Just a note. The transmission on my 1953 locked up today. I thought maybe it was a bearing. As I was disassembling it, I noticed that the fixed sheave, which it heated to put on and off, had moved out and locked up against the tensioner bracket! On the very early transmissions, there is no other mechanical means of attachment. I guess that is why they machined a groove on the later ones for a snap ring! I just heated mine and tapped it back to the proper position. I then let it cool and added Loc-tite Green, which is made for penetrating already installed fasteners. We shall see if it holds. If not, I guess I will have to have a groove machined on mine.
