[QUOTE="Jad G, post: 11527446, member: 14624"] [b]Metco Alternator Pulley too far Forward, causing belt misalignment[/b] Ive been having belt squealing issues after slinging a belt off. I put on a metco 3.5" OD alternator pulley with separate spacer bushing to match the speed of the 6# caged lower and the lower idler came off while driving and slung the belt loose but in the process rubbed on the rib of my new caged lower, which is of course custom made and not easily replaced as well as the alternator rib. Now I think the new alternator pulley is spaced farther away from the case than the stock one and that misalignment is making the ribs in the belt angled slightly, but enough to cause increased noise and premature wear, in combination with whatever damage to the belt the damaged rib is causing, and unfortunately I lost my stock alternator pulley in the process. :bash: EDIT: I have acquired another stock alternator pulley to measure against the metco, which i did at work using a granite block and caliper and found the metco pulley to be 40 thousandths too far forward. [ATTACH=full]289451[/ATTACH] [ATTACH=full]289452[/ATTACH] The stock pulley is on the left This is after machining the spacer down 40 thou: [ATTACH=full]289453[/ATTACH] I had to grind a bit off the aluminum ring around the shaft to make sure it didnt run against the now closer back face of the pulley, but it was very little and i easily did it with my dremel. I edited this post to show what I found purely for the knowledge of others on here. [/QUOTE]
