Ijust bought a 94 formula stx for my first sled and don't know much about sleds. I was cleaning and greasing it up and when i was finish i fired it up. Even at idle RPMS it seemed to be moving a little. The front skis were on dollies and the track was just on the cement. Sould the sled move a little at idle?? If it was on snow I dont think it would move at all.

what rpm was it idling? The dolles could relive enough friction to let the sled creep a little.

Check the belt height on the secondary, and the belt deflection. Sound like the belt is too tight. You'll have to check the shop manual for the correct specs.

But since you had the skis on dollies, this could be a normal condition.

The belt my just be too tight. On my sled if i jack the back end up in the air the track will start to move. The belts jus too tight. :D

well it does it around 1,000-1,300 rpm range. The garage floor is really smooth and i have really good dollies. It just move a little every couple of seconds when at idle. If the skis were not on dollies it would not move at all I don't think.

If that's the case, it's probably normal. Of course, it doesn't hurt to do a clutch alignment anyways. It should be done every season.

sounds normal to me. Your track should slowly move at idle on any sled if its up in the air.

After you run it like that for five or so minutes, touch the drive clutch hub. Caution! You'll burn your fingers because belt friction got the the hub scorching hot. This heat then goes to your seal and bearings. The belt is too tight if your track turns at such a slow ilde. If the track is in the air when your idling it's not so bad but if it's on the ground there is no give anymore.
