A Study Of Seals

[Hanno Spoelstra]

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.

Using the link above, this one cross references to SKF 45150:

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]

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.

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]

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

[Lynn Eades]

Ian, fyi a neoprene seal can replace a leather one.
Measure the bore
Measure the shaft it runs on.
Measure the width of the gap in can fit in.
google "skf 45150" and check the dimensions shown against your numbers.
Go to your seal supplier with the number.
spend the money.
