Rear Drive Chain Slack - Polaris Trail Boss 2007 Owner's Manual

MAINTENANCE AND LUBRICATION

Rear Drive Chain Slack

CAUTION
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.
Check the amount of chain slack in three different locations by moving
the vehicle slightly forward. 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
bolt located on the left side
of the swing arm.
5. Insert a pin punch (2) through the sprocket hub and into the
eccentric housing.
