rageracing 16 Posted December 23, 2020 Share Posted December 23, 2020 Got a leak here at the back. Any torque specs for the bolts? Also do I need to pull the driveshaft and take the big nut off to pull it apart? If memory serves me you don’t but been years since having it apart. thanks! Link to post Share on other sites
broker-len 140 Posted December 23, 2020 Share Posted December 23, 2020 it probably is leaking from seal----you have to pull the front of the driveshaft off then the brake drum there should be a seal look at your owner's manual Link to post Share on other sites
broker-len 140 Posted December 24, 2020 Share Posted December 24, 2020 to answer your question YES the cotter pin and nut has to come off when I replaced my seal on a 32 Plymouth PA did not have to take brake band off Link to post Share on other sites
keiser31 5,851 Posted December 24, 2020 Share Posted December 24, 2020 (edited) I took mine all apart to get to the seal in my 1931 Dodge DH6 transmission. Your seal may be the same as mine.... Edited December 24, 2020 by keiser31 (see edit history) Link to post Share on other sites
rageracing 16 Posted December 25, 2020 Author Share Posted December 25, 2020 Thanks guys! I’ll give this a stab soon. I always had an oil leak from where the speedometer gear comes in, any idea about that? Tried an o-ring once to no avail. Link to post Share on other sites
rageracing 16 Posted December 25, 2020 Author Share Posted December 25, 2020 There is no front seal on these trans too I believe. Should I put a little rtv on the front nose that bolts on? Link to post Share on other sites
1932 plymouth pb sedan 33 Posted December 25, 2020 Share Posted December 25, 2020 Before installing tail section you should remove speedometer gear, can be done without removing but don't risk bending speedo drive gear. Don't ask me how I know. (sometimes I do learn from my mistakes) Link to post Share on other sites

rageracing 16 Posted December 28, 2020 Author Share Posted December 28, 2020 Well pulled the nut and took the bolts out and now I have this and it won’t slide back together. Suggestions please Link to post Share on other sites
keithb7 1,309 Posted December 28, 2020 Share Posted December 28, 2020 (edited) I think you went in too far. You are now removing the rear tranny brake support housing. You'll now need a new gasket for in there too. To access just the rear seal, the park brake drum is removed, slid off the tranny output shaft. It can be a stubborn bugger. A puller may be needed. Then you can see the rear seal that is pressed into the brake support housing. To fix up what you've done, you will need to remove the park brake linkage and drum. Remove speedometer drive gear. Then hopefully remove the brake housing. Sliding it toward the rear. I can't recall 100%, but the main shaft of the tranny and main rear bearing may be pressed into the brake support housing. I hope not. If so, the the entire main shaft of the tranny comes out with the rear brake support housing. Then the gasket can be accessed. When it was out on the floor I removed the rear seal and install a new one. Acquire a new paper gasket to re-seal the brake housing to the rear of the tranny. Hopefully this all can be done with the tranny still in the car. I am doubtful. If the entire main shaft has to come out...... I have only done this work with the tranny out on the floor. See my pic here. This was my '38 tranny. You can see the entire main shaft of the tranny is still pressed into the brake housing. Shown here, I am installing a new rear tranny seal. Hammering it in place with a tube. One more for reference. Again, these are all pics of my 38 tranny. Yours may be slightly different.

rageracing 16 Posted January 8 Author Share Posted January 8 Cleaned up where the seal rides. It had grooves worn in it. Took it down to 1.5” so trying a 2.562 ODx1.5 ID by 1/2” thick seal 1 Link to post Share on other sites
