Front Drive Chain Adjustment
Check the amount of chain
slack by moving the vehicle
slightly forward to gain slack at
the top side of the front chain.
Then pull up and down on the
chain. At this point the chain
should have 3/16″-3/8″ (.48 cm
- .95 cm) deflection. If the
chain needs adjustment, use the
following procedure.
Adjustment Procedure
1. Loosen chain guide.
2. Loosen two eccentric locking
bolts.
3. Loosen caliper mount bolts.
4. Insert a pin punch through the
sprocket hub and into the ec-
centric axle housing.
5. Roll the vehicle ahead or back
to adjust chain slack to the
proper dimension.
6. Tighten caliper mount bolts 10-12 ft. lbs. (1.4 - 1.7 kg/m).
7. T ighten the eccentric locking bolts to 45 ft. lbs. (6.2 kg/m).
8. Confirm correct tension by rolling the 6x6 forward, checking chain
tension in several places around the chain.
9. R einstall chain guard.
NOTE: Reposition chain guide to allow 1/8″ (.3 cm) clearance
between sprocket an d guide.
