Assembly
Check all mating surfaces. Replace any parts with
scratches or burrs that could cause leakage. Wash all
metal parts in clean solvent. Blow them dry with pressur-
ized air. Do not wipe parts dry with paper towels or cloth.
Lint in a hydraulic system will cause damage.
Note: Always use new seals when reassembling the
steering control unit.
IMPORTANT: During reassembly, lubricate the new
seals with petroleum jelly. Also lubricate machined
surfaces and bearings with clean hydraulic fluid.
1. Install the quad seal:
A. Put one of the bearing races and sleeve into the
housing.
B. Together, the housing and bearing race create a
groove into which the quad seal will be installed.
C. Hold the bearing race tightly against the input end
of the housing by pushing on the gerotor end of the
sleeve.
D. Fit the quad seal into its seat through the input end
of the housing. Be sure the seal is not twisted.
E. Remove the sleeve and bearing race.
2. Lubricate and install the dust seal (Fig. 62).
