Swing Arm Bearings
LesterPiglet:
Needle bearings aren't ideal in that application. The needles need 360 degree rotation to stay lubricated properly.
jcknapp:
True Lester but when would you ever need to turn the swingarm 360 degrees?? I know people who race that strictly use needle bearings. The swingarm only moves up and down maybe 10-15 degrees?? IF even that? But whatever I was actually wondering how do I get these bushings out?? I am changing mine to needles but those bushings are really in there. Any advice Lester??

The problem is that needles NEED to turn 360 its the 10 to 15 that knackers them!!
to get bushes out use a hacksaw blade to cut through them, takes time but in the end it's the easiest way

I got the bearings in. Much smaller than the original. To me it seems like they should sit flush with the outside so the bearing covers will protect any kind of contaminants. I've also heard setting them back 5mm. Any thoughts??
Bryanj:
Depends on the year but you need the top hat thrusts and felt seals if originaly fitted to take the side thrust and fill the gap in the frame
