Correct Alternator Pulley

[cjkeeliii]

Does anyone know where I can get the correct diameter pulley for my m1008's alternator? I have an extra alternator, but with a smaller diameter pulley than my ohter alts. I've searched the net fruitlessly. Does diameter of pulley matter? Thanks.

Well I have found the PN 1978068 in -34P but its not popping up with an NSN so that is rather odd. Will look further into it. I have found all the specs for one on a m1010 but not the others.

give me the diameter that you need, and a picture, I might have one of them

If you have the dimensions you should be able to get the pulley from a "real" auto parts store, or, try a local alternator/starter rebuilder. The width of the grove is important also.

Get a shorter belt. The alt I got from autozone for the drivers side had a smaller pulley and I just got a slightly shorter belt and it works fine.

Belt, Alternator, Drivers Side:

DAYCO Part # 15570 will be 1 inch shorter than the 15580.

I think the Gates # is just 5570.

Man I have to stop this. It's like a treasure hunt...................

GM 1978068

Looks like it is going to be a 77mm pulley and the closest NAPA has is this one.

It is 3 1/16" x 3/8" belt.

Maybe you already know and have checked this, it is not only the length of belt that's important, it's also the correct width of belt versus pulley width for which it's designed. If your belt is "slipping" or "squealing", look how the belt is laying in the "V" groove. I believe it should ride maybe a 1/32" to 1/16" above top of pulley. If it's riding way down below top edges of pulley, then you either have wrong belt or pulley or the belt is worn so bad that it ain't even funny. Just something else to look at when talking belts/pulleys. Smokey
