STEERING
'
€ight Cylinder Models:
(1) From under the vehicle position the gear on
the crossmember and install the three gear housing
mounting bolts. Tighten the bolts to 55 foot-pounds,
on AV2 and AR2 models, and 80 foot-pounds on
AP2 models.
(2) On AV2 models lower the engine on the front
engine mount pads and install the front engine mount
stud nuts and washers. Tighten the nuts to 75 foot-
pounds.
(3) Install the starting motor.
(4)
Position the steering gear in center of high spot
(worm master spline should be at 12 o'clock) and in-
stall the steering gear arm, washer and nut. Tighten
nut to 120 foot-pounds.
(5) Connect the hydraulic hoses to the steering
valve.
(6) Position the clamp on the steering shaft cou-
pling and with the master splines on the wormshaft
and notch on the body of the coupling aligned, en-
gage the column coupling with the steering gear
wormshaf t.
(7)
Install the coupling ring bolt and tighten the
bolt to 200 inch-pounds.
(8) Position the steering jacket assembly
so the
steering shaft coupling is centered at the midpoint of
up and down travel.
NOTE: On ARl and A V l Models
a
"Ils
gauge hole
i s provided in the steering column shaft, when the
dimension from the top of the coupling to the cen-
terline of the gauge hole is
inch, the copuling is
centered in its travel. On
AV2
models with manual
transmission and power steering measure
"Ils
inch
between the top of the coupling and the bottom of
the dust seal. On
AP2 models when the bottom edge
of the gauge hole is tangent to the top edge of the
seal the coupling is centered in its travel.
(9)
With the coupling centered, tighten the column
jacket to the instrument panel clamp bolts to
95
inch-
pounds.
(10)
Connect the battery ground cable.
(11)
Start the engine, turn the steering wheel to
right and left several times
to expel the air from
the system.
(12) Inspect the power steering pump reservoir lev-
el, replenish as necessary.
STEERING VALVE RECONDITIONING
(1) Remove the two screws attaching the control
valve body to the steering valve body and separate
the two bodies (Fig. 21).
(2) Compress the control valve spring and remove
the retainer pin, spring, valve piston and cushion
spring.
(3)
Carefully shake out the spool valve and inspect
the valve for nicks, burrs and scores. Do not re-
move the valve body end plug unless inspection indi-
cates a leak at the gasket.
NOTE: If
the
spool
valve or valve body i s damaged,
replace the valve and body assembly.
Small burrs and nicks may be removed with crocus
cloth if extreme care is used not to round off the
sharp edge portion of the valve. The sharp edge por-
tion is vitally important to the operation of this
valve.
(4)
Clean the valve bodies and valve pistons thor-
oughly in clean solvent. Blow out all passages and
blow parts dry with compressed air. Lubricate pis-
tons and bores with Power Steering Fluid, Part Num-
ber 2084329.
(5) Install the steering spool valve into the valve
body so that the valve lever hole is aligned with the
lever opening in the valve body. Valve must be per-
fectly free in the valve body without sticking or bind-
ing (Fig. 21).
(6) Install a new gasket on the end plug (if re-
moved). Tighten the plug to
25
foot-pounds.
(7)
Install the piston cushion spring in the control
valve body being sure it seats in the counterbore
at the bottom of the housing. Lubricate the piston and
insert the nose end of piston into the body bore.
Test for smooth operation. Be sure the cushion spring
is not cocked.
(8) Install the spring on top of the piston, com-
press the spring and install the retaining pin.
(9) Position the two new
"0" rings on the control
valve body and attach the control valve body to the
steering valve body. Tighten the two attaching screws
to 95 inch-pounds.
(10) If the pressure inlet fitting has been removed,
tighten the fitting to 30 foot-pounds.
GEAR SHAFT OIL SEAL REPLACEMENT
The gear shaft oil seal may be replaced without re-
