Yes, that is what I meant. I typed that before I found the .pdf.
My idea was to machine a new spacer, I have a lathe. I am guessing the spacer is hardened steel and Aluminum would not be a good replacement.
I can't get my hand in to check the PN103, or see underneath the pulley. I will see if I can scare up a dentist mirror or something similar. It doesn't feel loose.
The PN 102 (the back one) is abit loose, but maybe 1/64; not enough to account for the 1/16 difference. And it is tight once I snipe the other 102. I tried to get a Allen key in there, but there is no room. The only option I could see without taking off the Motor Cover PN52 would be to cut an Allen wrench and then use a socket on it. Also the cooling vanes on the motor are in the way to get to the Allen bolt (102).
At least I know the motor pulley is not pressed on, that makes it a good option to fix this. Thanks for the detailed reply, I appreciate the help.
