IN-VEHICLE ADJUSTMENTS AND REPAIRS

STEERING WORM AND

SECTOR

GEAR ADJUSTMENTS

The ball nut assembly and the sec-

tor gear must be adjusted properly to

maintain minimum steering shaft end

play (a factor of preload adjustment)

and minimum backlash between sector

gear and ball nut. There are only two

possible adjustments within the recir-

culating ball-type steering gear, and

these should be made in the following

order to avoid damage or gear failure.

1.
Disconnect the Pitman arm from

the steering Pitman-to-idler arm rod.

2.
Loosen the nut which locks the

sector adjusting screw (Fig. 3), and

turn the adjusting screw counterclock-

wise.
(On models equipped with the

Cobra Jet engine, it may be necessary

to use a suitable holding tool with an

extension and a long screwdriver to

make the gear adjustment).

3.
Measure the worm bearing pre-

load by attaching an in-lb torque

wrench to the steering wheel nut (Fig.

4).
With the steering wheel off center,

read the pull required to rotate the

input shaft approximately 1 1/2 turns

either side of center. If the torque or

preload is not within specification

(Part 3-1), adjust as explained in the

next step.

necessary. It is suggested that only

those assemblies that are faulty be dis-

assembled. Disassembly and reassem-

bly of the unit and the subassemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost

importance. Therefore, the bench,
tools,
and parts must be kept clean at

all times. Thoroughly clean the exter-

ior of the unit with a suitable solvent

and when necessary, drain as much of

the hydraulic oil as possible. Handle

all parts very carefully to avoid nicks,

burrs,
scratches and dirt, which could

make the parts unfit for use. Do not

clean, wash or soak seals in cleaning

solvent.
