6C-2 POWER STEERING GEAR
POWER RACK AND PINION
The power steering rack and pinion system has a rotary
control valve that directs hydraulic fluid coming from
the hydraulic pump to one side or the other side of the
rack piston. The integral rack piston is attached to the
rack. The rack piston converts hydraulic pressure to a
linear force that moves the rack left or right. That force
is then transmitted through the tie rods to the steering
knuckles, which turn the wheels.
DESCRIPTION AND OPERATION
If power rack and pinion steering is not available, manu-
al rack and pinion control is used; however, with this
system, more steering effort is required. The movement
of the steering wheel is transferred to the pinion. The
rotary movement of the pinion is then transferred
through the pinion threads, which mesh with teeth on
the rack, thereby causing the rack to move in a linear
direction.
A vane-type of hydraulic pump provides hydraulic pres-
sure for both steering systems.

PINION GEAR BENCH TESTING
Removal and Installation Procedure
Notice: Pressure checks or pressure and flow checks
may also be conducted using this setup.
1. Disconnect and remove the power steering gear.
Refer to “Rack and Pinion Assembly” in this
section.
2. Place the power steering gear on a bench next to
the vehicle.
3. Disconnect the pressure line at the point where the
hose connects to the pipe. Extend this line to reach
the power steering gear on the bench.
4. Disconnect the return line from the power steering
fluid reservoir. Extend this line to reach the power
steering gear on the bench.
5. Connect the power steering pipes to the power
steering gear.
6. Start the engine and allow it to idle for 10 seconds.
7. Check the power steering fluid level. Refer to
Section 6A, Power Steering System.
8. Start the engine and turn the rack and pinion stub
shaft a full turn in each direction. Hold the shaft
against each stop for 5 seconds.
9. Inspect for possible leak points. Refer to Section
6A, Power Steering System.
Installation Procedure
1. Stop the engine.
2. Disconnect the power steering pipes from the power
steering gear.

3. Remove the extensions and reconnect the pressure
and return lines.
4. Install and connect the power steering gear. Refer
to “Rack and Pinion Assembly” in this section.
5. Start the engine and allow it to idle for 10 seconds.
6. Check the power steering fluid level. Refer to
Section 6A, Power Steering System.
STRAIGHT-AHEAD CHECK
After all the necessary operations on the steering gear
are completed (removing and installing, disassembling
and assembling), check the exact straight-ahead posi-
tion of the steering in each case.
With the vehicle on the floor, place the steering wheel
in the straight-ahead position. Mark the centerline of
both tires on the floor. Turn the steering wheel all the
way to the right and mark the new centerline of both
tires on the floor.
