A. Front Wheel Replacement
Do not disassemble the castle nuts when you replace the front wheels.
It is only necessary to tighten the nuts so that the wheel turns freely on the axle with minimum end
play . (See Fig. 13) Tighten the nuts after replacing the wheels.
B. Rear Wheel Replacement
Do not disassemble the castle nuts when you replace the front wheels.
It is only necessary to tighten the nuts so that the wheel turns freely on the axle with minimum end
play. (See Fig. 14) Tighten the nuts and put on the cotter Pin after replacing the wheels.
C. Front Wheel Alignment
a.
The front wheels should be "toe-in" from 1/8" to 1/4" . To check for
alignment, measure distance A and B between the centerline (CL)
of the wheels. The proper toe- in dimension A should be 1/8" -1/4"
greater than dimension B.
b. To adjust the alignments, loose the lock nuts on both sides of
Front Tie Rods. To make Dimension B smaller, scare the rod to the
left. Adjust the rod to right direction to make Dimension B larger. After
adjusted to desired length, tighten the lock nut against the rod end.
Recheck the dimensions for proper alignment.
