Swing arm race and bearing install

2012 July 28

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.
