PITMAN SHAFT SEALS
INSTALL
NOTE: Removal of seals can be accomplished with
steering gear in car, using hydraulic pressure from gear
assembly to force seals out ofpitman shaft bore.
1. Raise car and remove pitman arm retaining nut and
lockwasher.
2. Remove pitman arm using tool J 5504-1.
3. Remove pitman shaft outer dust seal retaining ring,
using Truarc pliers.
4. Remove outer dust seal, using screwdriver or similar
tool and place a cloth around housing and pitman
shaft to absorb oil leakage from seal bore.
5. Hold a clean dry pan under gear housing and with
engine running, momentarily turn steering gear to
extreme left posinon tbr not more than two seconas.
This will build up pressure on upper side of piston and
in pitman shaft chamber, forcing seals and inner
back-up washer out of bore.
NOTE: If pressure of oil does not remove seals, turn off
engine, remove steering gear from car, and disassemble
gear, refer to procedures outlined farther in this section.
6. Clean seal bore of housing, pitman shaft and inspect
housing bore for any burrs which might damage seals
during installation.
7. Wrap a piece of thin tape around splines of pitman
shaft, this will prevent damage of seals during
installation. Use only one layer of tape to allow for
clearance of seals to pass over taped area.
8. Lubricate seals thoroughly and install seals using
tool J 6219. Install inner single lip seal, then backup
washer and retaining ring. Be sure that inner seal does
not bottom in housing bore. Install seals only far
enough to provide clearance for backup washers and
retaining ring.
