SPINDLE DISASSEMBLY

CAUTION: Do not attempt disassembly of the spindle assembly which contains the rotary valve. Individual replacement parts are NOT available for this assembly. It must be treated as a single component.

CLEANING AND INSPECTION

CLEANING

Wash all parts individually in clean solvent and dry thoroughly. All non-metallic parts should be discarded and replaced with new.

INSPECTION

Visually inspect all parts carefully paying particular attention to:

1.Bearings and bearing surfaces including inner and outer races and balls.

2.Sector gear and piston teeth.

3.Output and input shaft.

4.Exterior of spindle and interior of piston and recirculating balls.

5.Exterior of piston and housing bore.

NOTE: Minor scuffing of the piston exterior and housing bore can be considered normal. If deep scoring is detected, the affected parts should be replaced as leakage will occur and steering control and reaction will be affected. Do not attempt honing or boring of these parts as leakage rates will increase.

6.Pitman arm.

7.Housing and mounting lugs.

8.Valve body and porting. Parts found broken, cracked, distorted or fatigued must be replaced. Cause for the replacement of any part should be investigated and corrected to prevent reoccurrence.

IX. REASSEMBLING THE POWER STEERING UNIT

To ensure a correct fault-free operation of the power steering unit, after all parts have been cleaned and faulty ones replaced, the following assembly procedure should be followed. The appropriate maintenance kit or kits should be obtained prior to assembly. Should any of the 17 ball bearing balls require replacement, replace them all at once; proceed similarly in case any of the 26 recirculating balls need replacement. Failure to follow this procedure strictly may result in a faulty operation of the power steering unit.
