WHEEL ADJUSTMENT
The caster (forward slant of the king pin) and the cam­
ber (tilt of the wheels out at the top) require no adjust­
ment. Automotive steering principles have been used
to determine the caster and camber on the tractor. The
front wheels should toe-in 1/8 inch.
Some units have adjustable tie rods so the toe-in can
be adjusted. To adjust the toe-in on these units, follow
these steps.
1. Remove the hex nut and lock washer, and drop
the end of the tie rod from the axle bracket. See
figure 22.
2. Loosen the hex jam nut on tie rod.
3. Adjust the tie rod assembly for correct toe-in.
