Komatsu WB140-2(S/N 140F11451-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WB140-2 is a backhoe loader manufactured from 1999 to 2006. It is powered by a Komatsu S4D106-2XFH turbocharged diesel engine with 93 gross horsepower. The operating weight ranges from 16,600 to 19,731 pounds depending on configuration. The WB140-2 succeeded the WB140 series and was followed by the WB140-3. Configurations included standard and extended backhoe options, with operating weights varying by attachment package.
The WB140-2 introduced increased hydraulic speeds and Tier-2-compliant engines compared to its predecessor. It features a Load Independent Flow Divider valve block for improved control. The machine remains relevant in the used market due to its robust S4D106 engine and durable chassis. Parts availability is supported by the extensive WB140-2 parts catalog, with specific service manuals covering serial ranges starting from 140F10001 and 140F11451.

Servicing the WB140-2(S/N 140F11451-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil condition using Komatsu Oil/Fuel & Wear Analysis (KOWA) to detect S4D106-2XFH wear patterns. Check hydraulic oil for contamination in the WB140-2 tank, which holds 24.4 gallons (92.4 liters). Inspect the hydraulic suction strainer at 1,000 hours to prevent pump cavitation. Analyze front and rear axle oils for gear wear. Track coolant concentration using Komatsu Super Coolant AF-NAC to protect the S4D106 cooling system. Monitor transmission oil for thermal degradation.
Corrective & Common Repairs
Address frequent leaks in the hydraulic circuit by inspecting loader arm and backhoe cylinder seals. Replace the hydraulic return filter cartridge if pressure drops. Check the S4D106-2XFH fan belt tension to prevent overheating. Repair exhaust leaks to maintain turbocharger efficiency. Inspect the Load Independent Flow Divider valve block for internal leakage. Replace worn loader arm pins and bushings to restore bucket digging force. Fix brake pedal stroke deviations by adjusting the service brake.
Overhaul & Rebuild Points
Rebuild the S4D106-2XFH engine at 10,000 hours or when compression drops. Replace the hydraulic pump if flow capacity falls below 43.6 GPM (165.0 LPM). Inspect the closed-center hydraulic system relief valves set at 3,000 psi (206.8 bar). Overhaul the front and rear axles when oil contains metal particles. Replace the transmission oil cooler core if cooling efficiency declines. Rebuild the loader boom cylinders if seal failure causes drift.
Seasonal & Environment Servicing
In cold weather, check the battery electrolyte level and ensure the engine oil viscosity matches ambient temperatures. Drain the fuel tank water separator frequently to prevent freezing. In hot weather, clean the radiator and oil cooler fins to prevent S4D106-2XFH overheating. Inspect hydraulic hoses for UV damage. Check tire pressure for varying ground conditions. Grease all lubrication points more frequently in dusty environments to protect the loader and backhoe pivot pins.

Frequently asked questions
What engine does the Komatsu WB140-2 use?
The Komatsu WB140-2 uses a Komatsu S4D106-2XFH turbocharged diesel engine with 93 gross horsepower (69.4 kW) and 87 net horsepower (64.9 kW).
What is the operating weight of the Komatsu WB140-2?
The operating weight ranges from 16,600 to 19,731 pounds (7,529 to 8,949 kg) depending on the configuration and attachment package.
What model replaced the Komatsu WB140-2?
The Komatsu WB140-3 succeeded the WB140-2 in the backhoe loader lineup.
What WB140-2(S/N 140F11451-Up) owners discuss
What engine does the Komatsu WB140-2 (S/N 140F11451-Up) use?
The Komatsu WB140-2 (S/N 140F11451-Up) is equipped with the Komatsu S4D1061FH engine. This engine provides 86 HP net power. The serial number prefix 140F11451-Up distinguishes this specific production run from earlier WB140-2 models (S/N 140F10001-Up) which may have different engine configurations or specifications. The S4D1061FH is a 4-cylinder turbo diesel designed for fuel efficiency and reliable performance in backhoe loader applications.
What are the common hydraulic and transmission behaviors reported for the WB140-2 series?
The WB140-2 series utilizes a closed-center load-sensing hydraulic system with a load-independent flow divider valve block. Operators report that the transmission torque converter pressure should read approximately 40 PSI at idle and 130 PSI at full throttle. A known issue involves the low-pressure side of the transmission valve body; if pressure is higher than the specified 8-10 PSI, it often indicates debris (such as a small piece of metal) obstructing the spool valves, preventing them from closing fully to build proper pressure. Clutch slipping is also a reported issue, typically caused by worn friction plates or improper adjustment of the automatic clutch mechanism.
What undercarriage or wear patterns are typical for this machine type?
The WB140-2 is a wheeled backhoe loader, so it does not have a traditional tracked undercarriage. Wear patterns typically focus on the front and rear axle final drive planetary gear sets and the 4WD engagement system. A common complaint is violent lurching or uneven drive when 4WD is engaged, which may indicate stripped teeth in the front planetary gear sets causing gears to skip. Additionally, the Carraro 4WD system can exhibit cyclical stopping and starting of the front tires if the drive train components are worn or if the tires are mismatched. The rear axle serial number is stamped on a plate on the right side of the axle housing.
What are the known engine quirks per the S4D1061FH series?
A specific quirk reported by owners is a no-crank condition after running the engine for 5 or more hours. Upon shutdown and a short cool-down period (30 minutes), the engine may crank slowly or fail to start, suggesting the engine is exceeding thermal equilibrium. This can lead to mild seizure of components due to compromised oil films. Checking the radiator core for restrictions, ensuring the thermostat operates correctly, and verifying the coolant recovery system are critical steps. Loss of coolant may also indicate a blown head gasket, which can be confirmed via cylinder leakdown or compression tests.
What are the common electrical and sensor issues?
Common electrical issues include starter relay failures and neutral safety switch malfunctions causing no-crank conditions. The WB140-2 uses a common Panasonic relay on the control board for transmission controls; these are known to fail and are often replaced with generic equivalents. Another electrical quirk involves the starter/safety relay inputs: if the input from the alternator and tachometer measures near 0V (e.g., 0.1V) when trying to start, it can prevent the unit from cranking even if other inputs (12V from fuel pump and key switch) are correct. Corroded connections or broken wires at the fuse/circuit board under the steering wheel are also frequent causes of lost power to the LED indicators.
What fluids and capacities are specified for the WB140-2?
For the WB140-2, the radiator coolant capacity is 1.37 gallons (5.19 liters). The recommended engine oil is a high-quality diesel engine oil suitable for the operating conditions, with daily level checks required. For the hydraulic transmission system, Komatsu recommends using Komatsu EO or TO hydraulic oil, or equivalent high-quality hydraulic fluid. The operation and maintenance manual specifies GM DEXRON II® D for certain transmission applications, but operators should verify the specific hydraulic fluid type based on ambient temperatures and manufacturer updates. Always drain hydraulic transmission oil at operating temperature.
What to check when buying a used WB140-2 (S/N 140F11451-Up)?
When purchasing a used WB140-2 with serial number 140F11451-Up, verify the engine is the S4D1061FH and check for signs of thermal stress such as coolant loss or head gasket issues. Test the 4WD system thoroughly for lurching or skipping, which indicates front final drive wear. Check the transmission torque converter pressures (40 PSI idle, 130 PSI full throttle) and inspect the valve body for debris if low pressure is observed. Inspect the starter/safety relay and alternator/tachometer wiring for corrosion or incorrect voltage readings that could cause no-start conditions. Finally, confirm the serial number plate location on the right side of the front main tractor frame to ensure the machine matches the documentation.
