Komatsu WB140PS-2(S/N 140F50098-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WB140PS-2 is a mid-size power-shift backhoe loader in the WB140 series, designed for utility, municipal, and general construction work. It is equipped with the Komatsu S4D106-2XFH diesel engine, delivering approximately 86 hp. The machine features a closed-center load-sensing hydraulic system and an electronically controlled four-wheel-drive full powershift transmission. Operating weight varies by configuration, typically ranging between 6,350 to 6,800 kg (14,000 to 15,000 lb). Production years for the WB140PS-2 span the late 1990s through the early 2000s. It succeeded the WB140PS and was eventually replaced by the WB140-3 series. Configurations offered include standard and extended backhoe booms, various bucket widths, and optional EGMTM (Electronic Gear Management) controls.
Across the WB140 series generations, Komatsu transitioned from mechanical to electronic controls, notably introducing the PS (Power Shift) variant with twist-grip or EGMTM gear management for seamless direction changes under load. The WB140PS-2 is significant in the used and parts market because its S4D106 engine is robust and widely supported, and its modular hydraulic architecture allows for cost-effective rebuild. The machine remains popular for its 4WD capability and compact turning radius, making it a staple in tight urban jobsites. Parts availability is high due to the large fleet size, and the PS-2 generation serves as a critical bridge between older mechanical systems and modern electronic diagnostics.

Servicing the WB140PS-2(S/N 140F50098-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor Komatsu KOWA oil analysis for the S4D106-2XFH engine to detect early wear in piston rings and cylinder liners. Check hydraulic oil for water contamination in the front and rear axles, which are prone to seal failure in wet conditions. Analyze transmission fluid for clutch material wear to predict powershift clutch pack failure. Inspect the fuel filter element for water accumulation in the separator to protect the high-pressure injection system. Track coolant pH levels to prevent corrosion in the aluminum heat exchanger cores.
Corrective & Common Repairs
Address frequent failures in the EGMTM solenoid valves, which cause erratic gear shifting and loss of power shift function. Replace worn steering cylinder seals to correct drift and loss of steering assist. Repair cracked exhaust manifolds common on the S4D106 engine due to thermal cycling. Replace the hydraulic pilot filter element when pressure drop exceeds limits to restore control valve responsiveness. Fix leaking front axle hydraulic oil seals, a common issue that contaminates the brake system.
Overhaul & Rebuild Points
Rebuild the powershift transmission when clutch pack wear exceeds specifications, indicated by slipping in forward or reverse gears. Overhaul the S4D106-2XFH engine when compression drops below 25 bar or oil consumption exceeds 1 liter per 10 hours. Recondition the hydraulic pump when flow output falls below 90% of rated capacity, causing slow loader cycle times. Replace the final drive planetary gears when backlash exceeds 0.5 mm, leading to noise and vibration. Inspect the turbocharger shaft play for excessive axial movement.
Seasonal & Environment Servicing
In cold climates, use Komatsu Super-coolant AF-NAC rated for -35°C to prevent engine block cracking. Drain and replace hydraulic oil in axles with lower viscosity grades to ensure proper steering response in freezing temperatures. Inspect rubber hoses and seals for hardening due to UV exposure in summer operations. Clean radiator and hydraulic oil cooler fins regularly to prevent overheating in dusty environments. Check the air cleaner restriction indicator frequently in high-dust conditions to prevent engine wear.

Frequently asked questions
What engine does the WB140PS-2 (S/N 140F50098-Up) use?
The Komatsu WB140PS-2 (S/N 140F50098-Up) uses the Komatsu S4D106-2XFH diesel engine.
What is the operating weight of the WB140PS-2?
The operating weight varies by configuration, typically ranging between 6,350 to 6,800 kg (14,000 to 15,000 lb).
What model replaced the WB140PS-2?
The WB140PS-2 was replaced by the WB140-3 series backhoe loader.
What WB140PS-2(S/N 140F50098-Up) owners discuss
What engine does the WB140PS-2 (S/N 140F50098-Up) use, and are there known thermal issues?
The WB140PS-2 (S/N 140F50098-Up) uses the Komatsu S4D106-2XFH engine. Operators report that after running for five or more hours, the machine may shut down and fail to restart for 30 minutes due to excessive heat buildup. This is often caused by restricted radiators, incorrect coolant types, or faulty thermostats preventing the engine from reaching optimal thermal equilibrium (approx. 190°F). Use of cheap coolant can lead to internal contamination and head gasket failure. Have your dealer verify cooling system integrity and thermostat operation before purchase or operation.
What are the common transmission and hydraulic pressure behaviors for this series?
The WB140PS-2 features a closed-center load-sensing hydraulic system and a full powershift transmission. Community reports indicate that transmission torque converter pressure should read approximately 40 PSI at idle and 130 PSI at full throttle. If the low-pressure side reads higher than the specified 8 to 10 PSI, it indicates a system fault. The hydraulic system is sensitive to fluid contamination; the bottom suction filter in the hydraulic tank is prone to loading with debris, which can impair pump function and system responsiveness.
What electrical or sensor issues are typical for this machine?
A frequent electrical fault involves the starter safety relay, which is often misidentified in schematics as a preheat relay. The machine may have normal dashboard lights and hear the lift pump ticking but will not crank. Jumping the starter solenoid directly often confirms the relay is the failure point. Additionally, the transmission control board uses common Panasonic relays that are soldered in; these are known failure points and are often replaced in bulk by owners to prevent intermittent transmission control issues.
What undercarriage or wear patterns are typical for this machine type?
As a backhoe loader, the WB140PS-2 experiences high stress on the front axle and steering joints due to the articulated frame design. The hydraulic cylinder seal kits for the boom, arm, and bucket are common wear items. The machine utilizes a closed-center load-sensing system, which requires strict adherence to fluid cleanliness to prevent wear on the high-pressure pumps and steering units. Regular inspection of the hydraulic suction filter is critical to prevent premature component wear.
What engine quirks are associated with the S4D106 series in this application?
The S4D106-2XFH engine in this serial range is sensitive to cooling system maintenance. Operators note that using non-standard or cheap coolant can lead to rapid degradation of the cooling system's internal components. The engine relies on precise thermal management; failure to maintain the correct coolant type and level can result in mild seizure of components due to expanded tolerances at high temperatures. Always use the specified Komatsu Super-coolant AF-NAC or equivalent high-quality diesel engine coolant.
What are the common hydraulic fluid and filter maintenance requirements?
The hydraulic system requires Komatsu EO or equivalent high-quality hydraulic oil. The suction filter located at the bottom of the hydraulic tank is a critical maintenance point; it loads quickly with debris and must be cleaned or replaced regularly to prevent pump cavitation. The cooling system also requires specific coolant to prevent corrosion and overheating. Fluid specifications vary by configuration and series; consult the operation and maintenance manual for exact capacity and grade.
What to check when buying a used WB140PS-2 (S/N 140F50098-Up)?
Verify the serial number plate location on the right-hand side of the frame below the cab or left-hand side of the engine compartment. Check starter safety relay functionality by attempting to crank after a short run; if it fails to crank but jumps to life, the relay is likely faulty. Inspect the radiator core for restrictions and check for coolant loss. Test transmission torque converter pressure at idle and full throttle to ensure it falls within the 40 PSI and 130 PSI ranges respectively. Check the hydraulic suction filter for excessive debris. Have your dealer verify engine thermal equilibrium and cooling system integrity.
