Lip seals seal the rotating shafts. The lip seals require
special treatment. Lip seals are used on the steering gear in the following
locations:
• | On the pump drive shaft |
When a leak occurs in these areas, perform the following steps:
- Inspect the sealing surface.
- Clean the sealing surface.
- Replace the seal.
If corrosion in the lip seal contact zone is slight, clean the surface
of the shaft using a crocus cloth. Replace the shaft only under the following
conditions:
• | You find such severe pitting that cleaning the shaft will not
stop the leak |
• | Unit Repair procedures indicate that the shaft is replaceable |
