meadowbrook Posted February 12, 2017 Report Posted February 12, 2017 Hello folks. My 50 Dodge's 's driveshaft located parking brake drum is also the sealing surface for the trans rear seal. THe sealing surface is a bit pitted with corrosion where the seal rides. Do you folks think I could fix that with a light dabbing of jb weld to fill in the pits ? Either that or a new drum, which seems unavailable. Quote
Dodgeb4ya Posted February 12, 2017 Report Posted February 12, 2017 Install a "Speedi-Sleeve" on the drum hub ....It's been talked about here many time before.... 2 Quote
etzmolch Posted February 12, 2017 Report Posted February 12, 2017 Did it last week on the diff. hub. The best you can do, as Dodgeb4ya said and dead easy. They recommend to use some kind of metal filler and then install the sleve, if the grooves are to deep, Quote
dpollo Posted February 12, 2017 Report Posted February 12, 2017 Good advice. permanent repair because of the hardness of the Speedi sleeve. Quote
meadowbrook Posted February 12, 2017 Author Report Posted February 12, 2017 I'll see if I can find this, I hope it does not overstretch the new seal. I got a NOS leather one. Quote
etzmolch Posted February 12, 2017 Report Posted February 12, 2017 (edited) The speedi-sleeve is exactly for this purpose. Wall-thicknes is 0.28mm ~ .011" of the SKF ones. Oil seals usually can handle this. I see you said you get a nos leather one but se no reason why it should not work with those too if do the same procedure as described in the shop manual for new leather oil seals.

plyroadking Posted February 12, 2017 Report Posted February 12, 2017 Or you can also press the driveshaft bolts out, swap output flanges, and reuse your existing brake drum. R9 overdrives have different output flanges, and you'll have to turn it down a little to fit into the od transmission brake drum. Quote
classiccarjack Posted February 15, 2017 Report Posted February 15, 2017 Don't forget to presoak your leather seal in oil before installation. I had to reseal the back of my transmission twice because of not taking this step. I used grease on the first seal. If anyone else knows of a less messy way, I am all ears. I soak them for a day with the same oil that I am using in the transmission. Then wipe them clean and install. 1 Quote

meadowbrook Posted February 15, 2017 Author Report Posted February 15, 2017 Thanks all, got a speedy sleeve from Amazon on 1 day, worked like a charm. We'll see if it still leaks. I'm a fan. They are razor sharp though, careful. 1 Quote
JBNeal Posted February 15, 2017 Report Posted February 15, 2017 On leather seal prep, I have had good luck with a variation on what i read in a shop manual: I soak the leather in 10w30 at room temperature for a day, then take a clean and smooth deep socket to massage the leather in a circular pattern for a minute in both directions, then soak another day in the oil that the seal will be retaining. I prefer neoprene but sometimes that is not an option on an old beast 2 Quote
