Gen4 Summit X 850

[mecham]

So I noticed that with very little pressure that the belt hits the front roll of the tunnel by the back of the secondary. Mine has done it enough to rub the paint off the tunnel. Hard to tell in the pictures but its actually hitting the tunnel not the black piece with all the holes in it by the footwell. Anyone else notice this or can check their 850's and see if this is happening on more than just mine.

maybe this is where some of that belt dust is coming from?

Is your belt adjusted to the right tention?

Looks ok, going by that 3rd photo.

Yes belt is adjusted correctly, I knew someone would ask that's why I uploaded that last picture.

I just looked at mine and it's not rubbing the tunnel in that area, but there's a rivet right there that looks a little shiny.

With one finger with light pressure can you make yours rub? Because if you start it up with the guard off you can see how much those belts move around.

If you can get your finger in to push it back that far it is not adjusted correctly by a long shot.

Feel free to explain to me "how to adjust it to properly", it's sits where it should at the top of the secondary. Am I missing something else when adjusting it?

Yes you are missing something--all the manufacturers give you a belt deflection measurement. It is irrelevant where it sits in the clutch your deflection is what matters.
Here is how I do it the easy way -- put the sled on a stand or suspend the back end somehow so you can run the sled.
Cycle the belt a few times by winding up the sled from a full stop to close to shift out to warm up the belt and the clutches. (or take it for a ride to get it all warmed up)
Now cycle the clutch through once and let the track stop by itself so the clutches shift back completely. Shut of the sled and loosen the secondary (nut) and unscrew it 1/2 turn--turn the secondary until the belt starts to tighten up. About 1 Revolution.
At that point I lightly tighten the nutted and run the sled again. I do that until the belt slightly creeps the clutch forward at idle .Shut here down and tighten the secondary nut usually about 1/8 to 1/4 turn tighten jam screw up and you are good to go. Now you will for sure start your ride in 1 Gear and not put undo wear and heat into your belt by always starting in second gear. Your rubbing will be a thing of the past.
After you have done this a few times you will know exactly what deflection your belt should have to work properly. If it squeals at idle you are slightly to tight. Hope that helps.

No but I can make it touch.
