines that randomly shut down. If the display monitor quits working, check the power wire from the fuse box to the monitor for voltage (approximately 24 volts). If the engine cranks and runs but will not rev to full RPM, check the throttle response circuit and safety or neutral-start inputs. A battery can show acceptable voltage until the starter is loaded; if the display dims heavily during starting, perform a proper load and voltage-drop test before ordering a starter.
What should be checked when buying a used D50P-17 (S/N 80001-UP)?
Verify the exact serial-prefix specification sheet and installed attachment package, as weight, reach, and fuel use vary by configuration. Check track tension on both sides and look for mud or debris packed into the undercarriage. Inspect the radiator core, hydraulic oil cooler, and charge-air cooler for debris packed between heat exchangers. Test the machine cold and hot to identify hydraulic weakness that appears only at operating temperature. Check the fuel injection timing alignment. Verify engine and chassis grounds and the main starter cable. Check the fuel level, fuel quality, fuel filters, and water separator. Inspect the cooling system for coolant expulsion or high pressure shortly after a cold start.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
