. Rem ove th e flexible coupling pinch b o lt and rem ove the
coupling from th e steering gear stub shaft.
Installation
C A U T IO N : A ll steering gear to fram e, pitm an arm
to pitm an shaft and steering coupling fasteners are
im p ortan t attaching parts in th a t they could affect
the perform ance o f vital components and systems,
and/or could result in major repair expense. They
must be replaced w ith one o f the same part num ber
or w ith an equivalent part if replacement becomes
necessary. Do n ot 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.
1. a. Install th e flexible coupling o n to the steering gear
stub shaft, aligning the flat in the coupling w ith th e
fla t on the shaft. Push th e coupling o n to th e shaft
until the stub sh a ft b o tto m s on th e coupling rein­
forcem ent. Install the p inch b o lt and torq u e to
specifications.
N O T E : The coupling bolt must pass through the
shaft undercut.
b. Place th e steering gear in po sitio n , guiding th e
coupling b o lt in to th e steering shaft flange.
c. Install th e steering gear to fram e b olts an d to rq u e to
specifications.
d. I f flexible coupling alignm ent pin plastic spacers
were used, m ake sure th e y are b o tto m e d on the
pins, tighten th e flange b o lt n u ts to specifications
an d th e n rem ove the plastic spacers (fig. 9).
e. I f flexible coupling alignm ent pin plastic spacers
were n o t used, center th e pins in the slots in the
steering shaft flange an d then install and to rq u e th e
flange b o lt n u ts to specifications.
2. Install the p itm an arm o n to th e p itm an shaft, lining up
th e m arks m ade at rem oval. Install th e p itm an shaft n u t
o r p itm an arm p inch b o lt and to rq u e to specifications.
3. Rem ove th e plugs and caps from th e steering gear and
hoses and connect the hoses to the gear. Tighten th e hose
fittings to specified torque.
POWER STEERING PUMP
Removal (Fig. 33)
1. D isconnect hoses at p u m p . When hoses are disconnected,
secure ends in raised positio n to prevent drainage o f oil.
Cap or tape th e ends o f the hoses to prevent entrance o f
dirt.
D isconnect reservoir hose at p u m p and secure in raised
p osition. Cap hose pum p fittings.
2. Install tw o caps a t p u m p fittings to prevent drainage o f
oil from pum p.
3. Loosen bracket-to-pum p m o u n tin g nuts.
4. Rem ove pum p belt.
5. Rem ove b racket-to-pum p b olts and rem ove pum p from
vehicle.
6
. Rem ove drive pulley attaching n u t.
7. Rem ove pulley from shaft. D o n o t ham m er pulley o ff
shaft as this will damage pum p. Use Tool J-21239-1 for
pulling stam ped pulleys o r Tool J-8433-1 w ith A dapter
J-8433-2 for cast pulleys.
Installation
1. Install pum p pulley.
C A U T IO N : Do not hammer on pump shaft. Use
pulley nut to pull pulley onto shaft.
2. P osition pum p assembly on vehicle and install attaching
parts loosely.
3. C onnect and tighten hose fittings.
4. Fill reservoir. Bleed pum p by turn in g pulley backw ard
(counter-clockw ise as viewed fro m f ro n t) until air b u b ­
bles cease to appear.
5. Install pum p b e lt over pulley.
6
. Tension belt as o u tlin ed u nder “P um p Belt T ension—
A d justm ent” in this section.
7. Bleed as o u tlin ed u nder “ M aintenance an d A djustm ents.”
POWER STEERING HOSES
When servicing pow er steering hoses, avoid tw isting th e
hose unnecessarily. Install hoses w ith th e wheels in th e straight
ahead position, th e n tu rn th e wheels to th e right and le ft,
while observing m ovem ent o f the hoses.
N ote and correct any hose c o n tac t w ith o th e r p arts o f th e
vehicle th a t could cause chafing o r w ear.
A ny m aintenance o peration, on th e pow er steering equip­
m en t, should include a th o ro u g h inspection o f th e hydraulic
line system .
