GENERAL INFORMATION
The power steering gear (Fig. 1) should NOT be
serviced or adjusted. If a malfunction or oil leak
occurs. The complete steering gear should be
replaced. If a steering gear boot needs to be replaced due to
damage, refer to the power steering gear service sec-
tion in this manual for proper procedure. The power steering system consists of these four
major components. Power Steering Gear, Power Steer-
ing Pump, Pressure Hose, and Return Line. Turning of
the steering wheel is converted into linear travel
through the meshing of the helical pinion teeth with
the rack teeth. Power assist steering is provided by an
open center, rotary type control valve which directs oil
from the pump to either side of the integral rack piston. Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn. The torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This movement
directs oil behind the integral rack piston, which, in
turn, builds up hydraulic pressure and assists in the
turning effort. The drive tangs on the pinion of the power steering
pump mate loosely with a stub shaft. This is to permit
manual steering control to be maintained if the drive
belt on the power steering pump should break. How-
ever, under these conditions, steering effort will be
increased.
STEERING GEAR SERVICE
The power steering gear should NOT be ser-
viced or adjusted. If a malfunction or oil leak
occurs. The complete steering gear should be
