Posted: Tue Apr 22, 2014 9:47 pm Post subject: Prime and Rust
I have a '52 M38A1. I have removed the transmission and transfer case. It does not have a emergency brake drum. Is this normal? It does have an OD. It was added afterward (I'm assuming). Was this normal? Also, I took the transmission cover off. After cleaning it completely and primed it I have a "silly" question. Does one paint the inside of the cover and the inside of the transmission? Also, can or do you put silicon in between the tranny and its cover ( and on the transfer case before bolting it back on) before putting the gasket in or just the gasket? I know oil leaks are a part of the project but I'd really rather not have any leaks at all.
Last: Everything seems to start turning orange. Is there something I can put on the parts (including bolts, washes etc) to prevent this until I am ready to put everything back together again?
I moved your post to our technical board where we answer technical questions.
1-The M38A1 is notorious for a rattling parking brake linkage and shoes. The only fix is to replace the rattling parts with new or rebush them to make them snug again. Hence a lot of A1's have had their parking brake linkages and drums removed.
2-Overdrives are often added to increase highway cruising speeds and make the jeep quieter at those higher speeds.
3-If you must use sealants with gaskets then use Permatex #1 or similar sealants, not silicon/rubber RTV's. 99% of gaskets were made to do all the sealing on their own. Folks usually resort to sealants on gaskets when they tend to leak because the mating surfaces are damaged or they want to hold the gasket still during installation. As a general rule if the assembly instructions do not direct the use of a sealant along with the gasket then don't use any. If the purpose is to hold the gasket still then put the sealant on the side of the gasket that is removable (IE cover). This makes the old gasket and sealant easier to remove from the cover over on the work bench when you reopen it later.
4-The orange or oxidation of bare metal is a common problem when bare metal parts are left out for some time. You can spray them with a oil base protectorant. You can store them in zip-loc bags. You can send them out and have them cadmium plated. _________________ Wes K
