I've torn down the entire unit, cleaned and inspected parts. Replaced and updated worm gear. After rebuilding the unit locks up in 3rd gear. 1st & 2nd gear works fine. Went through the assembly again taking everything apart and inspecting it. Couldn't see anything out of the ordinary so I reassembled, but again as soon as I install the hub and shift it into 3rd it locks up?
Jeff your almost there....it must be the shifter into third....it must not slide fully into third....check for wear marks on the worm gear....and try running it without the protective cover on to see how it changes from 1st, into 2nd, then third...that mechanisim if not engaging totally in third.
Qwert, thanks for the response. I've been at it all day building, tearing down, etc. I need to amend my original post and mention that it binds in 3rd and in 2nd. No amount of adjusting the center shaft corrects the concern either. Six ways to Sunday I know I have every part in the unit installed correctly.
The original concern with the unit was a busted worm gear shaft "old style" and badly worn worm gear which I've attributed to the broken shaft.
I'll check the shifter again, and let you know.
It definitely has something to do with the shifter, but i don't know what. If I fully engage it into 3rd it binds, the same with 2nd, but ifI back it off from the #2 or #3 shift position no more binding. I know it's still in the desired gear 2nd or 3rd at least I think it is. Why would it start doing this after performing a rebuild?
Qwert, I purchased a new worm wheel assembly from Treasue Coast because the old one the shaft was broken. I can tell now that when 3rd is engaged the worm wheel assembly pushes the transmission gear assembly away and this is when the binding is occurs after the clutch and transmission cover is installed. Is it not possible to install an updated worm wheel assembly in an older unit? If it is possible does one have to install a new transmission gear assembly at the same time as well so they are a matched set?

Loosen the two planetary nuts, should be a thin nut and an acorn nut. With these loose make sure the large nut on top of the transmission is tight. Push the planetary all the way up on the shaft and turn the thin nut up until snug. Back the thin nut off 1/4 turn. Hold the thin nut in position and lock the acorn nut against it. The planetary must have a very small amount of up and down play.
