Last weekend I spent a little time putting the motor back together after a good going over, thoroughly cleaning the bearings and repacking them with grease, and finally a coat of paint. I chose red, as the bearings are open and I want to be able to see if grease starts to escape!
I had to make a new motor pivot bolt, so I found an old UN bolt that was too big and turned the shaft down to 14mm for the pivot and 12mm for the hole in the motor mounting place. Finally I turned a M12x1.25 thread and secured the motor in place with a Nylock nut.
Once that was done, I placed the rebuilt pulley assembly (I'm sure I posted pics on this but I cannot find them [EDIT: I found the post HERE.]), along with the brake and the high/low shifter. You may recall from earlier pictures that some clown had busted off the high/low lever and welded a bolt in its place
I turned up a new shaft and two new knobs (I replaced the plastic ball on the brake as well). The brake wouldn't lock into position on its cam and I found out that was because an undersized bolt was used, so there was too much slop. Additionally, the two pins that screw into the pulley assembly and ride in the hi/low selector had been replaced by some ill fitting bolts. I replaced all with some brass screws that I turned up.
Note the thickness of the ring changes, so in one position the screws look too long but just right in the other position. I skimmed the locking collars whilst I had the assembly apart.
Brake lever with brass screw and nut
In place. Note the close fit on the high/low collar
Not the best pic, but the only one I have that shows the "bolt" handle and the cheap plastic ball but it gives you the before and after pics that you all like so much:
