STEERING GEAR (Fig. 1)
A three-tooth roller is mounted on needle roller
bearings on a steel cross shaft inserted through
the steering gear shaft.
The worm is integral with the steering tube
and is supported at each end by tapered roller
bearings. The worm bearing pre-load is ad-
justed by means of shims placed between hous-
ing and housing end cover. The steering gear
shaft rotates in two bronze bushings pressed
into the steering gear housing. The three-tooth
roller on shaft is meshed with worm. When the
steering wheel is turned, the worm rotates the
steering gear shaft and roller, moving the
steering gear arm, which is splined to end of
shaft and held in place with a nut.
Backlash between steering gear shaft roller
tooth and worm is controlled by an adjusting
screw that is threaded through shaft and roller
cover. The base end of adjusting screw is en-
gaged in a slot in end of the steering gear
shaft. Correct backlash can be obtained by
turning adjusting screw in or out, as required.
The steering wheel and arm are splined to
the steering tube and steering gear shaft, re-
spectively. Both steering wheel and steering
gear arm have master serrations to insure cor-
rect installation.
The high point is the point of least clearance
between the worm and roller and is at mid-
point of worm and roller travel.
An oil seal is installed in bore of steering
gear housing at outer end of shaft to prevent
oil leakage and to keep foreign material from
entering the steering unit.
