🔌 Function

Pressurises the steering system's oil so the helm effort is assisted rather than being carried entirely by the person at the wheel.

⚠️ Common Signs of Failure

• Steering going heavy, especially at low speed or hard over
• Whining or groaning that rises as the wheel is turned
• Oil weeping from the pump body or shaft seal
• Foaming or milky oil, showing air is being drawn in
• Assistance fading away as the system warms up

🛠️ Service Notes

• Loss of steering assistance is a handling problem before it is a comfort problem, so treat a failing pump as a job to do before the next passage rather than after it
• Check the oil level, the suction hose and the reservoir before condemning the pump - the reservoir kit 855544 and the sealing kit 855735 are listed here for the same system
• Bleed the system thoroughly after fitting and recheck the level once the trapped air has worked out
