Checking and Adjusting V-Belt Tension
1. Position the machine on a level surface.
2. Lower the bucket and dozer blade to the ground.
Move the joysticks in all directions to verify the

3. Shut off the engine. Remove the ignition key and
take it with you. Lock-out the controls by raising
left control console.
4. Wait for the engine to cool and open the engine
cover and carefully inspect the V-belt (1) for dam-

by your dealer.
5. Press on the center of a span on the V-belt to check
deflection. The belt deflection should be no more
than 5/16” (8 mm). See Figure 4-19.

a. Loosen adjustment bolt (2) and rotate the alter-
nator (3) in the direction of the arrow until
reaching the correct V-belt tension.
b. Tighten adjustment bolt (2) and re-check V-
