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.

Swing arm race and bearing install

Installation of the swing arm bearings.

Here is the order of the parts. The first part is a cup that only goes on the side of the swingarm opposite of the drive shaft. All it does is prevents grease from traveling into the crossmember of the swingarm. The other side does not require one.

First install that cup/plate into the swingarm and make sure it sits flush on the small lip.

I stuck the races in the freezer with hopes they would shrink enough to make the instal a bit easier.
The races can be driven in by hammering them in with a 30mm socket or if you have the Cycleworks race puller, the aluminum plate is also meant to be used as a driver.

Here is a 30mm socket (i know, the socket is upside down. I threw it in there for the photo):

Here is the Cycleworks plate being used as a drift:


Race installed:

Greased up bearing (be sure to pack it well with grease):

Then goes the collar with the flat side down, against the bearing:

Then goes the dust seal:

I prefer to install the collar through the rear of the dust seal, and then insert the dust seal into the swinarm:

One side done:

The process is exactly the same for the other side except for the grease protection cup.

Drive Shafts pulled

My local mechanic finally pulled the drive shafts(after nearly 2 months). I swung down and picked them up a week or so ago. I’m one step closer to having everything blasted and then powder coat…. If only my ‘day job’ would stop getting in the way…
