Brought my belt blower to dealer

[1nc 2000]

Has your dealer found anything yet with your belt issue?

 

[1nc 2000]

Last year I couldn't get much over 300 miles without snapping a belt in half.
After checking offset and shimming secondary for coil bind I still snapped belts.
My belts would snap on acceleration not at Max speeds.

The fix for mine was replacing the bushing on the moveable sheave on the secondary clutch. My secondary would bind then snap the belt. Over 1400 miles since with no belt issues. Running 8jp belt.

I wonder if “model” makes a difference? I have a 17’ SE (the 129), 1,600 miles, and the belt looks great....just wondering how many guys are blowing them on that model??

Haven't heard anything yet, just dropped it off yesterday.

Of all the things I’ve read posted about the belt blowers this to me seems like a good place to start checking. I know I’ve read other posts of the bushings being damaged but that is the first I have read connecting the issues. While alignment seems plausible also it just seems like too many of the belt blowers measure alignement within spec and we know you have to be careful not damage that bushing.

I saw a prior post from you about your resolution and have been contemplating. The bushing in mine isn't perfect and it makes me wonder. Were your clutches running hot or just cold breaking the belt? How many miles did it take to wear out the bushing or do you think it was like that from the factory?

What causes the damage?

I wonder the same.

My primary was running hotter than the secondary, but I could hold my hand on either clutch.
This year it's getting different weights and springs. I wanted to fix the belt issue before changing clutching components.

Glad you got it fixed. No chance you could keep your hand on either of my clutches, too hot. How many miles were on it when you changed the bushing?

My secondary rollers flat spotted right away and we're changed out at 400 miles and the bushing in the secondary movable sheave was changed out at about 1100-1200 miles.

The 8 dn swap is easy and there are tons of posts here and the viper section it basically takes adding shim washers on the bolts on the back of the secondary sheave or buying an osp belt adjuster that mounts on the helix side of the secondary

The sidewinder roller secondary does not have the 3 bolts on the back of the secondary... Deflection is adjusted by adding or removing shim washers under the large washer on the main bolt.

Just got home from riding my new to me 17 ltx le, it had 900 miles when I bought it and I put on 400 so far. Today I was on a great trail, O’Hara Rd. It was wide open and just let off to get through a corner then wide open again on and off for 2-3 miles. All stock except 144 studs, orange tp secondary spring set to 3-3 and glide washers in the primary. The trail was loose, only showed 105 mph and I weigh 300. The belt is what came on it don’t know how many miles and was sitting a little low in the secondary. When it blew it blew into 100 pieces and got wrapped up in the secondary had to pull the helix trailside to get it out and both clutches were HOT. What do you think should I be worried. Btw smoked my buddy’s 850 xrs renagade but his belt didn’t grenade. And I just got a new belt in the mail yesterday, already washed it and ready to go but didn’t want to break it in today, stupid me.

No. Blew one at 400 and 1800. Exploded so must have been hot. Went with TPI springs and ALL new rollers. Going up to Quebec tomorrow so we'll see.
