First you might want to invest in a spell checker. Secondly, try using punctuations and grammar, might help people understand you better even though it wasn't hard to understand.

On topic. Check if the pulleys are not warped or bent or if one of the pulleys are out of alignment.

Hope that helps.

phong =P~

You may also want to check the bearings in the pulleys.
