VCCA Home Forums Thread Like Summary - 1941 3 speed gearbox

Hi all,

I’m rebuilding a customer’s gearbox, and I need to find a set of synchronizer cones, as well as a second gear. In a perfect world, I’d be looking for a third gear, or clutch gear as well. Also, the service manual says something about “energizing springs” and slipping them off over the clutch teeth. I assume they’re referring to something in the 2nd/3rd gear clutch on the mainshaft, but I’m not seeing anything in this gearbox like that, and there’s no picture of them anywhere. I didn’t see them in the exploded diagram in the Chevs of the forties catalog, either.

Any help?

Thanks,
Reid.

If anybody would like to help a brother out, and tell me what the energizing springs are, and where I can find them (or where they’re supposed to be) I’d appreciate it. I like doing things right the first time. If something’s missing in here, I’d like to source it before the unit gets installed, fails, and I have to warranty my work. Again, there’s no reference to them in either the factory service manual diagrams, or the chevs of the forties exploded diagrams.

I am going to try and post a link of an online GM manual. It is the 38 Chev shop manual but it shows the operation of the synchronizer and the energizing springs. Although the transmission is a little different I think the synchronizing is very similar.
