OD: 4.569"/ 116,05 mm
ID: 3"/ 76,24 mm

Part number: BB-1175-C
Part name: Retainer - rear wheel grease (leather oil seal)

I bought these locally as new rubbers seals for EUR 25,- each.

Mac's Antique Auto Parts list them as follows:
Part# | Price | Description | Additional | Year

Seal "no.5":

NOS leather seal.

Measurements:
OD: 6.25"/ 159,8 mm
ID: 4.5"/ 120 mm

Part number: *C01Q-1190-B
Part name: Seal - front axle hub grease leather oil seal

I bought these locally as NOS leather seals for EUR 10,- each.

EDITED TO CORRECT: this is not Part number *C01Q-1190-B as that cross references to SKF/ CR 49998 with ID 5" and OD 6.25"

In cv joint Bob posted a picture of this seal, with I presume a modern part number written on the piece of paper.

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.

Thanks Lynn. I should have listed known applications.

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:

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.

Not sure if you're quoting the right number?
SKF 49998 has sizes Shaft 5" and Bore 6.25": http://www.skfextranet.com/catalogs/...il.asp?s=49998

Will verify with the supplier on Tuesday....... could they be overlooking the 1/4 inch rubber skirt on the inside...?

Will keep you posted.

Bob Carriere · #11 11-10-18, 23:42

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??????

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.

Bob Carriere · #14 03-08-19, 05:46

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

I have only just come across this thread. At present rebuilding an axle for a Carrier, after researching a replacement seal for the hubs, I found that by searching with the Ford part number, BB1175C, I came up with one manufactured by Chicago Rawhide, now marketed under SKF name. It is a modern type of hub seal that turns within itself and thus doing away with the old type lip to seal path idea. Found a SKF data sheet for said seal, and it listed all the Ford and other makers part numbers that the SKF seal no. 31307 covered, inc. BB1175C. I knew the shaft size was correct, having measured the axle, 3.125", but having seen the Ford part number as well, neglected to check the OD assuming it would be OK. On receiving these seals from a dealer in the US, I now realise the OD is incorrect, the data sheet shows OD of seal is 4.631", where as the hub bore actually measures 4.560" (which is what Hanno quotes in his post here). There is also a discrepancy in the width of the seal as well, but that is not as important as the OD.

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?

Lynn Eades · #16 03-06-11, 02:16

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
