Thread: Squeaky squeaky

I know my idler pulley is plastic, ive replaced it. The tensioner puller is metal. Thx for the help all.

I have a problem with the advice of swapping to metal. The plastic pullies do last a very long time, as do the metal ones. The problem area is the bearing. Both bearings from my research are made by the same place and pressed into both pullies. The bearing is the part that goes bad, does it really matter what is wrapped around the part that goes bad?

With metal the belt gets destroyed and fails, with plastic the belt burns through it, gets destroyed and fails. Either way..if a bearing fails.. your in the same place, beltless.

The only advantages I see would be running plastic. Because of the lighter rotating mass. Although I doubt the difference in weight is material to performance.

My advice is use whichever one you choose. And BTW if you look up the pulley thread I posted, there is a metal grooved pulley available.
