I've disassembled the fan and pulley from my 1100794 alternator to send them out to get plated and have a couple of questions which hopefully someone can help me with:
1.) Both the fan and pulley have a slot in them which one would assume would be used with a woodruff key yet the shaft on the alternator does not has a slot for a key. I'm fairly certain that both are original to the alternator and car since the pulley does have the "7" stamped on it and the build date of the alternator (A25) is in line with the build date of my car (01D). Why would they have a slot in them if the alternator shaft does not have a key way?
2.) Are the pulley and the fan attached with a nut and lockwasher or a nut and a flat washer?
