My '97 Ski-doo GT-SE 700(bought new in '98) has always 'glazed' drive
belts in a very short time?
Studying the several belts I had used, it was apparent that my clutch
was only contacting the bottom of the belt teeth and thus glazing the
rest of the belt sides because the belt would slip and heat-up. This
resulted in engine over-reving and very pour power transfer. I had to
change a belt after about ever 10hours because it was 'glazed' and no
longer worked properly.
I confronted my dealer with this, and "reluctantly" he admitted that
Bombardier had made an error in the angle of the '97 clutch contact
surfaces!!! He said "There is a factory recall on these clutches, but
"Officially" I am only supposed to change the clutch with the new
one(with the new contact surface angles) when the old one cracks". I
asked him, "Why would the old one crack?" He said "That since the belt
slips heat builds up and the casting will crack in time." So he goes
into his parts room and pulls out a new clutch kit. I take a look back
there and he has a stack of dozens of them just waiting for customers
He changed the clutch contact plates under warranty and it works great
now. As a bonus, by scuffing up the the sides of my old 'glazed' drive
belts with a file, they now work great. I now have enough drive belts to
last a very long time.
Good luck and fun sledding,
