Ed Korn Cycle Works Swingarm seal removal tool

Removing these seals is a frustrating process.  Prying them out usually doesn’t get you anywhere.

I bought Ed Korn’s tool a while back and it can be used for pulling both the races, and the seals.

Here is how you use it to pull the seals.

Here is the tool assembled



I first cut out some of the seal’s rubber with a razor blade.
It was easier to get the tool installed that way.




Then you tighten the threaded rod with the allen fitting at the end of it.  By doing so, it expands the nut against the screws and presses them outward so they ‘catch’ under the metal part of the seal.

Then you install the collar, plate and washer and nut.


Once you begin tightening that nut, it will pull the seal out into the collar.
You can then loosen the nut, and break the old seal free with a few taps with a hammer.




Fork seal installation

A quick ‘How To’ install the fork seals.

You can pop the old seals out with a screwdriver or something else to pry them out. Just be cautious you don’t score or damage the inside of the fork leg/lower.

First make sure the fork lowers are clean.

Then sit the fork seals flat onto the top of the fork tube. It helps if you have a large socket, or something similar to help drive them in. I happen to have a 36mm socket that fits the diameter of the seal pretty good. It might be better if it was 34 or 35mm but it still did the trick.
I placed the socket over the seal, and tapped it in with a hammer. Here is a photo of the job with the seals about half way in:
