15. Pitman Shaft Seal Replacement
(Gear on Car)
When inspection indicates that a pitman shaft
seal is leaking, it may be replaced without r e -
moving gear from car. Proceed as follows:
a. Removal
1. Raise front end of car and place jack stands
near outer ends of lower suspension arms.
2. Remove pitman arm retaining nut and lock
washer and break pitman arm loose from pitman
shaft, using Pitman Arm Puller, J-9172.

using Snap Ring Pliers, J-4245 (#3).
6. Place a container under steering gear to
catch fluid. Start engine and turn steering gear
to extreme left turn position. Oil pressure will
force seals and back-up washers out of gear
housing. To prevent oil loss and pump wear, do
not hold wheel in left turn position for more than
a few seconds at a time. Shut off engine as soon
as seals are forced out.
7. Inspect seals for damage. If O.D. appears
scored, inspect housing for burrs and remove be-
fore attempting new seal installation.
b. Installation
1. Clean end of pitman shaft bore to prevent
entrance of dirt into housing or damage to seals as
they are installed.

prevent damage to seals as they are installed. Use
only one layer of tape to assure adequate clear-
ance for seals.
