IMPORTANT:
Tractor must be on the ground during alignment procedure. Any adjustment made while tractor is on stands will be incorrect.
Allow tracks to cool before beginning checking alignment.
Checking Alignment
1.
Make sure both inner and outer adjusting screws (B) are tight on each track frame.
2.
Drive tractor in a straight line on a flat firm surface for about 400 m (1300 ft).
NOTE:
Make sure track is correctly aligned by checking temperature on both inner and outer guide lug (A) surfaces approximately 25 mm (1 in.) below belt carcass. If actual temperature is measured, the inner and outer guide lug surface measurements should be within 5° C (41° F). If the back of hand is used to check temperature, there should be no distinguishable difference.
If temperature difference is detected, see Adjusting Alignment.
3.
Check both inner and outer guide lug surfaces.

Adjusting Alignment
NOTE:
Tightening inner adjusting screw (B) moves track toward tractor chassis and tightening outer screw moves track away from chassis.
Do not adjust screws by more than 1/2 turn at a time. Retighten lock nuts before driving tractor.
1.
If guide lug outer surface is hotter than inner surface, loosen both lock nuts and outer adjusting screw, then tighten inner adjusting screw and lock nuts.
If guide lug inner surface is hotter than outer surface, loosen inner lock nut and adjusting screw, then tighten outer adjusting screw and lock nuts.
2.
Drive tractor in a straight line on a flat firm surface for about 400 m (1300 ft).
3.
Recheck alignment and repeat Step 1 above until temperatures on each side of guide lugs for both tracks feel about the same.
