Tips on installing swingers shock mount bushings and needle bearing conversion

<< < (2/3) > >>

alexdecker:
My Tourmax needle bearing conversion didn't come with any seals. Just the roller, needle bearings and end caps. Does anyone know how far into the swingarm I am supposed to sink the needle bearings, since it doesn't seem like I need room for seals?

Buy a long 10mm threaded stud bar, make sure it's longer than the swinging arm pivot tube AND the needle roller, thick washers and just pull the bearings into position, use a good fitting socket afterwards to sink them into the arm. Same trick with the rear bushes, they are easier to get in than out, if the stud bar is long enough you can pull them both in at the same time. . Protect your new paintwork from the washers by using some rubber etc underneath, something like a folded piece of inner tube.

Could I potentially use the bolt I already have for attaching the swingarm to the frame, and just fill the remaining space with washers to make it fit? Or will I remove the bolt and threads etc?

Oddjob:
You could use the swinging arm bolt but you'd need a lot of washers.

Doing this today. But how in the world do you make it go in straight? Every time a put on a little pressure, the stud bar moves a bit off center, and the bearing gets out of a straight line. Got it in a little bit now, but it got crooked and stuck.

Any tips?

alexdecker:
Okay, never mind. Drove them in there, but can't get the collar through, so obviously twisted them when installing them. Which sucks.

I wonder if I can just hammer them out and put in bronze collars instead? As the needle bearings are ruined now :(
