Product Details
ISUZU Power Steering Pump Repair Kit
,OEM Seal & Gasket Kit
,Fits NPR75 NQR71 NQR75 4HK1
The Power Steering Oil Pump Repair Kit with OEM numbers 8-97182111-1 / 8971821111 is a verified direct-fit replacement for ISUZU NPR75, NQR71, NQR75, NQR90, NRR, and NPR-HD trucks equipped with 4HK1 (5.2L) and 4HG1 diesel engines. This kit contains all necessary seals, O-rings, oil seals, and gaskets for the pump interior, designed to repair oil leakage, insufficient pressure, or abnormal noise caused by aged or worn seals — restoring proper power steering system operation without replacing the entire steering pump assembly.
The power steering oil pump is the core power source of the hydraulic power steering system, responsible for converting engine mechanical energy into hydraulic pressure to drive the steering gear for effortless steering. When internal seals age or wear, it leads to heavy steering, abnormal noise, and fluid leakage. Timely replacement of the repair kit restores proper steering system operation.

⚠️ Important:
- Model Confirmation: This repair kit primarily fits NPR75, NQR71, NQR75, NQR90, NRR, and NPR-HD models, covering 1998–2010 model years with 4HK1 (5.2L) and 4HG1 engines equipped with hydro brake booster. Variations may exist across model years or configurations. Verify the original steering pump assembly number before installation.
- Repair Kit vs. Assembly: This product is a seal repair kit (gaskets, O-rings, oil seals, etc.), not including the steering pump housing, rotor, stator, or other metal components. If internal mechanical components are severely worn, replacing the complete pump assembly is recommended.
- Pre-Installation Verification: Please provide the VIN or original steering pump assembly number for precise fitment confirmation.

⚠️ Important: Power steering oil pump repair kit installation involves steering hydraulic system disassembly. Professional installation by a qualified technician is recommended. Thoroughly clean the steering pump interior before installation and inspect the pump body, rotor, stator, and pressure plate for wear. If metal components are severely worn or scored, replacing seals alone will not restore sealing performance; the complete steering pump assembly must be replaced.
- Disconnect power: Disconnect the negative battery terminal to prevent electrical short circuits.
- Drain hydraulic fluid: Drain hydraulic fluid from the steering reservoir and lines using a suction tool or drain valve.
- Remove steering pump: Remove the drive belt, inlet/outlet hose fittings, and mounting bolts; remove the steering pump from the engine.
- Disassemble pump: Disassemble the steering pump per workshop manual sequence, extract old seals, gaskets, and O-rings. Note the installation position and orientation of each seal.
- Clean components: Thoroughly clean the pump body, rotor, stator, and pressure plate with dedicated cleaner, removing old seal residue and oil.
- Install new seals: Apply appropriate hydraulic fluid to seals, install new O-rings, oil seals, and gaskets in the correct orientation.
- Reassemble pump: Reassemble the steering pump in reverse order of disassembly, tighten fixing bolts to specified torque.
- Install steering pump: Reinstall the pump to the engine, connect inlet/outlet hoses and drive belt, fill with specified hydraulic fluid.
- Bleed and test: Start the engine, turn the steering wheel left and right to bleed air from the system, check fittings for leakage, confirm proper power steering assist.
- Every 20,000 km or 12 months: Check steering fluid level and quality, inspect pump and lines for leakage.
- Every 50,000 km: Replace steering hydraulic fluid, check steering pump operating condition.
- When heavy steering, abnormal noise, or fluid leakage is detected: Inspect steering pump seal condition promptly and replace the repair kit if necessary.
