Strange sound XX4.

[zaquiz]

Hi there,

I know many of u guys over in the UK run the XX4, or had run it in the passed. Here in Spain i am compleatly alone with XX4, but doing quite good since i got back from 15 years abcence in this hobby.

At the last spanish championship a strange sound started in my XX4. Finally the mid-belt broke. I got help from experienced drivers, but none could locate de problem.

It sounds like one of the belts are "jumping" over some tooth. Like someting is vibrating inside of the "belttrain". You can only hear the sound when car is running on the ground. And it gets worse the more thorttle.

When I opened it up, i could see that one of the pulleys were a little damage, but very little. Could it be that?

I am running a 4.5R Novak. Could it be to much motor for beltdriven car?

Hope to hear form you soon.
