Drive Chain Inspection/Adjustment - 6x6

Never adjust or operate the vehicle with the rear drive chain slack out of the specified range, as severe damage

to the transmission and drive components can result.

Check the amount of chain slack by moving the vehicle slightly forward to gain slack at the top side of the chain.

Then pull up and down on the chain. Total slack should be as specified below. If slack is not within specification,

adjust the chain.

1. Loosen chain guard.

2. Loosen two eccentric locking bolts.

3. Insert a pin punch through the sprocket hub and into the eccen-

tric axle housing.

4. Roll the vehicle ahead or back to adjust chain slack to the proper

dimension. Correct chain slack adjustment is 1 1/4" to 1 1/2"

(30-38 mm) total at the midpoint.

5. Tighten the eccentric locking bolts to 60 ft. lbs.

6. Reinstall chain guard.

NOTE: Reposition chain guide to allow 1/8" (.3 cm) clearance be-

tween sprocket and guide.

To adjust the rear axle drive chain on 6x6 models, loosen the rear most eccentric and rotate using the same meth-

od as outlined for the middle axle chain. Total slack, however, should be adjusted to 1/4"-1/2" (6-13 mm).
