Title: Sloper felt seals
Post by: Oval57 on 24 Oct, 2024, 06:20
Hi
Does anyone know where I can get a set of felt seals for a 1930 S30-13 deluxe ? If not has anyone got a picture of the seal that fits on the engine shaft inside the timing cover
Thanks
Roger

I don't know if this will be of much use, but the felt seal 24-715 is shown on page 45 of the 1930 Parts Book.
I don't know of a supplier of these, but I think they are quite hard felt, and are cone shaped on one side to fit into the timing cover bush. You could work out the OD and ID by measuring the bush and quill. Maybe you could fit the timing cover with some plasticine to check the thickness?
However, for the last 30 years, I have been using Scholl Felt Corn Pads. They are about 7/8" OD. Unfortunately, since then, Scholl have redesigned them and they are now made of foam. But if you search the internet, you should be able to find some Felt corn pads. They are quite soft and a bit thin, so I use two, and have never had a problem.
Otherwise, you could simply cut one out of felt sheet. You will find the felt will easily take the shape of the bush.

Cheers Steve, good idea with the plasticine, I was thinking of just making one out of some industrial felt that i have, (we used to make seals out of this years ago ) hopefully it will work
