hope someone can help me here....my Fb is an 82 which is equipped with A/C. I recently replaced that motor with what seems to be an SA 12A. I know there are slight differences between the Sa 12a and the FB 12a but one thing i have not seen that i am running into is the main pulley that the A/C pulley connects too. I was switching all my 82 parts to this replacement engine but i am having difficulties mounting the A/C pulley to the SA main eshaft pulley. There seems to be a notch sticking out of that pulley and it is not letting me mount my 82 AC pulley on to that pulley because of that notch. I am NOW trying to take off that pulley but that notch seem to be keeping that main eshaft pulley in place....i have never seen this before. I don't want to break anything. Anyway i can remove this main pully or the notch holding the pulley? Hope this is clear.....thanks in advance for any help

 

82 pulley i am trying to put on




the pulley on the engine currently that is not coming off. The notch is circled in the pic. i dont want to bend it and break something....any one have any input before i go breaking stuff lol? at first i thought it was a screw but it was a notched rounded head (not for any screwdriver)

 

just grind it or replace the entire assembly. thats the disadvantage of pre-81 motors but on the positive side, you will always find TDC since there is only one way to install it. LOL

 

It's just a soft aluminum rivit. If you look at it funny it will shear off. Can you find a cold chissle in hot Texas summer?

 

^thanks for the info guys.......
