Power Steering Oil Pump Assembly 1-19500433-0 1195004330 For ISUZU 6HE1 Engine

The Power Steering Oil Pump Assembly (OEM Numbers: 1-19500433-0 / 1195004330) is a premium-quality, direct replacement hydraulic pump designed specifically for ISUZU trucks equipped with 6HE1 diesel engines. This complete assembly serves as the heart of the hydraulic steering system, drawing power steering fluid from the reservoir, pressurizing it, and delivering it to the steering gear box to reduce driver effort and improve vehicle maneuverability.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function
• High-Efficiency Pumping: Precision-machined internal gear set provides consistent fluid flow and pressure
• Durable Construction: High-strength aluminum housing and hardened internals withstand high pressures and temperatures
• Leak-Proof Design: Precision seals and machined mating surfaces prevent fluid leaks and maintain system pressure
• Restores Steering Assist: Eliminates stiff steering, whining noise, and loss of assist caused by a worn pump
• Direct Replacement: Matches OE mounting flange, pulley, and fluid line connections for simple installation
• Long Service Life: Engineered for heavy-duty commercial truck applications
• Essential Safety Component: Critical for reliable steering control and driver safety
• Cost-Effective Repair: Affordable replacement that restores proper steering performance without costly modifications

This power steering pump assembly is specifically designed for ISUZU heavy-duty trucks and commercial vehicles. Common applications include:

• ISUZU FSR (Medium-Duty Trucks)
• ISUZU FTR (Medium-Duty Trucks)
• ISUZU FVR (Heavy-Duty Trucks)
• ISUZU 6HE1 Engine Specifications:
  • 6-Cylinder, Inline Diesel
  • Displacement: 7.2L
  • Application: Heavy-duty trucks, buses, and industrial equipment

Also compatible with various ISUZU models using the 6HE1 engine and the same power steering pump configuration.

Professional mechanic or steering specialist installation recommended:

1. Ensure engine is cool - Allow the engine to cool completely before working
2. Disconnect battery - Always disconnect the negative terminal before working
3. Drain power steering fluid - Place a container below the pump and drain the fluid
4. Remove the drive belt - Loosen the tensioner and remove the belt from the pump pulley
5. Disconnect fluid lines - Disconnect the high-pressure and return lines from the pump; cap openings to prevent contamination
6. Remove mounting bolts - Unbolt the old pump from its mounting bracket
7. Remove old pump - Carefully remove the old pump; note the orientation and pulley position
8. Clean mounting area - Remove dirt, oil, and debris from the mounting bracket and fluid lines
9. Install new pump - Position the new pump on the mounting bracket; align bolt holes
10. Install mounting bolts - Hand-start and tighten bolts to manufacturer torque specifications
11. Reconnect fluid lines - Attach the high-pressure and return lines; tighten fittings to specification
12. Install drive belt - Reinstall the drive belt and adjust tension to specification
13. Fill with fluid - Fill the reservoir with the specified power steering fluid
14. Bleed the system - Start the engine and turn the steering wheel lock-to-lock several times to bleed air; top up fluid as needed
15. Check for leaks - Inspect all connections for fluid leaks
16. Road test - Test drive to verify proper steering assist and no abnormal noise
