ADJUSTMENTS
Front Drive Chain
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 3/8"-1/2" (9-13 mm)
deflection. If the chain needs adjust-
ment, use the following procedure.
1. Remove the chain guard and
loosen the chain guide.
2. Loosen the two eccentric lock-
ing bolts.
3. Loosen the caliper mount bolts.
4. Insert a pin punch through the
sprocket hub and into the eccen-
tric axle housing.
5. Roll the vehicle forward or rear-
ward to adjust chain slack to the
proper dimension.
6. Tighten the caliper mount bolts
to 10-12 ft. lbs. (13.5-16.3 Nm).
7. Tighten the eccentric locking bolts to 60 ft. lbs. (80 Nm).
8. Confirm correct tension by rolling the vehicle forward, checking
chain tension in several places around the chain.
9. Reinstall the chain guard.
NOTE: Reposition the chain guide to allow 1/8" (3 mm) clearance between the
sprocket and guide.
CAUTION
Operating the vehicle with the drive chain slack out of specification could
cause serious damage to the transmission and drive components. Never
operate the vehicle with the drive chain slack out of specification.
