Rear Hub Seal F60S LAAT
 

Dear friends,

Can anyone kindly tell me where I can purchase 2 x Front and Rear hub seals for my 1944 Ford F60S LAAT.

I have currently removed one hub seal to check my bearings and repack with grease and they both need replacing.

Lorry has been up on axel stands for several years whilst sorting break compents out - slowly going through her.

Any help will be very much appreciated.

Kind regards

Mark

Rear seals are not specific to the F60S LAAT, and were used on a wide range of Ford rear axles (including modern production vehicles!)

Do a Google search for "BB175C", and you will find lots of re-sellers.

Tony means BB-1175-C.

The 4 digit number (1175) in the middle is a base number and if you get the prefix or suffix wrong, you get a different hub seal for some other type of Ford. These seals have a tin extension that drops any leaked oil into a tin shield, which lets that oil run to the back of your brake backing plate, through a hole. It only works as a tell tale if the hole is clear. The bearings are supposed to be grease packed, so that an oil leak means oil has travelled through the outer and inner hub seals from the diff. There is normally an outer seal that stops the diff oil and grease mixing.

Modern part numbers for CMPs
 

Hello Mark,

Please see the thread Modern part numbers for CMPs. Best to start at the last page for the latest updates and/or use the "Search this Thread:" feature.

On a chev truck...yes. But on a Ford there are inner axle seals that are to prevent the oil from travelling to the bearings. You have to split the banjo to get to them.



The chev ones are used on the universal carriers, and can be fitted to the trucks. They are somewhat hard to find. There is a guy on ebay in Australia that sells them for a very reasonable $5 each.

Ford CMP Rear hub seal- BB 1175 /Timken 5751
 

Hi Mark,

A Google search came up with a Timken number from another Ford forum and the attached link which may help.

I haven't got one handy to check measurements but photo of it looks the same as the BB 1175. Timken numbers are often used as the industry standard.

Cheers,

I always had it as a National 5751, but there has been so much takeover in the seals and bearings manufacturers in the past while, I can't keep up with it anymore.



Here is a link to the outer wheel seals for those who use them.

Rob, for a trip down memory lane there is a thread:
MLU FORUM > MILITARY VEHICLES > The Carrier Forum. Rear axle seals.
FORD Timken axles as found in a carrier or civvy axles do not have seals in the axle tubes and do not have a machined surface on the half shaft for a seal to run on. There is also no specific stepped area inside of the rivets that a seal might sit against. (I have a carrier diff in pieces at the moment) I assume the F60S LAAT is the same??? (other than the ratio)
There are obviously two types of outer seals (leather and metal- see the other thread) and it seems that in some applications there was never an outer seal fitted. I don't know of a variation that has tube seals, but I am a learner.

On my KL, which I did back in the 90s, I opened the axles to replace the inner seals. If I recall correctly, on the front axle you need to separate the axle in order to do the long side....the short side could be done from the outside. It was a PITA, and theoretically you would need the correct thickness gasket as that sets the backlash for the differential.



I just checked a 3 ton manual sitting behind me, and group 4702 is for those seals.....4 used on the Ford split type axle and located right next to the differential bearings.
The UCs for some reason did not use that method and instead used the GM seal in between the adjusting nuts for the wheel bearing.

Thank you all for your help , useful links and support, your advise is very much appreciated.

I will endeavour to order the seals over the weekend and hope to have my lorry rolling by the end of the summer.

I will report back soon.

Kind regards

Mark

Rob, I see now that you are referring to the front axle, while I was talking about the rear.
Mark, check out your options. They should be found at lower prices than Jacques's listing?

Nope, rear as well.

Ford CMP- Front hub seals
 

Hi Mark,

The front hub seals you require I assume are the attached?
Pocket in hub for seal is shown with seal removed and the seal.

Imperial measurements of the sample should be enough for any bearing or seal supplier to match up. As a check you can measure the ID of the pocket, the OD of the steering end which it seals upon, and the depth of the pocket.

I downloaded the CR Seals catalogue and it is a wealth of info on seals.

Yes, the quote for the rear seals were outrageous but I only put it up to show the seal and the Timken/National number. You should be able to do a better price.

Rear seal BB 1175 C is a generic Ford part number for 1934 to 1948 large trucks so is available at a few vintage Ford parts suppliers.
F-15A Parts List refers to it as BB 1175 C also, so it is not unique to CMP vehicles which makes obtaining them easier.

Cheers,

They are from the US, so you need to factor in shipping, but when combined with other purchases, they work out quite economical ( :thup: for EarlyFord2OK on Ebay, some good parts there, and their shipping is always overquoted, works out cheaper in the end.)

Rob. Interestingly The British manual (Chilwell 63/63. Jan.43) shows seals at all 3 locations. The tube seal is shown in a rebate as you say.
I have 3 axles made in the USA (1940) for the N.Z. govmint to go in the 40 Bren carriers built here in N.Z. (they don't have the rebate or the seals) These would have been Truck axles for use (I assume?)with the enclosed prop shaft. These 1938 pattern axles have the weld on mounts for the two arms that go forward to the prop shaft housing and have crown wheels that bolt to the diff carrier.
Back to topic.
