Lip Seals
Lip seals, which seal rotating shafts, require special treatment. This type of seal is used on the hydraulic pump shaft and the pinion shaft of the
steering gear. When leakage occurs in this area, always replace the seal or seals, after inspecting and thoroughly cleaning the sealing surfaces. Replace the shaft if pitting is found. If corrosion in the lip seal contact zone is slight, clean the surface of the shaft with crocus cloth. Replace the hydraulic pump shaft of complete gear only if the leakage cannot be stopped by smoothing with crocus cloth first.
