Hey i just fixed my squeeling. I roughed up all the pulleys with emery cloth and a file. I then replaced the bolt that had a cog like washer i guess? on it.. it was supposed to pull the ALT. up a toothed track to tighten the belt...
I just got a normal bolt. Pulled up as hard as i could on the ALT and then tightened the bolt down. Been 500km and hasn't squeeked a peep!
