Do the 944s come with both a 5 and a 6 rib alternator pulley? When my brother went to buy a belt for his 944 the parts dude gave him the wrong 6 rib belt, makes me think they were both used.

I'm asking because I'm in the middle of a supercharger install on my 928, and I need a 6 rib pulley for the alternator. I'm hoping (wondering if?) a 6 rib 944 alternator pulley is available that will fit on my 928 alternator. Anyone know the diameter of the alternator shaft on a 944? The 928 shaft is 0.669" diameter.

Here I go again, answering my own questions.

And the answer is (drum roll.....) Yes. The later 944s come with a 6 rib pulley. The 944 alternator shaft is the same diameter as the 928 alternator shaft. The 944 pulley is slightly larger (maybe 0.10") in diameter.

 

Gee, you're handy to have around
