A gravel like feeling - Snowmobile Forum: Your #1 Snowmobile Forum

Hi guys, I just got my sled back from the shop (1993 Polaris Indy 500) that had engine work done. The guy does good work and my engine is humming now. There's one problem.

When the clutch engages, and I start to move, it feels like I'm rolling over gravel. The feeling --seems-- to be coming from the front of the track, but I'm not certain.

The sled is defrosting in the garage and I haven't gotten into it yet. I figured I'd check for some theories, places to start looking in the morning.

I'm hoping it something like a bogey going bad, but I don't know. I didn't have this before the engine was redone. The engine was pulled, new mounts and everything. So, are there things that can go out of whack when putting the engine back in the sled?

I was thikning that I would start by jacking the sled off the ground so the track is hanging and just pull it by hand to see if I get that same feeling or if it's free.

Any other suggestions?

Thanks!

Mike

You may want to check the track tension. It maybe too tight.

Welcome to the forum!

What you suggest sounds like a good plan. That can rule out the bogey wheels or driveline bearings. I would check the driveline bearings over really well, especially the PTO side.

There isn't a lot of room for slop when it comes to putting the engine back in. Most alignment issues will manifest themselves with excessive belt heat and wear on the belt. But a good mechanic will ensure that belt offset and deflection are set to spec when he re-installs the engine.

Check your drive belt for any burn spots, that will give a jerk feeling Everytime it rotates around the clutches
