Swing Arm Insertion

[waffey]

Hi,

after getting stuff back from the plating company, I started to install my swing arm. I am struggling to get the swing arm with the caps on to fit, not sure if is the powder coating on the frame that will not allow it to be pushed through to line up with the bolt. Anyone else had this issue and if so how did you get round it? I'm think maybe a bottle jack or scissor jack inserted into the fram just to push it out a little. That should be ok??

Not quite sure how to word this, but here goes. When I last removed my swinging arm, it was a long while before I replaced it and the memory bank failed for quite a while! I was at the rear of the bike and trying to push the bugger forwards into its correct location, NO CHANCE!!  After an eternity I remembered that you tip it slightly sideways, move it forwards so it's close to the back of the gearbox, get it nice and horizontal again, and then pull it BACKWARDS into the frame location. It's tight, but there again, it's meant to be. Have fun! Regards, Michael.

If you had the swing arm powder coated as well the coating on the ends can hold the plastic thrusts, if you are using original parts, or the flanges on brass top hat bushes too far apart making the swing arm impossible to fit.
And yes coating inside the frame can have the same effect and both together is really difficult.
A scissor jack used carefully would work

I would remove any powder coating from the inside of the frame where the swingarm contacts it. Do not force it in.  Once installed torque the swingarm bolt and make sure the swingarm pivots easily.

The swing arm will always pivot as long as the collar is the correct length as that should be pinched between the frame sides by the bolt

How thick is the powder coating?, when I was doing mine it should be a sung fit but not too hard to install. Remember that when torqued up it will pull together tight. If I remember when I did my bike I filed all the coating off and greased the cups and frame.
