cb350 rear wheel bearing retainer

[sandman28]

noticed today the rear wheel bearing retainer on my cb350 is a little broke / chipped on the inside (see pic)
seems like a bad idea to ride with it like that possibly... but does it provide and structural integrity etc?? besides keeping the bearing in place, which it is still doing, when the chain is tensioned and axle is tight there is ZERO play or wiggle in the rear wheel....

you already have a problem with the rear wheel bearing or the axle would not be off center like that dont ride the bike

till you fix that

thanks, if the hub needs replaced ill have to buy new hub (paint it), & SS spokes to lace to the xs650 rims im running, def not going to ride it. I will admit when I rebuilt the wheel the bearing retainer had a small chip in it that I kind of shrugged off (stupidly) I pulled the wheel, the axle appears straight, everything looks normal.... bearings seated fully etc. is it possible or likely that chip just got worn bigger and bigger, or the aluminum had a crack I didnt see.... or is likely in the hub itself ?

looks like the bearing is shot....even if the retainer was loose, the bearing should be centering the axle.....

well.... I figured it out, i bought new bearings from "All Balls" I know I checked the package because they sent me the wrong set for the front and I had to buy another. even found it on the shelf and its for cb350 68-73 rear. Anyway, what I am ashamed to admit I overlooked was the fact the bearings did not have same inner diameter. the bearing on the side with retainer is far to big, in the pic you can see I was able to stick a popsicle stick inside with the axle!!

that bearing gets an insert bushing

seems bearings are correct , .6304 on the sprocket side, 6303 on brake side, which is correct, correct? from looking at schematic it seems I am missing a spacer (#8 in photo in link)

yup

took the spacer out the rear wheel from a parts bike (the hub isnt useable) got everything back in order in my rebuilt wheel. but unfortunately the threads are so FU**** for the retainer I doubt I will get another one in. hoping to find a solution to get me through 4-6 weeks of weather good enough to ride. gonna take it the local shop tomorrow (mike wells racing in lexington ky) and see if he can provide any insight. I still feel that the retainer is not structural... it does not even seat down all the way to "hold" the bearing in place, seems like its more to hold to that seal in place. and the spacer on the axle on that side is what holds tight against the bearing..

well the good thing is you will be safe now

let us know how it turns out or what you need to get up and running

got it buffed out... what a dumb mistake! was able to clean the threads with a large tap of the same pitch, using it sort of like a file and thread in a new retainer . everything back in order,
