Komatsu WB97S-2(S/N 97SF10431-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WB97S-2 is a 4-wheel steering backhoe loader manufactured from 2000 to 2005. It is powered by a Komatsu S4D106-1FA turbocharged diesel engine producing 97.9 net horsepower (73.0 kW) at 2200 RPM. The machine has an operating weight of 8001.4 kg (17640 lbs) and a standard bucket capacity of 1.1 m³ (1.44 cu yds). It features a full powershift transmission with 4 forward and 4 reverse gears, and 4-wheel drive. Configurations offered include standard and extended reach loader arms, with variations in digging depth and loading height depending on the arm length. The WB97S-2 succeeded the WB97S-1 and was later replaced by the WB97S-5.
Across its generation, the WB97S-2 maintained a consistent S4D106-1FA engine platform while offering configuration variations in arm length and bucket size to suit municipal and utility work. The machine remains significant in the used and parts market due to its robust Komatsu powertrain and widespread availability of aftermarket components. Its 4-wheel steering capability and compact turning radius make it a staple in confined urban environments. The serial prefix 97SF denotes the WB97S-2 series, distinguishing it from the WB97R-2 series which uses different engine and emission configurations.

Servicing the WB97S-2(S/N 97SF10431-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor S4D106-1FA engine oil pressure and temperature during operation. Analyze hydraulic oil samples every 500 hours to detect pump wear in the variable displacement axial piston system. Check transmission oil for metal particles indicating gear wear. Inspect coolant pH levels to prevent corrosion in the S4D106-1FA cooling jacket. Track fuel filter restriction to predict injector pump strain. Monitor brake fluid contamination to ensure safe stopping power.
Corrective & Common Repairs
Address S4D106-1FA turbocharger shaft play by replacing the turbo assembly if excessive. Replace hydraulic filter cartridges if pressure differential exceeds limits. Fix fuel system air leaks at the filter housing or fuel pump to prevent hard starting. Repair leaking front axle seals which are common failure points. Replace worn loader arm pins and bushings to restore bucket breakout force. Fix steering ram leaks that cause wheels to lock in crab steering mode.
Overhaul & Rebuild Points
Rebuild the S4D106-1FA engine at 10,000 hours or when compression drops below spec. Replace injector assemblies if spray pattern is poor or leakage occurs. Overhaul the full powershift transmission if gear slippage or overheating persists. Rebuild the hydraulic pump if flow drops below 165.0 LPM at 2200 RPM. Replace final drive planetary gears if noise or oil leakage indicates internal wear. Rebuild the steering axle seals to prevent fluid loss and contamination.
Seasonal & Environment Servicing
Drain the fuel tank condensate before winter to prevent freezing in the S4D106-1FA fuel system. Use low-temperature hydraulic oil if operating below -10°C. Check the battery electrolyte level and charge status in cold weather. Inspect the cooling system for leaks before summer high-load operation. Clean the radiator and A/C condenser fins more frequently in dusty environments. Verify the operation of the cab heater and defroster for operator comfort.

WB97S-2(S/N 97SF10431-Up) serial number reference
The PIN plate is riveted to the right-hand side of the cab on the lower frame, typically just behind the front idler or beneath the operator's window. The prefix is the first four characters of the 17-character ISO PIN (e.g., 97SF), which identifies the model family and generation.
| Prefix | Identifies | Notes |
|---|---|---|
| 97SF | WB97S-2 | Serial break at 97SF10431; covers WB97S-2 S/N 97SF10431-Up. Confirmed by shop manual and parts catalog listings. |
Frequently asked questions
What engine does the Komatsu WB97S-2 (S/N 97SF10431-Up) use?
The Komatsu WB97S-2 (S/N 97SF10431-Up) uses the Komatsu S4D106-1FA turbocharged diesel engine.
What is the operating weight of the Komatsu WB97S-2?
The operating weight of the Komatsu WB97S-2 is 8001.4 kg (17640 lbs).
What model replaced the Komatsu WB97S-2?
The Komatsu WB97S-5 replaced the WB97S-2 series.
What WB97S-2(S/N 97SF10431-Up) owners discuss
What engine powers the Komatsu WB97S-2 with serial number 97SF10431 and up?
The machine uses a Komatsu 97.8 HP turbocharged engine. This configuration is specific to the WB97S-2 series; other variants like the WB97R-2 may use different powerplants. The engine meets Stage 2 emissions standards for this generation.
What are the common electrical causes for a 'No Go' condition (Error E1) on the WB97S-2?
A blinking key symbol at the coupling glove and inability to drive forward or backward typically indicates an electrical fault. Common causes include a failed Carraro transmission control unit located near the steering column, faulty seat weight sensor wiring, or stuck travel direction switches behind the dashboard panel. Mechanics report that replacing the seat actuator often fails to resolve the issue if the transmission controller is the root cause.
What are the typical hydraulic and steering behaviors for this machine?
The WB97S-2 utilizes a full powershift transmission with electronic control and 4-wheel drive. The hydraulic system employs a variable displacement axial piston pump. Users note that steering functions can become erratic if the electronic control module fails or if there is an EEPROM data corruption, leading to one axle steering while the other operates oppositely. The machine is generally described as having good traction, though it may struggle in heavy clay conditions. Fluid specifications should follow Komatsu EO or TO standards for the hydraulic system.
What wear patterns or maintenance items are critical for the WB97S-2?
The hydraulic oil cooler (core size 427 x 518 x 50 mm) is a known wear item shared with the WA140-2 and WB91R-2. The transmission and final drives require specific greasing intervals. The machine has an operating weight of approximately 8 tons. Regular inspection of the seat sensor wiring and the transmission controller connectors is recommended to prevent drive loss. Check the steering cylinder seals for leaks, as these are common failure points in high-hour units.
What should be checked when buying a used WB97S-2 (S/N 97SF10431-Up)?
Verify the serial number prefix to ensure it matches the 97SF10431-Up range, as earlier serials (e.g., 97SF10001-Up) may have different component specifications. Test the transmission controller for error codes and ensure the seat safety switch does not trigger false 'No Go' errors. Check the hydraulic oil cooler for internal leaks or blockage. Inspect the joystick potentiometer for open circuit errors, which can cause erratic control behavior. Confirm the engine meets the required Stage 2 emissions tier for your region. Have your dealer verify the transmission controller health and serial range compatibility.
How does the WB97S-2 compare to the WB97R-2 in terms of reliability and parts?
Operators often note that while the WB97S-2 is robust, parts availability can be more challenging compared to competitors like JCB or CAT. The WB97S-2 uses a Komatsu engine, whereas the WB97R-2 may use a different powerplant (e.g., Yanmar or Komatsu variants depending on the specific serial break). The WB97S-2 is generally considered reliable with fewer major failures if maintained, but minor electrical gremlins (seat sensors, controllers) are common. The WB97R-2 shares some hydraulic components but differs in engine and transmission tuning. Consult the specific shop manual for the serial range to confirm part interchangeability.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
