IMPORTANT:
The front idler wheel must now be properly aligned as described below. Misalignment of
the idler wheel will cause the track belt to rub against the side plates. This could degrade track
performance, potentially resulting in the track belt becoming completely jammed and stopping the unit.
3. Idler wheel alignment must be checked next, preferably by using a caliper. Measure the gap
between the forward portion of the idler wheel axle stub and the front end of the idler wheel
mounting slot on each side of the track body. The gaps on both sides must be equal to within 0.5
mm (0.020 in)
4. After the idler wheel has been aligned, re-check the track belt tension by pulling up on the middle
of the belt with your thumb. Correct track belt tension will allow a gap between 9
– 12 mm (0.38 –
0.50 in).
5. Next power up the Minitrac
™ on its side to verify belt tracking, watching for an even gap between
the belt and the two side plates.
6. After the belt is aligned, replace the plastic side covers to prevent dirt and small bits of gravel
from falling between the idler wheel and belt.
