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 a very 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.
