Servicing the PC50UU-2E(S/N 10835-UP (FOR EC)) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor hydraulic oil viscosity and particle count to prevent pump wear. Check coolant SCA levels every 500 hours to avoid liner cavitation in the 4D88E engine. Inspect final drive oil for metal shavings indicating gear wear. Use Komatsu Genuine Lubricants to maintain seal integrity. Track fuel filter restriction to prevent injector issues. Analyze swing bearing grease for contamination.
Corrective & Common Repairs
Replace hydraulic hose assemblies showing abrasion or bulging. Repair or replace boom cylinder seals to address external leaks. Fix track tensioner leaks by replacing the seal kit. Replace worn track shoes and pads to maintain ground pressure. Address hydraulic pump noise by checking suction lines for air ingress. Replace the fuel water separator element to protect injectors.
Overhaul & Rebuild Points
Rebuild the hydraulic pump when flow drops below specification or internal leakage increases. Overhaul the final drives if oil contamination exceeds limits or noise indicates bearing failure. Replace swing bearing rollers and raceway when pitting or excessive play occurs. Rebuild the engine if compression drops below 25 kg/cm² or oil consumption exceeds 1 liter per 10 hours. Inspect the boom stick structure for crack propagation at weld joints.
Seasonal & Environment Servicing
Switch to low-viscosity hydraulic oil in cold climates to ensure proper flow. Use antifreeze coolant with correct concentration to prevent freezing. Check the battery charging system for cold-weather performance. Inspect the air intake heater operation for reliable starts. Clean the radiator and oil cooler fins frequently to prevent overheating in dusty environments. Grease pivot points more often in wet or muddy conditions.

PC50UU-2E(S/N 10835-UP (FOR EC)) serial number reference
Locate the factory PIN/serial plate 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. For export ('FOR EC') variants, the 17-character ISO PIN begins with 'KMT'. Positions 4–8 encode the model family and configuration. Position 9 is a check digit, position 10 is the year letter, position 11 is the plant code, and positions 12–17 are the serial sequence. Cross-reference the riveted plate against the chassis-stamped serial number on the right-hand side frame casting; a mismatch indicates potential tampering or stolen equipment.

Frequently asked questions
What engine does the PC50UU-2E use?
The PC50UU-2E uses the Komatsu 4D88E diesel engine, delivering approximately 40 horsepower (29.4 kW) at 2,400 rpm.
What is the operating weight of the PC50UU-2E?
The operating weight varies by configuration, ranging from 5,100 kg to 5,300 kg (11,243 to 11,687 lbs).
What model replaced the PC50UU-2E?
The PC50UU-2E was succeeded by the PC50MR-2 series, which updated the design for modern emissions standards and operational requirements.
What PC50UU-2E(S/N 10835-UP (FOR EC)) owners discuss
What engine powers the PC50UU-2E (S/N 10835-UP) and what are its output ratings?
The PC50UU-2E uses a Komatsu 4D84 diesel engine. Output is rated at 39 HP (29 kW) at 2,350 RPM. Some sources cite a 4D88E-5 engine with 41 HP gross/39 HP net for the broader PC50 series, but the 4D84 is the specific unit for the UU-2 generation. Torque is 139 Nm (103 ft-lb) at 1,440 RPM. Variations exist by configuration/series depending on the exact sub-model year and regional emissions package. Have your dealer verify the exact engine plate for this serial range.
What are the common hydraulic behaviors and failure modes for this machine?
Operators report 'walking fatigue' where travel speed drops due to low oil circuit pressure. This is often caused by a malfunctioning canceling solenoid valve or a two-level overflow solenoid valve. Slow slewing speed is another common issue, often linked to a worn gear pump or leaks in the swing hydraulic lines. The planetary drive motors in the travel system wear over time, and debris in the planetary oil can cause low tracking power. Check the booster pump slip shaft for sticking.
What undercarriage and wear patterns are typical for the PC50UU-2E?
The machine has a 400 mm track width. Final drives are a known wear point; one side may feel weak before failing completely. The travel motors are prone to internal debris accumulation. The offset boom (UU) configuration places specific stress on the swing mechanism. Rubber tracks on later units or replacements show wear patterns consistent with high ground pressure in tight urban jobs. Check the final drive shafts and travel motor seals for leaks.
What electrical or sensor issues are frequently reported?
The control monitor panel is a common failure point, causing loss of fuel gauge, hour meter, lights, and high-speed functions. Intermittent operation often points to wiring issues between the panel and the machine. Ground connections are critical; the cab is mounted on insulating biscuits and must be grounded to the machine frame with a wire. Faulty ground connections can cause multiple warning signals and random shutdowns.
What is the standard fluid specification for the hydraulic system and final drives?
The hydraulic system uses Komatsu Hydraulic Oil (HO) or equivalent ISO 46 grade. The final drives are specified for SAE 30 engine oil in some service references, though heavier gear oils are sometimes used by operators in cold climates. The engine oil capacity is approximately 2 gallons (7.5 liters). The hydraulic system fluid capacity is approximately 55 liters (14.5 gallons). Have your dealer verify the exact fluid specs for your operating temperature range.
What are the key dimensions and weight specs for the PC50UU-2E?
Operating weight is approximately 10,450 lbs (4,740 kg) to 11,687 lbs (5,300 kg) depending on configuration. Transport length is 18.2 ft (5,550 mm). Transport width is 6.6 ft (2,000 mm). Transport height is 8.6 ft (2,625 mm). Max digging depth is 12.5 ft (3.8 m). Max digging height is 19.5 ft (5.95 m). Tail swing radius is 3.3 ft (990 mm). Values vary by configuration/series based on counterweight and attachment package.
What should be checked when buying a used PC50UU-2E (S/N 10835-UP)?
Verify the machine is not a gray market import by checking the gauge console for English-only operation and confirming the serial number with a dealer. Test the offset boom function; it should not interfere with the cab orrops. Check the control pattern shifter (SAE vs. Japanese) for smooth operation. Inspect the final drives for weakness or leaks. Verify the cab ground wire is intact. Check for water in the hydraulic oil reservoir. Have your dealer verify the serial number matches the PC50UU-2E specification sheet.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
