Servicing the WB140-2(S/N 140F11531-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor S4D106-2XFH engine oil for soot loading and fuel dilution. Analyze hydraulic oil for water ingress in the closed-center load-sensing system. Check front and rear axle oil for gear wear particles. Inspect transmission oil for clutch material. Use Komatsu EO or equivalent for engine oil. Use Komatsu TO or equivalent for hydraulic systems. Track KOWA oil analysis trends to predict injector pump or bearing failures.
Corrective & Common Repairs
Address S4D106-2XFH injector leaks and glow plug failures common in cold climates. Replace worn steering cylinder seals to prevent hydraulic fluid loss. Repair cracked exhaust manifolds from thermal cycling. Fix hydraulic pump shaft seals to maintain relief valve pressure at 3000 psi. Replace worn loader arm pivot pins and bushings. Repair brake pedal stroke issues by adjusting service brake components.
Overhaul & Rebuild Points
Rebuild S4D106-2XFH engine at 10,000 hours or upon loss of compression. Inspect turbocharger shaft play and replace if excessive. Overhaul hydraulic pump and motor if flow drops below 43.6 GPM. Rebuild front and rear axles when oil contamination exceeds limits. Replace loader boom cylinders if scoring is present. Recondition steering unit if internal leakage causes drift.
Seasonal & Environment Servicing
Use GM DEXRON II® D fluid for hydraulic systems in cold weather. Check radiator and intercooler fins for debris accumulation. Inspect battery electrolyte level and charge state in winter. Use Komatsu Super-coolant AF-NAC for extended corrosion protection. Lubricate all grease points more frequently in dusty conditions. Check brake fluid level and replace if contaminated with water.

Frequently asked questions
What engine does the WB140-2 use?
The WB140-2 uses a Komatsu S4D106-2XFH turbocharged diesel engine with 4 cylinders, 268.6 cu in (4401.6 cc) displacement, and 93 HP gross power.
What is the operating weight?
Operating weight varies by configuration from 16,600 to 19,731 lbs (7,525 to 8,949 kg).
What model replaced the WB140-2?
The WB140-3 replaced the WB140-2 in Komatsu's backhoe loader lineup.
What WB140-2(S/N 140F11531-Up) owners discuss
What are the common powertrain and hydraulic behaviors reported for the Komatsu WB140-2?
Operators report that the machine utilizes a closed-center load-sensing hydraulic system. A known powertrain issue involves the transmission torque converter; low-pressure readings can indicate a blockage in the valve body spools. Specifically, debris trapped in the spools can prevent proper pressure buildup. The transmission clutch may also slip due to worn friction plates or improper adjustment of the automatic clutch mechanism, requiring inspection of the clutch pack for wear or oil contamination. The 4WD system can exhibit violent lurching or uneven drive when engaged, often attributed to issues in the front drive train or final drive planetary gear sets rather than tire size or condition. The machine features a Load Independent Flow Divider valve block to manage hydraulic speeds. (Source: published references, Komatsu WB140-2N Operation & Maintenance Manual, Komatsu WB140-2 Service Shop Repair Manual)
What engine quirks or thermal issues are associated with the WB140-2 series?
The WB140-2 is equipped with a Yanmar turbo diesel engine. A common thermal issue involves the engine exceeding its optimal operating temperature (thermal equilibrium) after running for five or more hours. This can cause components to expand beyond normal tolerances, leading to mild seizure and slow cranking or hard starting upon shutdown. The issue resolves after the engine cools down. Contributing factors include restricted radiators, incorrect coolant types, or faulty thermostats. Coolant loss may also indicate a blown head gasket, which can be verified via cylinder leakdown or compression tests. (Source: TractorByNet, Komatsu WB140-2N Motor issues thread)
What are the typical undercarriage or wear patterns for this machine type?
The WB140-2 is a wheeled backhoe loader, so it utilizes tires rather than track undercarriage. Wear patterns often focus on the front axle and final drive planetary gear sets, which may suffer from stripped teeth causing skipping or slamming noises during 4WD operation. The rear axle serial number is stamped on a plate on the right side of the axle housing. Hydraulic cylinder seals on the backhoe boom, arm, and stabilizers are common wear items, with specific seal kits available for different serial number breakpoints. (Source: Komatsu WB140 Backhoe Cylinder Seal Kits, Komatsu WB140-2N Operation & Maintenance Manual, published references)
What are the common electrical or sensor issues for the WB140-2?
Electrical issues frequently manifest as no-crank conditions due to starter relay failures or neutral safety switch malfunctions. The starter/safety relay has three inputs: 12V from the fuel pump circuit, 12V from the key switch (passing through the neutral relay), and a signal from the alternator/tachometer. A low voltage reading (e.g., 0.1V) from the alternator circuit can prevent the starter from engaging. Additionally, the control board uses common Panasonic relays for transmission controls that can fail; these are soldered into the black box on the firewall. Corroded connections or broken wires in the fuse/circuit board under the steering wheel can also cause power loss to LED indicators. (Source: published references, Komatsu WB140-2N wont turn over thread, Komatsu WB140-2 Backhoe: Parts Manual)
What specific items should be checked when buying a used WB140-2 (S/N 140F11531-Up)?
For units with serial number 140F11531 and up, verify the engine cooling system for restrictions and proper coolant type, as thermal equilibrium issues are common. Check the transmission torque converter pressure (low side should be around 8-10 PSI; high side around 130 PSI at full throttle) and inspect the valve body spools for debris. Test the 4WD engagement for lurching or skipping, which indicates front final drive wear. Inspect the starter relay and alternator signal circuit for no-crank conditions. Check for coolant loss which may indicate a head gasket failure. Ensure the neutral safety switch and starter relay are functioning correctly. (Source: Komatsu WB140-2 Service Shop Repair Manual, published references, Komatsu WB140-2N Operation & Maintenance Manual)
What are the recommended fluids and capacities for the WB140-2?
The radiator coolant capacity is 1.37 gallons (5.19 liters). The recommended radiator coolant is GM DEXRON II® D. Engine oil must be selected carefully, with daily checks recommended. Hydraulic transmission oil must be drained at operating temperature. (Source: Komatsu WB140-2N Operation & Maintenance Manual, Oil and coolant capacity quick reference guide)
What safety-critical fixes or verifications are required for the WB140-2?
Proper service and repair are extremely important for safe operation. The machine is equipped with a safety lock for the raised loader arm that must be engaged when parked. The neutral safety switch must function correctly to prevent unintended movement during starting. The 4WD system lurching issues can cause cascading damage to the drive train and should be addressed promptly.
