My 1918 replacement transmission brake drum only has one bushing in it. Okay, no big deal...I'll just replace both...until I compared it to another drum with both bushings. The bushing inside the drum has a shoulder, or flange (thrust surface) and I can't find that particular style with the vendors. Snyder's bushing picture shows a straight, cylindrical bushing and only mentions that you need two.
Should that inside bushing have the thrust? Oh, I'm ordering the MTFCA book on transmissions tomorrow!
The information will be in the transmission book, when replacing the old style bushing you use different thrust washers, the bushing no longer are sold and have not been for many years, with the thrust flange as part of the back one.
Here is the information from Lang's catalog;
Thank you for the information Mark.....looks like I have two different vintage drums! I'll review Lang's site and order the book tomorrow.
