'97 Ski-doo Clutch Recall

'97 Ski-doo Clutch Recall

Post by Richard Har » Sat, 16 Jan 1999 04:00:00


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
like me.

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,

 
 
 

'97 Ski-doo Clutch Recall

I don't know where your dealer got his information, but the clutch recall
had nothing
to do with the angle of the clutch faces.

The fixed half had too short of splines on the shaft, it could also develop
cracks
due to poor castings.

The outer half could develop cracks due to poor castings.

Ski-Doo was concerned that some of the clutches might explode if this
problem wasn't addressed.

I have experienced some cases where replacing the clutch halfs has cured
belt
burning and glazing, but the only reason is that the new clutch fixed a
misalignement
in the pulleys.

You can also get the clutches to run cooler by removing the windage trays
off of the driven pulley.
This is a must for high altitude riding, otherwise the pulleys and belt will
overheat.
