Ski-Doo REV series 2007 Operator's Manual page 218

To Adjust Track Alignment:
Remove tether cord cap before performing any maintenance
or adjustment, unless otherwise specified. Vehicle must be
parked in a safe place, away from the trail.
– Remove the tether cord cap.
– Loosen rear idler wheel retaining screws.
– Loosen the lock nuts (on so equipped models).
– Tighten the adjustment screw on side where the slider shoe is
the farthest from the track insert guides.
1. Guides
2. Slider shoes
3. Tighten on this side
Tighten lock nuts (some models only) and retaining screws.
If lock nuts are not tightened properly, the adjusting screws
could loosen causing the track to become extremely loose and,
under some operating conditions, allow the idler wheels to
climb over the track lugs forcing the track against the tun-
nel causing the track to "lock". Properly tighten wheel retain-
ing screws, otherwise wheel may come off and cause track to
"lock".
