propeller shaft seals

[Tom_Tams]

Can anyone give me the part numbers for the propeller shaft seals for a '39 series 40. I have the group # which is 5.469 but I don't yet have a copy of the 1928-1941 chassis parts list. Any assistance in this regard would be greatly appreciated.

Apparently, the GM PN's are 1308321 & 1308322. I've tried to reference those numbers and come up empty. Has anyone replaced those seals, if so, what seals were used?

Here's the sizes too. Try making enquiries with the sizes and not part numbers. I just walked into the local bearing supplier here in Sydney and asked for modern T-type oil seals. Had them the next day.

Without the group number was unsure what seal you were after

As Danny, comment, walk into a industrial bearing suppler:- not a car parts shop. Will also be a a lot cheaper

Thanks, I'll give that a try and thank you for the sizes, that should help

Hi Danny, I tried using the sizes you gave me, didn't matter, he used his calipers and surprise, surprise he could find no matches. This was an industrial bearing supplier. I guess maybe the work ethic is a little stronger where you are or the reference data is. Thanks anyway, it should have worked.

I read this topic and  found that some have found a replacement seal by going to a bearing supplier and replacing seals by size.   I tried to do this online, in trying to do so, I learned the OD of seal 130831, listed in my parts book and depicted above in danhar's post, is incorrect.   The OD is listed as 29/32", it should be listed as 1 29/32".  I didn't dig my seals out of storage, I just went off the dimensions in my parts book.  Which are the same dimensions depicted above for seal 1308321.  

With the OD listed as 29/32" (and my lack of knowledge how number of parts needed are depicted in the parts book) it lead me to assume the listed ID of 1  17/32"  didn't mean "one inch and 17/32" it  meant "one part needed with a 17/32" ID".   

I just dug my seal out of my stash, and my measurements are consistent with  1 17/32" ID 1 29/32" OD x 1/4".   Hopefully, this information may save others some time and frustration.  If anyone knows the part number of suitable seals, please post them or PM me.  I am not looking for NOS, I am trying to find new seals with new rubber, in leu  of NOS with rubber that is up to 80 years old.

The part numbers are:130821 and 130822.  They are not the same as one is front and one is rear.  I could not find these seals in 1968 anywhere, so good luck on that.  I have one front seal and several rear seals left.  Some are rubber in metal and some are leather in metal.  That is hare on all I have.  Soon, I intend to replace the differential and it will come with the rear torque tube.  I'm not planning to trust that old used front bearing and seals.  In 1968 I found several in a junkyard building in Laurel, MD.  Good luck on that now.  I've bought every one I've seen on eBay over the years.  I don't know if soaking the seals in oil will soften the leather and/or rubber or not.  That works on cork.  I have collected a number of Hyatt bearings for the front of the rear axle.  I couldn't get that in a bearing house in Baltimore in 1968, so, again I've bought every one I ever found on eBay.  I still have several.  I've restored my car plus a three other 1939's I've had over the years and have now sold.  I could sell a bearing or two, but no seals I don't think.  At least not until I finish this current job.  IF ANY OF YOU FIND modern, fresh seals that will satisfactorilly replacce 130821 and/or 130822, please let me know.

[buick looks fine for 39]

I don't know how well they work but Bob's Automobilia had modern replacements in their catalog 4 or 5 years ago. I bought a set but I didn't throw a caliper on them and I haven't tried to install them 

 

Thanks Leif
