Adjustments
Rear Drive Chain Slack - Concentric Drive Models
Check the amount of chain slack in three different locations by moving
the vehicle slightly forward to gain slack at the top side of the rear
chain. Measure the chain slack at the tightest of the three positions. At
this point the chain should have 3/16″-3/8″ (.48 cm - .95 cm)
deflection. Use the following procedure if adjustment is required.
1. Remove the chain guard if
applicable.
2. Loosen the chain guide.
3. Loosen the two eccentric
locking bolts (1).
4. Loosen the caliper mounting
bracket bolts located under
the axle.
5. Insert a pin punch (2) through the sprocket hub and into the
eccentric housing.
Adjusting or operating the ATV with improper rear drive chain
slack can result in severe damage to the transmission and drive
components. Always make sure the slack is within the stated
specifications.
