GENERAL DESCRIPTION AND SYSTEM OPERATION

Power Steering Pump

General Description

The pump has a remote fluid reservoir. A pressure-relief valve inside the flow control valve limits pump pressure.

Seals

Seal Replacement

Lip seals, which seal the rotating shafts, are used on the driveshaft of the pump. This type of seal requires special treatment. When leakage occurs in this area, always replace the seal after inspecting and thoroughly cleaning the sealing surfaces. If the corrosion in the lip seal contact zone is slight, clean the surface of the shaft with a crocus cloth. Replace the shaft only if the leakage cannot be stopped by first smoothing the shaft with the crocus cloth.
