losen belt drive sprocket bolts (use brake to hold) the remove belt and sprockets losen rear axle bolts
losen track tentioner bolts all the way use a straps over the tunnel and seat to hold up track while you work
remove susp. bolts slide it forward then pull the rear end out and slide the whole susp. out
remove secondary clutch remove all the nuts holding the driveshaft bearing in place get under sled and push the track up hard against the tunnel off the drivers (help is nice here) then slide the driveshaft toward the clutch side out of the belt case then you can bring it down and out remove track
good time to check bearings and seals (should be fine if its a 15)
change out drivers to 7tooth for the new track (make sur to take carefull measurements to guarantee proper track alignment )
install new track hold tight against the tunnel to get drive shaft in
now reverse what you already did
i think thats it
adjust track to specs and grease all the zerks
i don't know the torques for the belt drive sprocket bolts but the dealer will
good luck
