  • Cork seals

    We're working on a 1946 Oliver 80 Standard tractor and need seals for the crankshaft (front & rear) and the governor shaft. These are all made from cork, 2 are 1/4" thick, one is 3/8" thick. Does anyone have a source for cork sheet in those thicknesses, where I don't have to buy a huge quantity? We figure we can turn the equivilant of arch punches to make them.

    Alternatively, would these be availble pre-made? Sizes are 3" X 2 3/8" X 3/8", 2 1/4" X 1 1/2" X 1/4", and 3 3/8" X 2 3/4" X 1/4".

    TIA: <<Jim>>

    McMaster Carr has cork sheets in various thicknesses. Rubber blended sheets are kind of expensive but plain cork not too bad.

    Give Zatkoff a try, they are on Airport Highway.

      Using the measurements you have shown, you should be able to convert over to neoprene seals. National puts out a book with every seal size they make. The newer neoprene seals do not leak like the old cork seals did. JIM

        You might try a flooring specialist and buy a single cork floor tile.

          Newer lip seals could be made to work, but with a bit of effort. I'm kinda figuring that if those old seals didn't leak back then, they won't be too bad now. The tractor won't probably see 100 hours of use in the next 20 years.

          Will look into those other sources, thanks!!

          Would the rubber blended stuff be better than plain cork?

            Jim, do you think you could make them up out of 1/8" thick material? Easier to cut than 1/4 or 3/8. Maybe glue them together with something like non aerosol Hi-Tack, making sure to keep the red stickum away from the rubbing surface?
