A Study Of Seals
No, this is not Sir David Attenborough's latest documentary on marine mammals
Recently I took stock of the grease seals I have for my CMP. Some came with my F15A when bought, others were acquired later. In this thread I will post known details, but also ask the members to add information if they can supply it. I have five different seals, numbered 1 - 5 in the picture below. Thanks in advance, Hanno

No4, BB-1175-C is the inner hub seal for the Ford 3 ton axle. This seal fits the various carriers (bren and universal etc) and probably most of the trucks of that era. Tony Smith will give you a more accurate application list.

So BB-1175-C fits the F15A, Universal Carriers as you say, and indeed most other CMP trucks. It cross references to Chevrolet Part No. GM-1798517. Dirk Leegwater has them posted on his site, which is where I bought them from: Quote:

So, my question is, does anyone know if there is another SKF number for this seal, to suit the actual size required for the axle, and has anyone else had this problem?

Your no.1 seal, if it is correct for the F15, is probably the one that goes inside your axle housings to keep the oil in the diff and knuckle ends. The housing is usually dry between.
C01Q 1190B crosses over to gm 1809797

Just a guess but this looks like the transfer case power take off seal.

Seal 5
Yep, this is the one you need to replace when you see grease and oil coming out of the brake drums. Amazingly they seem to last about 60 years.

Chicago Rawhide and National who are the two largest USA seal suppliers put out several cross over books
One from OEM part numbers to theirs. Another cross references from size to manufacturers numbers. Also Cr produce another publication on sizing for speedy sleeves which have to be one of the greatest inventions since the war. What is not commonly known that if the shaft is out of limits for roundness, the sppedy sleeve will bulge up and make the shaft unusable. When I worked for Kenworth we did not bother with micrometers if the sleeve went on OK then you could be sure it would not leak. regards Col

Cross Reference and Dimensional Information On Line
Cross Reference and Dimensional Information On Line I have been using Motion Industries for a number of years to purchase seals and bearings for my CMPs they have a very usable on line sited http://www.motionindustries.com/moti...mii/index.html which I have found almost every seal and bearing that I have needed. Most of the seal numbers or bearing numbers found on Chevy CMP parts are still good numbers. The Motion Industries site also gives you the dimensional and detail information on the parts. One word of caution be sure to look at all of the cross over possibilities as there is a huge price range for “interchangeable” parts example wheel bearing depending on the precision and speed range have a huge cost.
Even if you don’t use Motion Industries the listing gives you a number of different manufactures for the same parts. Cheers Phil 3August2019 - just checked and the link to Motion Industries is still good

Bearings and seals experience.
When I was purchasing bearings and seals I use a small dirm in Ottawa that had a web search engine that allowed them to look up parts by dimensions. As long has I had the proper precise metric ID....OD..... thickness.....application.... they were able to find modern replacements.
I did the axles, tranny and T case. At the barn we had 3 instances were the proper bearing could not be found.... ..... the flat bearing for the front axle egg cup.... New departure 928....... did find a few old stock but at fantastic prices..... but Dirk has ome NOS. The bottom bearing for the rear of the tranny was impossible to find.... but found some good used ones from our stock of spare transmissions. On the HUP front axle there is an inner oil seal..... that keeps the differential oil from moving to the eggcup...... we could not find the proper ID / OD combination...... we opted for the proper ID size and had a local machine shop make an adapter from aluminium that matched available OD dimensions. Installed easily and was pegged in place with a centre punch. Bob

Seals
I am just rebuilding my F15A and refitted the front axle. I have replaced all the oil seals with modern lip seals. I do not trust NOS. I just took the old ones in, and sometimes I even took the housing in ( except for the inner seals). I replaced the wheel bearings and cones at great expense. I have a list of part numbers somewhere.
The best service in Australia is Eastern Bearings in Melbourne.

Correction...Hanno is right....
The seals they brought in was the wrong size.
DO NOT USE 49998...... 499 stands for 4.99 inches inside diameter... PROPER PART NUMBER IS 45150..... WHICH MEANS 4.51 inches inside dia. ....and of course they had them in stock and the price is $60.35 CDN plus taxes which comes out to $136.39 for two. Plus shipping to where ever?????? Cheers

I am getting confused,
I have a C8A over here, with seals outer dia. 6.25" and inner 5.00" are they a different size then the C15A?? In the manual there are 2 sizes of joints, 5" or 6". with 4 or 6 studs at the steeringlink. But no 4,5" ???? I can not find them. Groeten Hendrik

Is the old seal in the C8A the following dimensions: Shaft 5" and Bore 6.25"? If so, then use SKF 49998 http://www.skfextranet.com/catalogs/...il.asp?s=49998 If it measures Shaft 4.5" and Bore 6.25", then use SKF 45150: http://www.skfextranet.com/catalogs/...il.asp?s=45150 You can cross reference any seal via http://www2.chicago-rawhide.com/ > "Seals North America Part Lookup". Punching in Shaft and Bore diameters gives you a list of current seals. HTH, Hanno

Partial Information
Great,
A part number.... but which manufacturer??? In Australia this isn't enough to identify a seal correctly. Cheers, Ian

The part numbers are Chicago Rawhide (CR) which is also SKF. However, it is more likely you want part number 45150, not 49998.

Correction......
The 45150 number provided by Hanno and Rob ARE the correct numbers.......also fits C15a and HUP front axle available from SKF.
