DESCRIPTION

The roller-type hydraulic pump,

driven by the crankshaft, draws auto-

matic transmission fluid down the res-

ervoir and provides fluid pressure for

the system. Steering gear lubrication
is also provided by the same fluid

from the reservoir. Within the pump

itself is a flow-control and pressure-

relief valve which governs the pres-
sures within the steering system ac-

cording to the varying conditions of

operation. After fluid has passed from

the gear, it returns to the reservoir.

REMOVAL AND INSTALLATION

POWER STEERING PUMP

REMOVAL

1.
Open the hood, and install fend-

er covers.

2.
If the vehicle is equipped with air

conditioning, loosen the compressor

adjusting and support bracket bolts

and remove the drive belt.

3.
Loosen the generator adjusting

and support bracket bolts, and remove

the drive belts.

4.
Remove the fan, pulley, and spa-

cer.

5.
Raise the vehicle.

6. Remove the crankshaft damper

bolt and washer. Remove the damper

with Tool 6306-AG. Remove the drive

key.

7.
Disconnect the pump inlet line at

the pump, and plug the end of the line

to prevent the loss of fluid. Disconnect

the pump pressure line at the pump.
8. Remove the pump-to-engine

front cover cap screws, and remove

the pump. Remove the seal from the

front cover.

INSTALLATION

1.
Install a new seal on the engine

front cover.

2.
Align the slot in the pump rotor

shaft with the drive key in the crank-

shaft, and slide the pump onto the

shaft. Install the pump-to-engine front

cover cap screws. Torque the cap

screws to specification.

3.
Connect the pump inlet line and

the pressure line.

4.
Install the damper drive key,

damper, washer and bolt. Torque the

bolt to specification.

5.
Install the fan, pulley, and spa-

cer. Install the generator drive belts.

Adjust the belt tension, and tighten

the adjusting and support bracket

bolts.
6. If the vehicle is equipped with air

conditioning, install the compressor

drive belt. Adjust the belt tension, and

tighten the adjusting and support

bracket bolts.

7.
Run the engine at idle speed,

and check the fluid level in the reser-

voir. If required, add the specified au-

tomatic transmission fluid. Turn on

the windshield wipers. Rotate the

steering wheel from stop to stop sever-

al times to bleed the air from the sys-

tem. Recheck the fluid level.

line (outlet line) at the reservoir, but

do not tighten the clamp.

2.
Attach the reservoir and bracket

to the cylinder block with the upper

cap screw and the lower cap screw

and spacer. Tighten the cap screws.

3.
Tighten the outlet line clamp at

the reservoir. Connect the reservoir

inlet line to the reservoir.

4.
Fill the reservoir with the speci-

fied automatic transmission fluid. Run

the engine, and bleed the system by

cycling the steering gear with the

windshield wipers turned on. Check

for leaks, and recheck the fluid level.
WITH AIR CONDITIONING

1. Raise the front of the vehicle.

Remove the reservoir-to-pump line

(outlet line) clamp at the reservoir,

but do not disconnect the line at this

time.

2.
Disconnect the reservoir inlet line

at the reservoir.

3.
Remove the reservoir bracket to

the cylinder block upper cap screw.

Support the reservoir and remove the

lower cap screw and spacer.

4.
With a drain pan under the res-

ervoir, disconnect the outlet line hose

from the reservoir tube and allow the

fluid to drain.

5.
Remove the reservoir cover re-

taining nut and the cover. Position the

cover and the reservoir out of the way

and allow them to rest in the engine

compartment.

6. Lower the front of the vehicle.

Remove the fan shroud.
