David A. Posted February 20, 2013 Report Share Posted February 20, 2013 I need the diameter of the rear axle where the seal rides on a 1/2 ton B2B. I took my axles to a machine shop to have them sleeved where the seals had worn a groove in them. The machine shop has had them so long they don't remember what the dimension was before they turned them down for the sleeve. I don't see how some people can stay in business! Any help will be much appreciated. David A. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted February 20, 2013 Report Share Posted February 20, 2013 surely they turned the unit to a known seal dimension when they did the process..and did not they keep the old part..I know this is not the info you want but I think I would ask them that question to maybe jog their memory or thought process when they first started..was there not a speedi-sleeve available for that application?

David A. Posted February 22, 2013 Author Report Share Posted February 22, 2013 If no one has an axle they can measure, can someone tell me where I might be able to look for that information? Without the OD measurement of where the seal rides, I have two ruined axles! I took them to the machine shop last June. He took forever getting started on them. In the following months he had health issues including a heart attack. He turned them down to accept sleeves he was going to make, but now he can't find where he wrote down the original dimensions. Would the Chrysler product cars of the same era have the same shaft dimensions? If so maybe I could ask on the car side. I sure could use some help on this! Thank You, David A.

Dave72dt Posted February 22, 2013 Report Share Posted February 22, 2013 The problem is someone would probably have to take their axle apart to measure unless someone is in the process of rebuilding. Do you have the seal number? With that number and a seal spec book, you should be able to determine the shaft size that seal was designed for. If the seal number is still good, I may be able to hunt it down for you this weekend. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted February 22, 2013 Report Share Posted February 22, 2013 I walked to the barn with my caliper and measured both left and right axles from a 1950 dodge Coronet..the diameter of the axle at the seal on both was: 1.380 1 Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted February 22, 2013 Report Share Posted February 22, 2013 Now the question is do they use the same axle and /or seal? Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted February 22, 2013 Report Share Posted February 22, 2013 one step at a time...he mentioned asking on the car side for that info..I had these axles out and available to measure..thus the report in case he gets a yes.... another thing the man can do is compare the bearing seating surface on his axle.....on these car axles they mic at 1.375 I do not have a truck manual of any sort here nor any truck parts break down....I am supplying only the information I can verify.. Dave72dt, does you parts house have reference books back to the year of truck in question and can you verify the seal # as stock......once the seal number is known..the physical dimension are always available from companies such as Chicago Rawhide...the application of my axle is 1950 Dodge Coronet, 3.9 rear ratio..11 inch brakes was stock but that is all just backing plate/drum size..you can also look at that seal number and compare to the truck seal..

Merle Coggins Posted February 22, 2013 Report Share Posted February 22, 2013 1/2 and 3/4 ton trucks use the same axle shafts, P/N 11933503 - 32-3/4" long, and the seals used are as follows; Early B1B&C (-82068925 or -83318900) inner seal = P/N 1126007 Late B1B&C (after 82089295 or after 83318900) and B2,3,4B&C inner seal = P/N 1139897 All B-series B&C models outer seal = P/N 1117814 I might have a pair of B2C axles out in my shed, but I haven't had a chance to get out there to measure them yet. If I don't see what you need by tomorrow morning I'll attempt to get back there and check. Merle 1 Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted February 22, 2013 Report Share Posted February 22, 2013 I know there's been some discussion on swapping out truck diff and putting in car diff. If that work's a good chance the axle and housing may be the same.. Maybe on the parts books going back that far. Some seal and brg numbers get taken out of existence, obsoleted and there is no reference for them. Same thing for some manufacturer specific seals and brgs. I'll check.

Dave72dt Posted February 22, 2013 Report Share Posted February 22, 2013 Seal # 1117814 SKF =14359 Shaft =1.438 Bore=2.437 OD=2.441 width =.25 Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted February 22, 2013 Report Share Posted February 22, 2013 From the SKF info the inner seal had 2 different part numbers but they interchange to the same SKF replacement. I bookmarked the SKF site for my future reference. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted February 22, 2013 Report Share Posted February 22, 2013 (edited) Chicago Rawhide (SKF) has always been an excellent resource for seals and as you also see..the speedi-sleeve is already recorded on the data sheet. I really do recommend folks earmarkd this page...I have posted it more than once...their cross reference is great.. as both inner seals, the item in question were today the same common part...I listed the link per each opriginal number so no one would think i made a boo-boo and question the data.. I am just wondering if Dave A. had gone to the SKF site first and found the speedi sleeve woulld it have saved him machine work and staved off this current problem Edited February 22, 2013 by Plymouthy Adams Quote Link to comment Share on other sites More sharing options...

Solution David A. Posted February 23, 2013 Author Solution Report Share Posted February 23, 2013 I want to say thank you to each of you who took the time to research and reply to my question! The information you provided was exactly what I was looking for. After sitting on jack stands for nearly eight months it will sure be great to see it sitting on all fours again. I did do some research on the speedisleeves. My axles had very deep groves and a lot of deep rust pits near where the seals would ride. From what I read it sounded like the speedisleeves were so thin they would tend to conform to any deep groves in the shaft; hence, some recommended filling the grove with epoxy prior to pressing on the sleeve. That in turn made it very difficult to replace the sleeve when it became necessary to do so. After showing my truck a few times, I hope to enjoy driving it a good deal of the time and I just felt a thicker sleeve might save me some trouble down the road. ....I guess I'm paying for all the trouble up front! Thank you all again, David A. Quote Link to comment Share on other sites More sharing options...
