Komatsu PW75R-2(S/N 22E0200243-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PW75R-2 is a wheeled midi excavator designed for European markets, produced between 2000 and 2006. It succeeds the PW75-1 and is part of the PW75R-2 series, which includes variants like the PW95R-2. The machine features a Komatsu 4D98E-1FB engine delivering 68 hp (51 kW) net power. Operating weight ranges from 7,700 to 9,000 kg (16,975 to 19,842 lb) depending on configuration. It offers a reference bucket capacity of 0.4 cu yds (0.3 m³) and utilizes a hydrostatic transmission with two forward and two reverse gears.
Across the PW75R-2 generation, Komatsu introduced fully opening bonnets to group service points for ground-level access and fitted all hydraulic hoses with ORFS couplings for better sealing and easier replacement. The machine matters in the used market because its compact 216.4 cm (85.2 in) width and 152.4 cm (60.0 in) tail swing radius allow operation in tight urban and utility sites. Its reliability and the availability of the 4D98E-1FB engine make it a staple for municipal and landscaping contractors.

Servicing the PW75R-2(S/N 22E0200243-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA oil analysis at every 500-hour interval to monitor engine wear metals and hydraulic fluid contamination. Check the coolant SCA concentration at 500 hours to prevent scaling and corrosion in the 4D98E-1FB engine. Monitor the hydraulic system relief valve pressure, rated at 3844 psi (265 Bar), to detect pump wear early. Track fuel consumption trends via KOMTRAX telematics to identify inefficient power modes. Inspect the air filter restriction indicator daily to protect the turbocharger from dust ingress.
Corrective & Common Repairs
Address hydraulic hose leaks promptly; the PW75R-2 uses ORFS couplings that require specific sealing rings. Replace the hydraulic return filter at 500 hours to protect the variable displacement axial piston pump. Check the swing bearing for play and inspect the swing machinery oil level at 1000 hours. Monitor the hydrostatic transmission for smooth gear shifts between the two forward and two reverse gears. Inspect the 7.50-20 tires for uneven wear caused by the 207.3 cm (81.6 in) wheelbase.
Overhaul & Rebuild Points
Plan for major component overhaul around 10,000 to 15,000 hours. Inspect the 4D98E-1FB engine valves and injectors during the 2000-hour comprehensive evaluation. Check the final drive oil for metal particles at 1000 hours to assess gear wear. Inspect the swing circle and undercarriage rollers for wear at 4000 hours. Evaluate the hydraulic pump flow capacity, rated at 44.2 GPM (167 LPM), for efficiency loss. Replace all seals and O-rings during any major hydraulic system disassembly.
Seasonal & Environment Servicing
In cold climates, check the coolant glycol content and SCA levels before winter to prevent freezing. Drain the fuel separator daily to remove water that can cause injector issues in the 4D98E-1FB engine. In dusty environments, clean the radiator and oil cooler fins daily to maintain the 51 kW (68 hp) output. Inspect the 7.50-20 tires for cuts and abrasions on rocky terrain. Grease all pivot points frequently to prevent corrosion and wear in wet or muddy conditions.

| CA115 | Engine crankshaft speed sensor and backup speed sensor failure. | Broken sensor, wiring issue, or connector corrosion. | Replace the speed sensor and verify voltage at the pin connector. |
| CA441 | Battery voltage too low. | Weak battery, failing alternator, or loose connections. | Check battery health and alternator output; replace if necessary. |
| CA451 | Common rail pressure sensor feedback value too high. | Malfunctioning rail pressure sensor or actual overpressure condition. | Diagnose the fuel rail pressure sensor and check pump lines for blockages. |
| AA10NX | Air cleaner clogging. | Dirty or blocked air filter element. | Replace the air filter element. |
| DGH2KB | Hydraulic oil temperature sensor short circuit. | Faulty temperature sensor or shorted wiring harness. | Replace the hydraulic oil temperature sensor. |
| DW43KB | Travel speed solenoid valve short circuit. | Electrical short in the travel speed control solenoid or harness. | Replace the solenoid valve and inspect the wiring harness for chafing. |
| B@BCNS | Engine coolant overheating. | Low coolant level, clogged radiator fins, or fan belt failure. | Check radiator fins, fan belt, and coolant level; clean or replace as needed. |
| CA122 | Intake air pressure sensor feedback voltage too high. | Faulty intake pressure sensor or restricted airflow. | Verify the intake pressure sensor operation and inspect wiring. |
| CA111 | Internal engine controller fault. | ECM internal hardware failure. | Replace or reprogram the ECM. |

Frequently asked questions
What engine does the PW75R-2(S/N 22E0200243-Up) use?
The PW75R-2(S/N 22E0200243-Up) uses the Komatsu 4D98E-1FB engine, a 4-cylinder, 3318.4 cc (203 cu in) diesel unit producing 68 hp (51 kW) net power at 2300 RPM.
What is the operating weight of the PW75R-2?
The operating weight varies by configuration, ranging from 7,700 to 9,000 kg (16,975 to 19,842 lb). A common specification for this model is 8,500 kg (18,739 lb).
What model replaced the PW75R-2?
The PW75R-2 was succeeded by the PW95R-2 in Komatsu's wheeled midi excavator lineup. The PW75R-2 itself succeeded the PW75-1 model.
What PW75R-2(S/N 22E0200243-Up) owners discuss
What engine model powers the PW75R-2(S/N 22E0200243-Up) and what are its key performance specifications?
The machine uses a 4-cylinder Komatsu 4D98E-1FB diesel engine. Net power is 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 cu cm). The engine oil capacity is 9.4 liters. The engine relies on API CD specification oil for operation.
How does the hydraulic system behave, and what are the common failure points for this series?
The system uses a variable displacement axial piston pump delivering 44 gpm (167 lpm) at a relief pressure of 3,843.6 psi. Owners report that slow movements or jerky operation often indicate worn pump seals or contaminated fluid. Brass debris in the hydraulic oil typically originates from the pump, swing motor, or travel motors. The hydraulic tank capacity is 158 liters. Fluids must meet API CD specifications.
What are the typical undercarriage and wear patterns for the PW75R-2?
The machine operates on a hydrostatic transmission with four driving wheels and 7.50-20 tires. Undercarriage wear is a primary cost factor; rubber tracks are prone to slipping on slopes and rapid wear, while steel tracks with rubber inserts are preferred for heavy work. Inspect rollers, sprockets, and idlers for uneven wear. Boom, stick, and bucket pins require frequent checking for play, as excessive slop indicates bushing wear.
What electrical or sensor issues are commonly reported by operators?
The PW75R-2 relies on electronic control systems where a single faulty sensor or unstable power supply can trigger multiple warning signals. Common issues include intermittent starting, dashboard failures, and random shutdowns. Wiring harnesses may become disconnected or damaged, particularly in older units. The system operates on 12 V with a 60-amp alternator.
What specific items must be checked when buying a used PW75R-2(S/N 22E0200243-Up)?
Verify the serial number matches the 22E0200243-Up range to ensure correct service manual application. Inspect the engine for hard starting, excessive smoke, or knocking. Test all hydraulic functions for smooth operation and check for oil leaks. Examine the undercarriage for track tension and roller wear. Check the boom and bucket pins for play. Inspect the swing motor for grinding or clunking noises. Verify the condition of the fuel lines, as original lines may be brittle. Check the cab structure for stress cracks, especially around the articulated boom base if equipped.
What are the operating weight and dimension constraints for this machine?
Operating weight is 18,739 lbs (8,500 kg). Overall width is 7.08 in (18 cm) with a tail swing radius of 4.93 ft (1.5 m). Height to the top of the cab is 9.72 ft (3 m). Ground clearance is 1.12 ft (0.34 m). The reference bucket capacity ranges from 0.2 to 0.4 cu yd (0.15 to 0.265 m³). These values vary by configuration and series.
What safety-critical maintenance is required for the swing mechanism and structural integrity?
Inspect the slew bearing and swing motor for wear. Listen for grinding or clunking during rotation. Check structural welds around the boom base and swing area for cracks. If the machine has an articulated boom, verify the guarding and structural integrity, as these add weight above the cab and increase stress. Have your dealer verify swing motor pressure and slew bearing clearance.
