A little background first. There are two types of Oil Seal Rings, one is Solid
and the other is Scarf Cut. Solid is obvious, but the Scarf Cut needs a picture
like the one below to explain.
Trying to stretch these solid teflon seal rings is no easy task. They feel very
hard to the touch. First I tried steaming hot water for 10 minutes and I thought
that was helping. But now I'm not so sure. I also tried just considerable constant
pressure, after maybe 20-30 seconds they would begin to stretch enough that
you could slide them over the shaft and install them in their ring land. When I
say considerable pressure I mean more than you can do with your fingers, you
will need something the right diameter to help you push on the seal. So it's got
to be big enough to slide over the shaft, but small enough that it contacts the
seal ring.
Now the seal rings are much too big and need to be re-sized to make them smaller. I'm not real happy with my process, there must be a better way. But it did work so I'm happy it's done.
BTW, all 5 seal rings are the same size. Although they have different ID
numbers, they are interchangeable.
