Komatsu WB97S-2(S/N 97SF10281-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 HP (73.0 kW) at 2000 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 4WD and 4-wheel steering. Configurations include standard and extended reach loader arms and backhoe booms. The WB97S-2 succeeded the WB97S-1 and was later replaced by the WB97S-5.
Across the WB97S series, the primary change was the transition from Stage 2 emissions compliance in the WB97S-2 to Tier 3/Stage IIIa in later models like the WB97S-5, which also updated the engine to the S4D104E series. The WB97S-2 remains significant in the used market due to its robust S4D106-1FA engine and simple hydraulic system, which are easier to service than modern emissions-heavy variants. Its 4-wheel steering capability and compact turning radius make it highly valued for municipal and utility work where space is limited. Parts availability remains strong due to the machine's widespread use in Europe and North America.

Servicing the WB97S-2(S/N 97SF10281-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor hydraulic oil temperature and pressure at the pump outlet. Check the hydraulic oil filter restriction indicator regularly. Analyze hydraulic oil samples every 500 hours for viscosity and contamination. Inspect the fuel water separator for water accumulation. Check the engine oil pressure at idle and rated speed. Monitor the coolant concentration and pH levels to prevent corrosion in the S4D106-1FA engine block.
Corrective & Common Repairs
Replace the hydraulic oil filter cartridge if the restriction indicator shows red. Clean the radiator and A/C condenser fins if overheating occurs. Inspect the fuel filter and bleed the system if the engine starts irregularly. Check the rear steering ram for leaks and ensure it returns to neutral. Replace worn loader and backhoe pins and bushings to maintain alignment. Inspect the transmission oil for metal particles indicating gear wear.
Overhaul & Rebuild Points
Inspect the turbocharger shaft play and seals at 2000 hours. Check the valve clearance and adjust if the engine runs roughly. Inspect the injector assembly for leaks and spray pattern. Check the hydraulic pump pressure relief valve settings. Inspect the final drives for oil leaks and bearing noise. Replace the fan belt if cracks or fraying are visible. Check the engine mounts for deterioration.
Seasonal & Environment Servicing
Drain the fuel tank condensate before starting in temperatures above 0°C. Drain the fuel tank at the end of work if temperatures drop below 0°C to prevent freezing. Use low-pressure water or steam to clean the radiator and condenser in dusty environments. Check the battery electrolyte level and terminal tightness in cold weather. Inspect the cab heater and defroster operation. Ensure the coolant concentration is adequate for the local climate.

| CA441 | Battery voltage too low | Discharged battery, failing alternator, or parasitic electrical drain | Test battery state of charge and load capacity; verify alternator charging output |
| CA442 | Battery voltage too high | Faulty voltage regulator in the alternator or wiring short in the charging circuit | Inspect the alternator voltage regulator and wiring harness for shorts; replace the alternator if necessary |
| CA122 | Intake air pressure sensor feedback voltage too high | Faulty intake pressure sensor, shorted wiring, or actual over-boost condition | Verify the intake pressure sensor operation and wiring integrity; check for airflow restrictions |
| CA123 | Intake air pressure sensor feedback voltage too low | Sensor short circuit, open circuit in wiring, or significant airflow restriction | Check the sensor connector for corrosion or damage; inspect the intake system for blockages |
| CA153 | Intake air temperature sensor feedback voltage too high | Faulty intake air temperature (IAT) sensor or open circuit in the sensor wiring | Test the IAT sensor resistance and replace if out of specification; check wiring continuity |
| CA154 | Intake air temperature sensor feedback voltage too low | Shorted intake air temperature sensor or shorted wiring harness | Inspect the sensor and wiring for short circuits; replace the sensor if the fault persists |

Frequently asked questions
What engine does the Komatsu WB97S-2 use?
The Komatsu WB97S-2 uses a Komatsu S4D106-1FA turbocharged diesel engine with 4 cylinders and a displacement of 4413.0 cc (269.3 cu in). It produces 97.9 net HP (73.0 kW) at 2000 RPM.
What is the operating weight of the Komatsu WB97S-2?
The operating weight of the Komatsu WB97S-2 is 8001.4 kg (17640 lbs). This weight varies by configuration, attachment package, and counterweight setup.
What model replaced the Komatsu WB97S-2?
The Komatsu WB97S-5 replaced the WB97S-2. The WB97S-5 features updated emissions compliance (Tier 3/Stage IIIa) and uses the Komatsu S4D104E-1 or S4D104E-3 engine series.
What WB97S-2(S/N 97SF10281-Up) owners discuss
What is the primary cause of 'No Go' (E1) errors on the WB97S-2 after seat actuator replacement?
The Carraro transmission control unit (TCU) located near the steering column often fails, preventing forward and reverse engagement. This is distinct from seat safety switch wiring issues. Verify the TCU status before inspecting seat sensors or travel switches. Have your dealer verify the specific error code and TCU functionality.
What engine powers the WB97S-2 (S/N 97SF10281-Up)?
The machine uses a Komatsu 97.8 HP turbocharged engine. Factory spec sheets for this serial range confirm the Komatsu engine designation rather than Perkins or Yanmar variants found in earlier or different series. Verify the exact engine model plate on the specific unit.
What are common electrical or sensor issues reported by operators?
Operators report joystick reset issues requiring specific codes after battery disconnection. Steering function errors may involve EEPROM data corruption in control modules. The key symbol at the coupling glove blinking indicates a drive lockout fault, often electrical in nature. Check joystick potentiometers for open circuits, particularly rear potentiometer faults.
What wear patterns or maintenance items are typical for this machine type?
The WB97S-2 utilizes a full powershift transmission with electronic control and 4-wheel drive. Hydraulic systems use variable displacement axial piston pumps. Maintenance intervals include every 250 hours of operation. Check stabilizer types and ground clearance for wear. The machine is noted for comfort and operational simplicity but requires attention to hydraulic oil cooler integrity.
What are the key specifications for the WB97S-2 (S/N 97SF10281-Up)?
Operating weight is approximately 8 tons (8,000 kg). Transport length is 5.5 meters. Bucket capacity is 1.1 cubic meters. Tear-out force is 37.8 kilonewtons. Dredging depth is 6.1 meters. Maximum discharge height is 3.4 meters. These values apply to the standard configuration for this serial range.
What should be checked when buying a used WB97S-2 (S/N 97SF10281-Up)?
Verify the serial number matches the 97SF10281 and up range to ensure correct shop manual applicability. Check the Carraro transmission control unit for error codes if drive functions are intermittent. Inspect the hydraulic oil cooler for leaks or damage. Confirm the joystick potentiometers are functioning correctly. Test the seat safety switch wiring and interlock system. Have your dealer verify the transmission control unit and hydraulic pump pressures.
How does the WB97S-2 compare to similar utility machines in terms of reliability?
Operators describe the machine as having optimal quality and repairability. It is considered comfortable and efficient. While complex electronics can be a point of failure, the mechanical components are robust. Parts availability is generally good, though specific electronic modules may require specialized service. Compare against JCB and CAT for parts availability in specific regions.
