'68 L35 1100794 Alternator

(1/1)

Camarocards:
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?

Thanks,

Bob

Marty:
The pulleys and fans I've seen all have slots. I have 3 1100794 alternators and all 3 look like they have a thick flat washer. I don't see a split in it.

Camarocards:
Thanks for your reply Martin. Seems odd that they have the slots with no key way in the shaft. Maybe they were also used in other alternators that had provisions for a woodruff key?
