obtained by turning the adjusting screw in or
out, as required.
The steering wheel and Pitman arm are
splined to the steering tube and steering gear
shaft, respectively. Both the steering wheel and
the Pitman arm have master serrations to in-
sure correct installation.
The high point is the point of least clearance
between the worm and roller and is at the mid-
point of the worm and roller travel.
An oil seal is installed in the bore of the
steering gear housing at the outer end of the
shaft to prevent oil leakage and to keep foreign
material from entering the steering unit.

Drain lubricant from the steering gear hous-
ing. Mount the gear assembly in a suitable bench
vise, holding the assembly by the housing to
chassis mounting flange, with the steering col-

oil seal housing cover bolts, cover and shims.
Pull steering tube and worm assembly bearing
cups and bearing cages out of the lower end of

Clean the steering gear housing shaft, bear-
ings and other parts thoroughly with a suitable
cleaning solvent. Inspect roller tooth shaft, shaft
serrations, bearings, bearing cups, oil seals,
worm and tube for wear, nicks and flat spots.

6. ASSEMBLY OF STEERING GEAR
(Unit Removed From Car)
NOTE
When the steering gear assembly is disassem-
bled, it is always advisable to install new seals
and gaskets to insure against oil leaks.
If either of the worm thrust tapered roller
bearings have become damaged, it is advisable
to replace both bearings. After thoroughly
cleaning all parts, assemble the parts without
any lubrication. Lubrication should be done
after the adjustments have been completed. If
bushings or needle bearings have been removed,
press new bushings or needle bearings into
place. Use new oil seals.
Insert the worm and tube into the housing
with bearings and cups in the proper order, as
shown in Figure 2. Install the shims and lower
housing cover, making sure that bearings are
seated in cups before tightening screws. Tighten
the cover screws evenly, turning the worm tube
at intervale to be sure no bind occurs. Final
