Seals

Ted in NE-OH · May 26, 2015

I am a fanatic about oil leaks on my restored tractors. Part of the problems is the groove worn in shafts by the old seals over 50+ years. Has anyone taken these shafts and grinding off a few thow and still be in the tolerance for the seals. Is it worth the effort?

Google Speedi Sleeves. They are made by several companies to repair this exact problem.

There are ways to overcome this.There are speedie sleeves which are neophrene tube that just fit over the shaft, then put your seal on and its fixed. I used these on the front crank of an engine block and they work fine, you can also place a seal so it does not run in the groove, shallower or further in, some guys put two seals in place of the old felt IH ones,it can be done.

If you were to actually grind the shafts "down" to the depth of the grooves worn by a seal WHAT would that accomplish? Simply shim the seal a bit outward so the lip runs beside the groove worn over time by the old seal and no $$$$ fixes are needed.

See if you can get a double lip seal in the same shell width as the old one

The speedy sleeves that I have used are plated steel. Most likely you need a few more tractors and other pieces of equipment. They would help you to raise your tolerance for leaks.

A double lip seal is a great suggestion! The seal lip locations are probably shifted from the location of a single lip seal. Occasionally there is enough housing depth to shift a new seal off a wear groove.

Speedi-sleeves are a somewhat pricey, but they are reliable and fairly easy to install. Check the catalog, I think the material is stainless steel.
