Seal Replacement

Lip seals, which seal rotating shafts, require special treatment. They are used on the steering gear at the pinion shaft and on the pump drive shaft. When leakage occurs in these areas, always replace the seal after inspecting and thoroughly cleaning the sealing surface. If corrosion in the lip seal contact zone is slight, clean the surface of the shaft with crocus cloth. Replace the shaft only if very severe pitting is found, such that leakage cannot be stopped by cleaning the shaft, and then only if the information under Power Steering Gear, Testing and Inspection notes the shaft to be replaceable.
