replacement alternator pulley?

Just a thought, but check the planar alignment of the various pulleys.

If they are not sufficiently in the same radial plane and the belt has to flex from one plane to the other, squealing will result. This can sometimes be compensated for by LOOSENING the belt.

Several years ago I worked at a place that had extreme dust conditions and alternator pulleys would frequently wear out. We got ours through NAPA and the alternators and replacement pulleys were "Wilson" branded. Your NAPA store may or may not get this brand, however and the parts guy will probably have to look a little harder than normal to get these pulleys. Once again, it all depends on the store. You can do a "Wilson alternator" search on google and it should come up. These were top quality replacement pulleys that looked stock, came in all sizes, groove numbers and diameters.

That is a GM alternator right? The wreckers should have lots. The rebuild kit I have for it covers AMC, Buick, Cadillac, Chevy, Chevy/GMC trucks, Jeep, Olds, Pontiac and various farm vehicles.

Figures, I don't know of a NAPA nearby, however I do have a good local FLAPS I will ask if they carry that line. thanks for the tip.

Alternately, I just got a catalog of Ford truck restoration parts and they offer what appears to be a stock-style chromed fan and single grooved pulley. Anyone know if the shaft is the same size/shape between a Ford alternator and a Delco alternator?

I actually have a spare 63 amp Delco in my garage, but it has a double groove pulley on it (came off a Cadillac) Don't have a local junkyard to score another one from.

Why not just use the double groove pulley if the belt align and the diameter is close?

Because that would not be aesthetically pleasing with the hood open. Yes, this is one of *those* kind of cars... don't get me wrong, I'm building it to be a driver, but I want it to look presentable under the hood as well.

summitracing.com search for alternator pulleys.

I have the $20 underdrive one on my race car. They have all sorts of billet and shiny ones for show purposes. :)

Or, you could find one at a junkyard and clean it and paint it...

I've looked there, and all I could find were 'billet' ones which doesn't really fit my theme... for example, the air cleaner is off a '62 Vette (louvered chrome steel) and the valve covers are repros of the old Offenhauser finned aluminum ones. Basically I am not using anything that couldn't have been found in the 50's or 60's with the exception of the alternator itself. (my one concession to driveability.)

HOWEVER... since I went back and looked, one pulley/fan kit was listed as "for Delco or Ford alternators" so I am assuming that the Ford one that looks like what I want will work. So it wasn't a totally fruitless search!

If you can use a stock one, a decent parts place should let you swap yours for a good used one, at NO charge, for a core/trade-in. Done many parts this way, altho' I've always had to do the labor swapping!!! HTH, s
