The lip seals require special treatment. The lip seals seal the rotating shafts. This type of seal is used on the following components:

    • The steering gear at the pinion shaft
    • On the drive shaft of the pump

When a leak occurs in this area, complete the following steps:

  1. Inspect the sealing surface.
  2. Thoroughly cleaning the sealing surface.
  3. Replace the seal.

Replace the shaft only if severe pitting is found. If the corrosion in the lip seal contact zone is slight, clean the surface of the shaft using a crocus cloth. Replace the shaft only if the crocus cloth does not stop the leakage by smoothing.
