Yep, definitely something weird going on. I'm working on the assumption that both Sliver and CMS get their stock from the same supplier and are incorrect 🤔🤔🤔

Being as its plastic it may close up enough but you would have to fit it to check, have you measured the od of the bush and id of the arm?

I'm not able to check I/D of the arm Bryanj as me, being of the cautious persuasion, didn't want to remove the old bushes before I had a chance to check the new ones for size. Just as well as it turns out, at least now I can rebuild using the old bushes/coller. It was a 50/50 call whether to replace the bushes.

Thanks for your help guys. I have asked CMS for a refund on the parts but I have had no response, it seems to have fallen on deaf ears!

My apologies are due to CMS as they have refunded me for the bushes, although they still insisted that they were the correct part.

I had the same issue year ago (Julie remembers well) - too big ID - mine were 21.7, they had free play on new collar. After I ordered new from producer all was OK

Interesting Erny, which producer did you get parts from?

Yes I do remember that Erny, where did you get the ones that were the incorrect size, was that CMSNL as well?

No Erny, James didn't get those from me. I have supplied James and lots of other forum members with sets of Bronze Bushes and they fitted them with no problems that I have heard of. We have also fitted the ones I supply to all our own SOHC/4's and they are a perfect fit every time.
I can't remember how many sets I have sold on ebay and through Facebook sites but it's getting somewhere near 200 sets and maybe more with only good feedback.

They are all the same part number Bryan so fit all the CB SOHC/4 models as well. My supplier also has them labeled as CB750/900 and they are the ones I have sent you before.
