Servicing the PW95R-2(S/N 21D0200001-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize Komatsu KOWA fluid analysis at every 500-hour interval to monitor engine wear metals, hydraulic particle counts, and coolant SCA concentration. The PW95R-2's 4D106-1FB engine requires strict adherence to sulfur content guidelines; if diesel sulfur exceeds 0.5%, halve the engine oil change interval. Monitor hydraulic pump flow capacity (180 L/min) and relief valve pressure (275 bar) trends to detect axial piston pump wear early. Check front axle differential and final reduction gear oil levels for UTTO fluid contamination.
Corrective & Common Repairs
Address hydraulic hose leaks by replacing ORFS couplings, which are standard on the PW95R-2 for easier sealing. Inspect the hydrostatic transmission drive motors and axles for oil leaks, as the system uses oil-immersed multiple disc brakes on all four wheels. Check the swing bearing and swing drive oil for contamination, which can cause the 9 RPM swing speed to degrade. Replace the hydraulic return filter at 500 hours to protect the variable displacement axial piston pump from debris-induced failure.
Overhaul & Rebuild Points
Plan major overhauls for the 4D106-1FB engine around 10,000 hours, focusing on injector calibration and turbocharger inspection. The hydrostatic transmission requires comprehensive evaluation at 2,000-hour intervals, including pump swashplate wear checks. Inspect the front axle oscillation and final reduction gears for gear tooth wear. Structural integrity checks of the boom and stick welds are critical at 1,000-hour intervals to prevent fatigue failures in the monoboom or two-piece boom configurations.
Seasonal & Environment Servicing
In cold climates, verify engine pre-heating function and check DEF levels for Tier 4 compliance. Ensure the coolant SCA test confirms proper glycol content and pH to prevent freezing. In dusty environments, clean the air filter outer element frequently and monitor the restriction indicator. For high-sulfur fuel regions, reduce engine oil change intervals to 1/4 of the standard schedule. Inspect the radiator and oil cooler fins for debris buildup to maintain cooling efficiency during heavy duty cycles.

What is the operating weight of the PW95R-2?
The operating weight is 10,100 kg (22,267 lbs), varying by configuration such as counterweight, boom type, and tire setup.
What model replaced the PW95R-2?
The PW95R-2 was succeeded by the PW98MR-6 and later the PW98MR-10 in Komatsu's wheeled midi excavator lineup.
What PW95R-2(S/N 21D0200001-Up) owners discuss
What engine model and net power rating are specified for the PW95R-2 (S/N 21D0200001-Up)?
The machine uses a 4D106-1FB engine. Net power is 83 hp (62 kW) at 2200 rpm. Net torque is 229 lb-ft (310 Nm) at 1500 rpm. Displacement is 269 cu in (4,413 cu cm). The engine has 4 cylinders. Power is measured per SAE J1349. Operating weight ranges from 8,800 kg to 10,100 kg (19,400 lb to 22,267 lb) depending on configuration. Variations in weight and power exist by configuration/series.
What are the typical hydraulic system pressures and flow rates for this model?
Hydraulic pump flow capacity is 48 gpm (180 lpm). The pump type is variable displacement axial piston. Hydraulic system relief valve pressure is 3,988.6 psi. The hydraulic circuit oil capacity is 170 L (45 gal). The crankcase sump oil capacity is 12.5 L (3.3 gal). Front axle differential oil capacity is 9.0 L (2.4 gal). Final reduction gear oil capacity varies by side. Fluid specifications include API CD oil for the hydraulic circuit and crankcase, and UTTO fluid for the front axle differential.
What are common undercarriage and wear patterns for this wheel-mounted excavator?
The machine uses 8.25-20 tires. Travel speed is 19 mph (31 kph). The transmission is hydrostatic with 2 forward and 2 reverse gears. Swing speed is 9 rpm. Tail swing radius is 5.14 ft (1.57 m). Overall width is 7.6 in (19 cm) narrower than standard tracks, allowing tight access. Ground clearance is 1.33 ft (0.4 m). Height to top of cab is 9.91 ft (3.02 m). Upper structure clearance is 3.61 ft (1.1 m). Wheelbase is 7.22 ft (2.2 m). Operators note that tire wear and axle seal integrity are critical maintenance points due to the high-speed travel capability.
What engine cooling issues are reported by operators?
Operators report high engine temperature issues, particularly when using cylinders or traveling. The cooling package includes a radiator, hydraulic oil cooler, and charge-air cooler. Debris packed between heat exchangers can cause overheating. If temperature rises during heavy work but falls at idle, cooling capacity may be marginal. Coolant level checks when cold are essential. Engine gasket and radiator cap failures have been documented in service discussions.
What electrical and sensor issues are common in Komatsu excavators of this era?
Komatsu excavators rely on electronic control systems. Faulty sensors or unstable power supplies can trigger multiple warning signals. Owners report intermittent starting, dashboard failure, or random shutdowns. The operating voltage is 12 V. The alternator supplies 80 amps. Battery state of charge, terminals, and main starter cables should be checked if the engine will not start. Voltage collapse during starting indicates battery or ground issues.
What hydraulic behaviors are typical for this machine type?
The hydraulic system uses a main pump and gear pump. Swing motor weight is 87 kg. Main pump and gear pump assembly weight is 97 kg. The swing circle weight is 124 kg. Hydraulic noise or cavitation indicates oil level or suction side issues. If all hydraulic functions are slow, check oil level, filters, engine RPM, and oil temperature. If one function is slow, check the specific cylinder, valve, or hose. Hydraulics may work cold but become weak when hot due to internal leakage or viscosity changes.
What should be checked when buying a used PW95R-2 (S/N 21D0200001-Up)?
Verify the exact serial number prefix to confirm the correct service manual and specifications. Check the hydraulic pump pressure and flow rate against manufacturer specifications. Inspect the engine cooling system for debris and leaks. Test the travel motors and final drives for noise and speed consistency. Check the swing brake for holding position. Inspect the tires for wear and axle seals for leaks. Verify the condition of the hydraulic filters and oil quality. Check for multiple fault codes indicating electrical issues. Have your dealer verify the engine and hydraulic system performance.
