POWER STEERING
5-1
GENERAL DESCRIPTION
The steering system used on all 1963 Cadillac
cars consists of a steering gear of the recircu-
lating ball type, power operated by hydraulic
pressure. The pressure is provided by a con-
stant displacement vane type pump, and con-
trolled by a rotary valve concentrically mounted
in the steering gear.
The steering pump reservoir and housing have
been redesigned and some changes have been
made in the component parts. The steering pump
is located on the left front corner of the engine,
Fig. 5-1. It is attached to the engine by a rear
mounting bracket only, and is belt driven by the
engine crankshaft pulley.
The steering gear is mounted on the left frame
side rail and is secured by three mounting screws.
The gear is joined to the steering shaft by a one-
piece flexible coupling, that reduces the trans-
mission of hydraulic valve noises to the car
interior.
The steering linkage, Fig. 5-^2, consists of a
pitman arm, idler arm and bracket, two tie rod
assemblies and a one-piece forged steel drag
link. The pitman arm connects the left side of the
drag link to the steering gear and the idler arm
and bracket assembly connect the right side of
the drag link to the frame. The tie rods serve
as connecting links between the drag link and
steering arms.

Extended life spherical joints are used at the
inner and outer tie rod pivots. There are no pro-
visions for repacking these joints as. they are
packed with grease and sealed at time of assem-
bly. The only maintenance normally required is
to inspect the seals for physical damage each
time the engine oil is changed. At the same time,
the steering linkage joints should be checked for
looseness. In the event a seal should become
damaged or a joint is loose, replace the affected
inner or outer tie rod pivot.
When servicing the steering linkage be careful
not to rotate tie rod ends so that they bottom out,
as the seals could get pinched between stud and
socket and become damaged. If this happens the
entire pivot must be replaced.
