The pulleys are still available new from Cummins. Chances are the alternator shaft is chewed up and shot due to a loose pulley which ate up the keyway. There is a vendor that has decent prices on them but the name escapes me right this minute. I'm sure someone will chime in.

I ordered a new pulley off of Ebay and it was an India manufactured one also. It only had one keyway though. On my original pulley, someone had assembled it wrong and cross threaded the nut on the shaft. I cleaned up the threads and assembled it correctly without any issues. Can you post some pictures of your friends pulley with 2 keyways?
