IMPORTANT: Excessive steering wheel free play may not require
gear
adjustment as covered below. Excessive steering wheel free play
may be
the result of:
1. Ball joints, drag links and/or tie rods loose. If necessary,
tighten.
2. Steering wheel locknut requires tightening. If necessary to
tighten the steering wheel locknut, to remove excessive end
play, be sure to tighten without causing binding.
The tractor is designed with two or more shim washers between the steering gear and
support bracket as illustrated in Figure 20. As the gear teeth wear in, additional steering
wheel free play
may occur. I f the free play becomes excessive, one (more if necessary)
of the shims can be relocated to the bottom side of the steering gear.
Disconnect the drag link from the steering gear. Remove the mounting bolt, lock·
washer and plain washer (shims also if present) from the base of the pivot shaft . Slip the
steering gear and one of the shim washers off the pivot shaft. Place the gear back on the
pivot shaft and secure with the original mounting bolt, lockwasher, plain washer , shim(s)
plus
the shim removed from the upper side. The total number of shim washers must reo
main the same .
A
CAUTION: When adjusting steering wheel free play; make certain
that some free play remains between the sector gear and pinion
gear, since a
tight fit with no clearance between the two gears may
cause binding and tooth failure.
Always
coat all gear teeth with grease each time the two steering fittings are lubricated
or at least each 50 hou rs of operation.
