I have to do a temp. quick fix and replace the leather seal on one side. I looked in the books and can't find the instructions on this one. Does the felt have to go past the lip, do you use just one? Or do you slide the felt in, put the washer in place and press it tight with the sleeve?
I have the felts but don't have time to get the modern seals.

I think the felts, maybe 2 or 3, are jammed inboard of the Hyatt bearing. I bet Chaffin would Fed Ex you the neoprene inner seal.

Does should be "do" :-) Thanks, it'll be felts for now. I have some other parts to order soon and will piggy back a set then.

After looking at my 1921 parts book(s) I don't see a listing for the inner felts. Could be why I don't see instructions for installing felt inner seals in the Service Bulletin's till the newer leather type came out. They are only listed for 1926 and 1927 in the 1928 parts catalog but I guess could be used for earlier cars. After racking my brain I remembered where I saw the info., it's in Murray's book. Not that I would advocate not using seals, but it looks like Ford did not have them till the improved models came out.

In his catalogue Don Lang calls the inner felt seal an accessory, which would explain why it's not listed in the Ford parts book. Look again at the 8-5-28 book and you'll see it's not listed for any year, including 26-27. The 2510B outer felt seal is listed, but no inner felt seal. Ford shows only the leather inner seal (2511/2511B). Don says if you use the felt inner seal, up to three per side are needed in addition to the leather seal, and recommends the neoprene inner seals instead.

The 2511 would be the inner seal. Murray says to place two of the 2510B down by the inner roller bearing and one at the outer bearing end. Reading his info sounds like there was a bigger problem on the left side, which just happens to be the side I am working on. He even goes on to talk abut stuffing rags down the tube to stem the flow, NOT!

I think the accessory felt inner seal mentioned in the catalogue is what I found in my touring rear axle when I replaced the disintegrated babbit thrust washers. It was much bigger than the outer felt seal. I'd post a picture of it if I had one handy. Apparently it and the Fahnestock method were attempts to delay the tendency for the leather inner seals to leak.

That seal sounds like the one that the kits came with more then a few years ago. It's about 4 inches in diam. and has a hole in the middle about 3/8 in diam. He doesn't say anything about using other seals in that paragraph but does go on to talk about other seals in later subjects in the chapter on rear end leaks. Without having a publish date I am guessing it was before Ford started supplying the leather seal because I don't recall them being mentioned.

Anyway, they are in. All three of them on the left side. I will get the neoprene when I put my next order in. The leather was tired after 5+ years of driving and had been leaking, getting progressively worse.

Those heavy inner felt seals are in fact not an original part, but they work very well. The problem with them is installing them. It takes patience, but is well worth it. As far as the original leather seals used in later production, they work fine too. If you have the reproduction spring washer for these, you have to bend every tang on them, so if the leather wears out, it won't machine your axle! The way I do this is to bend all the tangs higher, and test with an axle to make sure they won't cut into the axle.

The one I took out I had cut the tangs back when I installed it. That was the current suggestion I had read at the time. Bending may have been better. Of course with the price of the leather seals...Hum :-)
