Summit Weird Belt Wear Pattern

[tmurphy]

This is off a 2011 Summit X 800 163. The wear pattern is on the outside of the belt. Anybody ever see this wear pattern before? If so, what was the cause? Its not from parking brake being left on. I noticed it on my belt, i installed a new one and it wore exactly the same.

looks like perhaps your belt is too tight, it only rubs there at idle

may have clutch alignment problem wearing on one side like that.... belt should wear evenly across the belt when properly aligned. and also, does look like it's too tight.........

X3 and not aligned see how it's not worn even across.

 

[tmurphy]

The belt sits about 1/8" above the secondary. Is that too tight?

 

[Summitric]

nope, but you might get the clutch alignment checked... best to use clutch alignment tool

 

[Summitric]

is that wear on the inside or the outside of the belt?

 

[tmurphy]

Outside.

Recent oopsy on the pass side? Look for damage that would be involved in the engine being twisted.

he would be pulling cords if it was an alignment issue, when you are sitting still there is an offset because your primary moveable sheave is on the outside and all the way open and to the left. the secondary moveable sheave is the inside sheave and all the way closed. as the sheaves move together the belt straightens up into the middle of the primary taking out the dogleg that exists when at idle. that's my theory anyways.

if the marks are on the outside of the belt it is rubbing on the hood or cover or belly pan. nothing to do with deflection or alignment.

look at the pic? the rub marks are on the underside of the belt that contacts the primary at idle....

Tee rosy nobody wants your opinion.........

 

[maxwell]

are you having belt life issues? if not let her buck. like teeroy says there is a designed offset to straighten out when on the throttle

Belt is too tight. When mine did that it was very difficult to get into reverse. Loosed your secondary a little bit.

Are you running at top speed quite a-bit??( like on a hard pack surface)
In the bottom of the secondary there is a lip that can cause this .
With really low gearing that these have it could be that.

 

[tmurphy]

Definitely not.

Not really. I've only blown one belt and that was because i was in 3' of fresh last year in Chappel and just couldn't stop playing, Self inflicted failure. lol
