Front Drive Chain Adjustment
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.
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″ (.95-.1.3 cm)
deflection. If the chain needs
adjustment, use the following
procedure.
NOTE: See the proper splicelink
clip opening position (1).
1. Remove the chain guard
and loosen the chain guide.
2. Loosen the two eccentric
locking bolts (2).
3. Loosen the caliper mount
bolts.
4. Insert a pin punch (3) through the sprocket hub and into the
eccentric axle housing.
5. Roll the vehicle ahead or back 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 cm) clearance
between the sprocket and guide.
