rrunnertexas Posted January 13 Report Posted January 13 I pulled the steering box out of my 1935 Plymouth PJ since it felt just a touch loose and the bottom seal was leaking. With it all apart I'm ready to put it back together and found that the replacement bottom seal is too large to fit in the Gemmer box itself and there is a gap around the seal where in contacts the shaft. So, that tells me that the 1935 seal must be smaller than the 1936 and up seals. See attached photo. Left seal is new and too large, right is slightly mangled original. My hope is that someone out there has the correct seal or knows where I can get one. I'm stuck until then. Quote

keithb7 Posted January 13 Report Posted January 13 (edited) My Motors Manual tells me 1935-39 Plymouths used the same Gemmer gearbox. My Hollander Exchange book says otherwise. Gemmer part number 640505 upto SN 2446145. After sn 2446145 Gemmer part number 645332. Not very helpful when I do a google search. That old info seems long gone. I do know that the 1935 to 1942 Fords also used Gemmer steering gear boxes. The vintage Ford parts market is infinitely larger than the Mopar market. Try these guys here. https://www.millworkshotrod.com/products/january-v92-x14 and here: https://www.earlyfordstore.com/products/1935-1948-steering-sector-seal Ask them for the seal internal diameter. Keep digging up Ford steering parts. You'll find one. This is how I bought all the parts I needed to rebuild my 1938 Plymouth steering gearbox. I got them all from the Early Ford Store and they fit great. Edited January 13 by keithb7 1 Quote
Sniper Posted January 13 Report Posted January 13 (edited) A good bearing supply house should be able to rustle up the correct seal based on your dimensions. Are there and identifying marks on the old seal? https://www.skfextranet.com/crsealsfinder/ looks like 10515 is close https://www.skfextranet.com/crsealsfinder/datasheet.aspx?s=10515 Edited January 13 by Sniper Quote
rrunnertexas Posted January 13 Author Report Posted January 13 Keith, So, it sounds like the gear box in this '35 PJ is early and smaller in size. Too bad all the good info on parts is hard to find now. Sniper, I was checking and hoping, but no numbers or identifying marks. Bearing supply house - hummmm... Quote
rrunnertexas Posted January 13 Author Report Posted January 13 Keith, I sent an email to both of the links you provided. Perhaps in a few days I will find paydirt! Fingers crossed. Thanks for the help! Quote
