So here I am 1 week into trying to change my own belt. Finally got my scoot running again after doing the valves on it. Then 2 days later my belt pops. Got the case of the next day...and well that's where I have been since. I have put a Pneumatic Impact Wrench on the nut at 125lbs...nothing. Then I went and got a 230lb. electric impact wrench. Nothing. I have used breaker a breaker bar. A massive pipe for leverage with the breaker bar....and nothing. I am at a loss here and have no idea how to get this thing off. I don't want to let it conquer me either. I have a Lance Vintage...so the variator is cheap chinese pot metal. (Oh yeah broke a fin off too.) SO it seems to be very weak. Any suggestions on how to get this thing off???

I hear that some versions had a left hand thread- mine didn't. I use my ole trusty Milwaukee electric impact.
One thing you must do is hold the variator with a special tool or I just use a rubber strap wrench to hold the variator. Once you get to where you can hold the variator steady with the strap wrench the impact should take that nut off with minimal effort.
I also recommend properly torquing the nuts back because if you impact it on it will be way too tight. Torque spec for mine is 28 ft lbs.- which isn't much.
Regards

Rubber Strap wrench = Nothing....I also have made my own tool for the variator and still nothing...my impact just keeps slap the nut in the same spot and seems like it will strip it here soon. This is ridiculous....I mean do they use "lock tight" on these things out of the factory?

SO I guess there is a possibility of the nut being cross-threaded on there right now. Does anyone know what would have to be done to remove all of this??? Cut the bolt??? And what would have to be replaced afterwards?

Sometimes a form of Chinese locktite is used and usually the only way to remove the nut is to heat it with a propane torch and then hit it right away with the impact wrench.

Red loctite is the same...need a propane torch to heat up the bolt, then hit it with the impact wrench. No heat = forget getting it off. |

A heat gun works too.

Hit it with the propane! Mine was pretty slammed on there, I noticed right away there was China-style thread locker on there. Mine was also reverse thread. Of the three belts on China-Scooters I have changed, they all had the variator locknuts on way way too tight. When re-tightening, find your correct torque spec, they shouldn't be on very tight at all.

Got it!!!....well not me but it's off. Took it to a shop I was picking a car up at and asked if they would hit it with the big impact gun. Got it right away...Should I also bust off the clutch since the belt shredded itself. Could I have other problems by not looking at it? I am anxious to put it back together right now but figured I would ask since this is my first belt change.
