swingarm bushing and collar questions?????

i understand what the grooves and the hole in the collar are for and that the grease fittings on the end of the pivot bolt provide the way to get grease to the collar. what i dont understand is how tight of a fit should it be. again should i just be able to press the collars into the bushings by hand? should they spin freely by hand? or should i have to use some force to press them in? im in the process of honing the insides of the bushings out with a hone attachment on my drill and dont want to take too much material off these bushings.

The steel thing HAS to be able to move as needed in the bearing surface of the swing arm and the swing arm bolt. THAT IS THE REASON FOR GREASE. ..........lm

Hey Deez - I used the bronze bushings from Nick at Ohio. The grooved parts slid in with about the same tolerance as an axle shaft in a wheel bearing - just enough to push it in there by hand with a little grease. I would use the swing arm shaft and the grooved bushing to gauge the correct tolerance fit. In my opinion the O.D. and I.D. tolerance should be the same.

Good luck!

thanks byrdman. so the bushings from ohio fit the cb77? i had a buddy of mine turn these bushings for me for about the same price and wasnt sure if the ones from ohio fit the cb77. whats wierd is that the collars fit into the bushings perfectly when the bushings were not pressed into the swingarm. once i pressed the bushings in, the collars have a hard time sliding into the bushings. so back to honing and thanks for the advice.

deez, how did your bushings turn out? I'm about to replace the well worn set on my '67 CL77. I'm wondering if yours were tight because the bushings distorted when you pressed them in?

I didn't notice my bushings were really worn until the last time I put the bike up....5 years ago. It's time to get her ready to ride again. Rick
