often be replaced without removing the gear assembly
from the vehicle as follows:
1. Remove pitman nut and disconnect pitman arm
from pitman shaft using Puller J-6632.
CAUTION: Do not hammer on the end of
Puller Tool J-6632.
2. Thoroughly clean end of pitman shaft and gear
housing, then tape splines on end of pitman shaft
to insure that seals will not be cut by splines during
assembly.
NOTE: Only one layer of tape should be
used; an excessive amount of tape will not
allow the seals to pass over it, due to the close
tolerance between the seals and the pitman
shaft.
3. Remove pitman shaft seal retaining ring with Snap
Ring Pliers J-4245.
4. Start engine and turn steering wheel fully to the left
so that oil pressure in the housing can force out
pitman shaft seals. Turn off engine.
NOTE: Use suitable container to catch oil
forced out of gear. This method of removing
the pitman shaft seals is recommended, as it
eliminates the possibility of scoring the
housing while attempting to pry seals out. If
pressure of oil does not remove seals, turn off
engine, remove the steering gear and remove
the seals as outlined previously in this
section.
5. Clean the end of housing thoroughly so that dirt
will not enter housing with the installation of the
new seals.
6. Lubricate the seals thoroughly with Power Steering
Fluid to install seals with Installer J-6219. Install the
inner single lip seal first, then a back-up washer.
Drive seal in far enough to provide clearance for
the outer seal, back-up washer and retaining ring.
Make sure that the inner seal does not bottom on
the counterbore. Install the outer double lip seal
and the second back-up washer in only far enough
to provide clearance for the retaining ring. Install
retaining ring.
7. Fill pump reservoir to proper level. Start engine
and allow engine to idle for at least three minutes
without turning steering wheel. Turn wheel to left
and check for leaks.
8. Remove tape and reconnect pitman arm.
CAUTION: The pitman arm to steering gear
nut is an important attaching part in that it
could affect the performance of vital compo
nents and systems, and/or could result in major
repair expense. It must be replaced with one of
the same part number or with an equivalent
part if replacement becomes necessary. Do not
use a replacement part o f lesser quality or
substitute design. Torque values must be used
as specified during reassembly to assure proper
retention of this part.
GEAR ASSEMBLY
1. Lubricate the worm, lower thrust bearing and the
two thrust washers with Power Steering Fluid, then
install one thrust washer, the bearing, and the other
thrust washer over the end of the worm (fig. 54).
2. Lubricate the valve body teflon rings and a new
stub shaft cap "O" ring with Power Steering Fluid.
Install the stub shaft cap "O" ring in the valve
body so it is seated against the stub shaft cap. Align
the NARROW NOTCH in the valve body with the
pin in the worm, then install the valve and stub
shaft assembly in the gear housing (fig. 55). Apply
pressure to the VALVE BODY when installing. If
pressure is applied to the stub shaft during
installation, the stub shaft may be forced out of the
valve body (fig. 56).
NOTE: The valve body is properly seated
when the oil return hole in the housing is
entirely uncovered (fig. 57).
3. Lubricate a new adjuster plug "O" ring with Power
Steering Fluid and install in groove on adjuster
plug. Place Seal Protector J-6222 over the stub
shaft, then install the adjuster plug assembly in the
housing until it seats against the valve body (fig.
58). Remove Seal Protector. Do not adjust the
thrust bearing preload at this time.
4. Install the rack-piston as follows:
a. Lubricate the rack-piston teflon seal with Power
Steering Fluid.
b. Position Seal Compressor J-8947 (Passenger
Cars) J-7576 (Trucks) against the shoulder in
the housing.
