Lost Camshaft Bearing caps.
« on: May 12, 2014, 07:44:35 PM »
Was cleaning up the head components for my second build, and realised I've lost the cam bearing caps, I remember numbering them and stringing them together, but I'm pretty sure they ended up in a box I let the tatters take!!!!

My loss, anyone got a set they'll sell me?

Cheers.

The ones I have owned K0 and K7 have been stamped with a letter/No. code to match together so I think real care would be needed to use caps from another machine. Best bet would  be to buy some  decent  cam  towers complete. At least Honda had the decency to allow us to replace the cam bearings on the 750SOHC unlike on the CB400/4 etc !

Thanks guys I know its not ideal, but I can line bore the bearings, if I can get complete carriers I will, but I have a lead on a set of caps....

Why is it the Mrs always seems to find out when I've made a silly mistake like this, and cost myself money.... :-[ :-[ :-[

Never get that from her in doors. I always get: "when are you going to finish that bike so i can give it a thrash". You old boys do not know how good you have got it.

Ash, they are all numbered/letterd even the early ones but i have found from experience that it is possible to swap just the caps, sometimes they fit better by turning them round.

i have found that if when you drop them on there is no "step" from cap to carrier at the bearing surface they will run happily. Way back when the shop i worked for used to keep on the shelf carriers, cams and followers for two engines and we had a man who would spend hours grinding the cam bearing surfaces and boring the carries then fitting pegged half roun bronze bushes, but he gave up years ago

Ha, excellent, although "I was out shopping all day" is a bit of a worry isn't it?
