In my case, the truck is slipping out of 2nd and 3rd gears going down hill. The teeth are really worn down on those synchros. It has taken some searching for parts. 1973 Ford L8000 with a 3 speed brownie. I love making junk work for me. And I am lucky to have a son that shares my passion for making junk work too.

The syncro is generally a cone and a blocker ring with a friction material on the inside. The teeth on the outer part of the blocker ring are triangular on the front and flush at the back. It’s not usually the teeth that fail, it’s the cone and friction material wearing out so that the pressure from the sliding hub (shift sleeve) doesn’t spin the gear up and the gears are still at different speeds when they engage. This is a decent picture of the type I have seen: https://timstruckcapital.com/blog/what-are-manual-transmission-synchronizers-part-i Bigger views: https://mossmotors.com/synchro-ring-1st-2nd-gear?assoc=20067 and https://mossmotors.com/first-gear-4?assoc=20062 Unfortunately Moss doesn’t have a picture of the sliding hub. There are a variety of different designs so your transmission could be different. I would expect parts would be pretty easy to find.

I am rebuilding a dump truck transmission and don’t to replace any more of the synchros than I need to. It only has trouble in two gears. So goggling “tranny teeth” gave me things that cannot be used in my dump truck. Gotta use the word gear in there somewhere. “Tranny synchro gear teeth”, that works just fine... -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
