Title: Wanted CB550 camshaft sprocket
Post by: Ashdowner on April 14, 2017, 05:22:18 PM

For goodness sake. I love my CB but it does cause me pain. Always wondered exactly why my 550K3 engine had been rebuilt and now I know why. The cam chain must have broken which makes sense of the damage to the head in one cylinder, but what I didn't realise and have only just noticed is that the thrashing chain had taken a big chunk out of the camshaft sprocket. It has worked fine up to now and may last forever more but I'd just be worrying about it if I put it back. Has anyone out there got a sprocket please? I think the sprocket was standard on all 550F and 550K bikes.

Don't hold your breath and I'm making no promises but I may have one off of my old spare K3 engine. I will look sometime tomorrow. It may also be knackered too but I wont know until I find it.

Thanks for looking Julie and I can guarantee that unless you've put it in a vice and hit it with a sledgehammer it's not more knackered than mine. It's like Jaws (a la James Bond) decided to snack on it. They're bathed in oil all the time so they shouldn't really be knackered. (Is knackered a technical term? Never found it in any workshop manuals).

Knackered is a perfectly good technical term but if in the company of delicate ears crodged is better!

I'm not that delicate. Just trying (and failing) to inject humour into yet another frustrating day.

'Knackered' is a totally appropriate word, one used frequently in Medical terminology, everyone knows exactly what you mean when you say it.

I don't go looking. They seem to find me. But hopefully another week and I should be mobile again.

Thanks to Mattgray for the sprocket. Now installed and a couple of days away from having a working bike (all fingers crossed)
