Komatsu PW75R-2(S/N 22E0200001-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PW75R-2 is a wheeled midi-excavator designed primarily for European utility and municipal markets. It is powered by a 4D98E-1FB inline-four diesel engine producing 68 hp (51 kW) net power. The machine features a hydrostatic transmission with two forward and two reverse gears, allowing a maximum travel speed of 18.7 mph (30.1 km/h). Operating weight ranges from 7,700 kg to 9,000 kg (16,975 lbs to 19,842 lbs) depending on the configuration and counterweight. Production years span approximately 2000 to 2006. It succeeded the PW75-1 and was eventually replaced by the PW95R-2 in Komatsu's wheeled lineup. Configurations offered include varying bucket capacities from 0.086 m³ to 0.46 m³ and selectable hydraulic power modes (Power and Economy).
Across the PW75R-2's generation, Komatsu emphasized compact tail swing (152.4 cm) and high lifting capacity relative to its weight class. The machine matters in the used and parts market because its 4D98E-1FB engine is a robust, simple-to-service unit common across multiple Komatsu mini and midi excavators. The PW75R-2's wheeled undercarriage and hydrostatic drive offer lower ground pressure than crawlers, making it valuable for paved surfaces and indoor work. Parts availability remains strong due to the shared platform with the PC75R-2 and PW95R-2, ensuring that components like the variable displacement axial piston pump and swing motor are widely supported.

Servicing the PW75R-2(S/N 22E0200001-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Use KOWA oil analysis at every 500-hour interval to monitor engine wear metals and hydraulic system contamination. Check the coolant SCA concentration at 500 hours to prevent liner cavitation in the 4D98E-1FB engine. Monitor hydraulic oil viscosity and particle count to detect pump wear early. Inspect the fuel water separator daily to protect the injection system. Track tire pressure weekly to ensure even wear on the 7.50-20 tires and maintain stability during lifting operations.
Corrective & Common Repairs
Address hydraulic hose leaks promptly, as the PW75R-2 uses ORFS couplings that can degrade if exposed to heat or abrasion. Replace the hydraulic return filter if pressure differential indicators show clogging. Inspect the swing bearing for play or unusual noise, which indicates worn rollers. Check the hydrostatic transmission pump for loss of travel speed or power. Replace worn track rollers or idlers on the wheeled chassis to prevent uneven tire wear and vibration. Repair any electrical wiring chafing near the cab hinge.
Overhaul & Rebuild Points
Plan for a hydraulic pump overhaul when flow rates drop below specification or internal leakage causes slow cycle times. Rebuild the swing motor if backlash exceeds limits or hydraulic pressure cannot be maintained. Inspect the 4D98E-1FB engine for excessive oil consumption or blue smoke, indicating piston ring or valve guide wear. Check the final drive gears for pitting or noise, which signals bearing failure. Replace the turbocharger if shaft play is detected or oil leaks past the seals. Overhaul the hydraulic cylinders if rod scoring or seal leakage is present.
Seasonal & Environment Servicing
In cold weather, check the coolant freeze protection level and use the correct glycol concentration. Drain the fuel water separator more frequently to prevent ice formation. In hot weather, clean the radiator and oil cooler cores daily to prevent overheating. Inspect the hydraulic oil cooler for blockage. Use the correct viscosity engine oil for the ambient temperature range. Check the air intake heater operation if equipped. Inspect the cab heater and defroster for proper function. Protect the hydraulic hoses from UV degradation and extreme heat.

Frequently asked questions
What engine does the PW75R-2(S/N 22E0200001-Up) use?
The PW75R-2(S/N 22E0200001-Up) uses the Komatsu 4D98E-1FB inline-four diesel engine.
What is the operating weight of the PW75R-2?
The operating weight varies by configuration, ranging from 7,700 kg to 9,000 kg (16,975 lbs to 19,842 lbs).
What model replaced the PW75R-2?
The PW95R-2 succeeded the PW75R-2 in Komatsu's wheeled midi-excavator lineup.
What PW75R-2(S/N 22E0200001-Up) owners discuss
What engine model powers the PW75R-2 (S/N 22E0200001-Up) and what are its key performance ratings?
The machine uses a 4-cylinder Komatsu 4D98E-1FB diesel engine. Net power is rated at 68 hp (51 kW) at 2,300 rpm. Net torque is 173 lb-ft (235 Nm) at 1,500 rpm. Displacement is 202.5 cu in (3,318 cc). This engine is a compact diesel unit designed for the midi-excavator class, providing high torque at low RPMs for hydraulic pump drive efficiency. Variations in torque curves may exist depending on the specific regional emissions package installed at the factory. Verify the exact engine plate data on the machine, as serial breaks can indicate minor component updates within the same model family.
How does the hydrostatic transmission behave, and what are common hydraulic system pressures?
The PW75R-2 utilizes a hydrostatic transmission with four driving wheels. Travel speed is approximately 18.7 mph (30 km/h). The hydraulic system uses a variable displacement axial piston pump with a flow capacity of 44.2 gpm (167 lpm). The system relief valve pressure is set to 3,843.6 psi (265 bar). Owners note that the hydrostatic drive provides smooth, stepless speed control but requires careful monitoring of hydraulic fluid temperature during continuous high-load operation. The system offers selectable 'Power' and 'Economy' modes to balance digging force against fuel consumption. If the machine loses power on inclines, check the travel shock valves and pump pressure settings.
What are the typical undercarriage and wear patterns for this wheeled midi-excavator?
As a wheeled machine, the PW75R-2 relies on pneumatic tires (size 7.50-20) rather than tracks, eliminating undercarriage wear but introducing tire-specific maintenance. Operators report that rubber tracks on similar compact excavators (like the PC75UU-2) are prone to slipping on slopes and rapid wear in rocky terrain, whereas the PW75R-2's tire setup requires monitoring for punctures and uneven wear from frequent repositioning. The slew ring and swing motor are critical wear points; listen for grinding or clunking during rotation, which indicates worn bearings or motor gears. Boom and bucket pin play should be checked regularly, as excessive slop reduces digging efficiency and accelerates structural stress. The articulated boom option, if equipped, adds weight above the cab and is prone to stress cracks; straight booms are generally preferred for heavy-duty work.
What are common electrical or sensor issues reported for this series?
Komatsu excavators of this era rely on electronic control systems that can be sensitive to power supply stability. Owners report intermittent starting, dashboard failures, or random shutdowns often linked to faulty sensors or unstable voltage. Wiring harnesses in older units may become brittle or disconnected, particularly around the cab and engine compartment. Check for loose connectors, corroded grounds, and damaged wire insulation. A single faulty sensor can trigger multiple warning signals. Ensure the alternator (60 amps) and battery connections are clean and tight to prevent erratic electronic behavior. If the machine exhibits erratic hydraulic response or warning lights, inspect the main wiring harness for chafing or disconnection.
What fluids and capacities are specified for the PW75R-2 (S/N 22E0200001-Up)?
Engine oil capacity is 9.4 liters (2.5 gallons). Hydraulic tank capacity is 158 liters (41.7 gallons). Front axle differential oil capacity is 4.8 liters (1.3 gallons). Komatsu specifies API CD grade oil for the engine and UTTO fluid for the front axle differential. The hydraulic system requires Komatsu HYDO or equivalent high-quality hydraulic oil. Coolant capacity is not explicitly stated in the provided specs for this exact serial range, but standard Komatsu super-coolant AF-NAC is recommended. Always verify fluid types and levels against the machine's specific operation and maintenance manual, as regional specifications may vary.
What are the key dimensions and operating weight for this machine?
Operating weight ranges from 7,700 to 9,000 kg (16,975 to 19,842 lb) depending on configuration. Overall width is 2.26 m (7 ft 5 in). Height to top of cab is 2.96 m (9 ft 8 in). Tail swing radius is 1.50 m (4 ft 11 in). Ground clearance is 0.34 m (1 ft 1 in). Maximum digging depth is approximately 4.27 m (14 ft). Bucket capacity ranges from 0.086 to 0.265 m³ (0.11 to 0.35 cu yd). These dimensions make the machine suitable for confined spaces and utility work. Verify exact weight and dimensions with the serial-specific spec sheet, as counterweight and attachment options affect these figures.
What should be checked when buying a used PW75R-2 (S/N 22E0200001-Up)?
Inspect the hydraulic pump for brass particles in the oil, which indicate wear in the pump, swing motor, or travel motors. Check the fuel lines for brittleness and leaks, as original lines can degrade over time. Verify the condition of the slew ring and swing motor for noise or play. Test all hydraulic functions for smooth operation and check for cylinder leaks. Inspect the engine for hard starting, excessive smoke, or oil leaks. Check the wiring harness for disconnections or damage. Ensure the hydrostatic transmission shifts smoothly and holds pressure on inclines. Have your dealer verify the engine serial number and hydraulic pump model against the machine's documentation to confirm compatibility and service history.
