VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1937-1945 1940 Synchronizer Rings

Hi,
should i better replace these Rings? Now the tranny is disassembled anyway. But i can´t get all parts from one dealer

Hi,
i´bought new rings and now i have a problem. It seems that the old one were fixed with 4 little brass bolts - two holes from them you can see in the picture.
Is it necassary to fix the new one too? And when yes, how? I cant drill from the outside because there is the big ring.
Has anyone changed the Synchronizer Rings?

It is necessary to fix the new ones to prevent them from turning.

Hmm,
i thought myself, but it is very difficult with new bolts in the old holes. The new rings have no bolts and where would you drill??
I´ve fixed it now with Loctite 648 - a'High strength/temperature retaining compound'

Think, will work

The new one looks much better than the old ;-)

How are the new rings fastened in place?

Hi,
look on post #270938 - fixed wth Loctide.

In the 41 manual replacing the brass ring (we have been calling it cone) is not a repair option. It calls for replacing the whole synchronizing clutch. Have you been following are discussion under the Mr. Goodwrench - Technical chat site? The subheading Mechanical- engine, trans. etc. has a post called "Transmission removal" with a lot of good info. Sid and I are rebuilding our transmissions.

Good luck, Mike

Now why would they sell a reproduction part by itself if it wasn't possible to use it. I know of other parts in the original Chev manuals that say they are not serviced but replaced and yet we have parts to repair them today.
