i'm having a hard time finding any definitive dimensions on a CB350 twin's two rear wheel bushings, part numbers 42311-349-690 + 42313-286-000. I ripped my rear wheel apart and have both of them (learned the hard way about the bearing collar that's no longer available), but they are different lengths/heights. I have tried everywhere to find a length of each but cannot, does anyone know which one goes where?

thanks in advance,

this doesn't help. it only shows one of the bushings, #5; the other one is on the Brake page. in the pictures they both look the same, and physically they are both identical with the exception of the length. i just cannot find any definitive spec's on the two p/n's to determine which one is which.

The spacer that runs on the sprocket side will have a shiny ring where the seal runs on it.

Why can't you just put them in the way you "think" they should go and measure the chain alignment?

It's either going to be right or you'll need to swap them over.

It's not rocket science.

LOL, it's not "Rocket" science, but it IS still "vehicle" science. and my arse is over the two wheels of the vehicle... actually, it will EVENTUALLY be. I'm in the middle of a rebuild and have the frame on a cart while mocking up the front and rear end. No chain to line up, and i think even with it on there the bushings are within a few mm's of eachother that i wouldn't be able to tell Line-of-Sight. also, don't have rims on the hubs either, so i cannot check alignment at the seat- or chain-stays. i cannot believe no one has encountered this problem??

Hey, it's not like going to Las Vegas. You have a 50% chance of winning the spacer challenge. :)

Don't buy a bevel drive Ducati L-twin to pull apart, without measuring all the shims as you operate.

But then, how hard could it be to rebuild if you have pictures to go by?

It's not something you have to worry about right now. Get your wheel back together, slap the axle and spacers on and mount it to the swingarm. Then when you put the chain on and are ready to test ride it revisit the issue.
