Komatsu PC50UU-2(S/N 8001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PC50UU-2 is a compact, zero-tail-swing hydraulic excavator designed for utility and municipal work in tight spaces. Produced from approximately 1988 to 1995, it succeeded the PC50UU-1 and preceded the PC50MR-2 series. The machine features a 4D84-2GA or 4D88E-3 diesel engine, delivering roughly 38 to 39 horsepower. Operating weights vary by configuration, typically ranging from 5,100 kg to 5,300 kg (11,243 lb to 11,687 lb). It offers a two-piece offset boom option for precise digging in confined areas and is available in both canopy and cab configurations.
Across its generations, the PC50UU-2 introduced improved hydraulic efficiency and a more compact tail-swing radius compared to its predecessor, making it highly valued in the used market for urban infrastructure projects. Its significance today lies in its durability and the availability of aftermarket parts for its simple mechanical systems. The machine remains a staple in the rental and secondary market due to its ability to fit through standard gates and its low ground pressure, which minimizes surface damage on paved or sensitive job sites.

Servicing the PC50UU-2(S/N 8001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor KOWA fluid analysis results at every 500-hour interval to detect early wear in the hydraulic pump and engine components. Check the hydraulic oil temperature gauge during operation; excessive heat indicates cooler blockage or pump wear. Inspect the air filter restriction indicator daily; clogged filters reduce engine power and increase fuel consumption. Verify the coolant SCA concentration at 500 hours to prevent liner cavitation in the 4D84-2GA engine. Track fuel filter replacement intervals strictly to protect the high-pressure injection system.
Corrective & Common Repairs
Address hydraulic hose leaks promptly, as the PC50UU-2 uses high-pressure lines prone to abrasion against the frame. Replace worn track shoes and sprockets together to prevent uneven wear on the final drives. Check the swing bearing for play and noise, which indicates worn rollers or loose bolts. Inspect the travel motors for oil contamination, a common issue if hydraulic seals fail. Replace the hydraulic return filter if flow is restricted to maintain pump longevity. Verify the tension of the track chains to prevent derailment on steep grades.
Overhaul & Rebuild Points
Plan for a hydraulic pump overhaul when flow rates drop below specification or internal leakage causes slow cycle times. Inspect the engine cylinder liners for wear during major service intervals; the 4D84-2GA requires precise bore measurements for proper compression. Check the swing motor case drain for excessive flow, indicating internal seal failure. Evaluate the final drive planetary gears for pitting or spalling during the 2000-hour service. Replace the turbocharger if exhaust smoke indicates reduced boost pressure or oil consumption increases significantly.
Seasonal & Environment Servicing
In cold weather, drain the fuel water separator daily and use low-temperature fuel additives to prevent waxing. Check the coolant freeze protection level before winter to prevent block cracking. In dusty environments, clean the radiator and oil cooler fins daily to maintain engine temperature. Use the correct viscosity hydraulic oil for ambient temperatures to ensure smooth valve operation. Inspect the cab heater and defroster functionality for operator comfort and visibility. Store the machine in a dry location to prevent rust on exposed hydraulic cylinders and electrical connections.

PC50UU-2(S/N 8001-UP) serial number reference
The serial number plate is riveted to the right-hand side of the cab on the lower frame, typically just behind the front idler or beneath the operator's window. The prefix is the first four digits of the serial number stamped on this plate or directly into the chassis frame casting.

Frequently asked questions
What engine does the PC50UU-2 (S/N 8001-UP) use?
The PC50UU-2 (S/N 8001-UP) is equipped with either the Komatsu 4D84-2GA or the 4D88E-3 diesel engine, depending on the specific production date and regional specification.
What is the operating weight of the PC50UU-2?
The operating weight varies by configuration, typically ranging from 5,100 kg to 5,300 kg (11,243 lb to 11,687 lb).
What model replaced the PC50UU-2?
The PC50UU-2 was succeeded by the PC50MR-2 series, which introduced updated emissions compliance and modernized hydraulic systems.
What PC50UU-2(S/N 8001-UP) owners discuss
What are the common hydraulic behaviors reported for the PC50UU-2 when the system warms up?
Operators report that boom up and stick-in functions slow significantly or barely work when the hydraulic oil is warm. This heat-related performance drop often persists even after replacing the main pump. The issue is frequently traced to the spool valves in the hydraulic valve body controlling the 'depth set' function or clogged inlet screens in the pilot control fittings. Re-torquing the spool valves or cleaning the pilot screens typically resolves the sluggishness. Have your dealer verify the pilot system pressure and valve body integrity before major component replacement.
What engine is used in the PC50UU-2 (S/N 8001-UP) and what are its known quirks?
The PC50UU-2 (S/N 8001-UP) uses the Komatsu 4D84 diesel engine. Known quirks include fuel starvation and injector pump wear causing rough running and stalling after approximately 10 minutes of operation. Starting can be difficult if the machine has been sitting; priming the fuel system with 5-6 pumps of the hand primer often eliminates excessive cranking times. Have your dealer verify the fuel injection pump timing and injector spray patterns.
What undercarriage and wear patterns are typical for this machine type?
The PC50UU-2 utilizes a 400 mm wide rubber track system. Common wear patterns include 'walking fatigue' affecting travel speed and abnormal low oil circuit pressure in the hydraulic cylinders. The machine is a zero-tail swing design with a 1,750 mm upper body and a 2,000 mm overall width. Track tension and roller alignment should be checked regularly, as improper tension accelerates rubber wear and affects the final drive lifespan.
What are the common electrical or sensor issues for the PC50UU-2?
The control monitor panel is a frequent point of failure, often causing loss of fuel gauge, hour meter, lights, and high-speed functions. Intermittent operation is usually caused by wiring issues or poor ground connections rather than a failed panel. Komatsu excavators use 'biscuit' mounts for the cab, requiring a specific ground wire connecting the cab to the machine frame. Corrosion or loose connections at this ground point cause quirky electrical behavior. Have your dealer verify the cab-to-frame ground continuity and monitor panel input signals.
What specific items must be checked when buying a used PC50UU-2 (S/N 8001-UP)?
Verify the serial number range (8001-UP) to confirm the correct engine and hydraulic configuration. Check for gray market status; non-US models may have Japanese/English gauges and lack proper support. Test the offset boom function, as it can crowd in tight spaces and rotate the machine unexpectedly. Inspect the hydraulic thumb operation, which may be slow unless bucket curl is engaged simultaneously. Check the control pattern shifter (SAE vs. Japanese) and ensure it switches cleanly. Verify the condition of the rubber tracks and sprockets, as replacement costs are high. Have your dealer verify the engine compression and hydraulic pump flow rates.
What fluids are specified for the PC50UU-2 hydraulic and final drive systems?
The hydraulic system and track motors share the same circuit and typically use Komatsu hydraulic oil or equivalent universal tractor transmission fluid (UTTF) meeting Komatsu specifications. The final drives are specified to use SAE 30 engine oil in some service references, though heavier gear oils are sometimes used by operators in warmer climates. The hydraulic system capacity is approximately 55 liters. Use Komatsu EO or TO hydraulic fluid for optimal seal compatibility. Have your dealer verify the current fluid specifications against the machine's specific serial number and operating environment.
