Hi
I recently purchased an old 1982 honda CB400n in quite good condition, except the rear wheel, or rim I should say. The seller provided a replacment rim, but it is sadly not the same as the one on the bike. (Different colour and size? See pictures)

so the rear wheel was not broken per say, as it was in daily use when I bought it, until…! I hit a pothole and everything came loose. After closer inspection, it seems as the collar or spacing which ties the rear sprocket and chuson pads togherer as broken :-(

I am now trying to reuse the collar from the replacment rim, but it seems as it might be stuck, or not supposed to be removed.

Is there anyone in this forum, who has removed or had this problem, which knows what to do? :-O Are mye only options a new rim? Or could I salvage the parts from my replacement rim?

this is the replacement rim.

and this is the original rim.

the damage.

collar part from replacement rim.

Exploded view of replacement rim, I pressume.

thanks in advance for all help! And please excuse my poor english, as it is not my native language.

Happy riding, best regards CB400norway :-D

All you can do is replace the whole wheel assembly, those Comstar wheels cannot be disassembled.

The constant wheels can be did assembled, but very very very difficult to reassemble, in fact do not !!!?!

Picture shows a sprocket on the iron spigot minus the replaceable collar/distance piece.

Try davidsilverspares, some new sprockets have the collar/distance piece built in, some don't.

Forget the idea of replacing the alloy rim to use on your bike, get another wheel from eBay etc

Hi all!

the only way to fix this problem, is as quotet above. Use a new rim, it is unsalvageable. Sad, as I quite like the gold ones (hit me up if u want to sell ;-))
Thanks for the quick replays, ride safe!

I assume you got a replacement wheel ?

On your weekly inspections, the wheels should be checked.

On inspecting the wheels and checking for wheel bearing "play" , if any "creeking" is heard, INVESTIGATE ! as the wheel may be begining to get loose, you do not want the wheel "spokes" to come off when riding and the wheel break up.

Yes, I did swapnit out for a replacement wheel.

Small update!!

Tried to use a press to push out the steel collar/center of the rim, just to see if it was doable. It was not…!😂 see attached picture.
This is to inform anyone that is thinking about doing the same.

have a nice day
