My Belt problem

[Machinegunner]

I have the same vibration that everyone else has at the various speeds. What I have noticed and finally located the source is very pronounced roaring when under full acceleration in high gear when in the 55-60mph range. I finally found that noise is from the belt rubbing on the lower belt guard in front of the rear sprocket. My belt is tight enough to play a tune on it. The gap between the belt and the guard is about 3/4 of an inch. I can't for the life of me figure how it could possibly rub when it is so close to the sprocket. If it was rubbing near the center of the belt I would understand the flexing. Any ideas??? I don't think it is serious problem, but it could get worse later on. I can't see how belt could flex that much.

RUBBING

Hi, IMHO your belt is way to tight........Mine ( RT ) is less than spec by quite a bit.....( 185 lb on ground w/ Kritkit )... I have no vibes ......and I'm not the only one who has discovered this ODD occurrence. ......................Mike :thumbup:

Mike, I knew I could depend on you, but what is causing it to hit the belt guard if it is too tight????

Once the belt gets to dancing around under the spell of "Harmonic Vibrations": all bets are off! :shocked:
There have been some videos shot of the effect (Finless posted one), and it's pretty startling!
