Seal Replacement Recommendations
Lip Seals
Lip seals seal the rotating shafts. The lip seals require
special treatment. Lip seals are used on the hydraulic
pump shaft of the power steering pump. When the
lip seals leak complete the following steps:
1. Inspect the sealing surfaces.
2. Thoroughly clean the sealing sµrfaces.
3. Replace the seal(s).
Replace the shaft if you find pitting. If there is slight
corrosion in the lip seal contact zone, clean the surface
of the shaft with crocus cloth. Replace the shaft only
if you cannot stop the leakage by smoothing the
shaft with crocus cloth.
0-Ring Seals
When you remove a part which forms a sealing
surface for an 0-ring complete the following steps:
1. Remove the original 0-ring seal.
2. Replace the original 0-ring seal with a new
0-ring seal.
Lubricate all of the new 0-ring seals with power
steering fluid in order to ease the installation.
