Cb550 k3 primary chain
« on: November 01, 2022, 08:26:51 PM »
hi, can anyone tell me if it is possible to determine if the primary chain has too much play in it by rotating the clutch basket clockwise and anticlockwise and measuring the free play ?

I tried lifting it off the teeth on my 400 - mine was shot. This was confirmed by the Tank Track test when I removed it.

No it cant but remove the sump and see how much lay you can feel, probably lots, plus how much its eaten into the main oil gallery

I've taken the sump off, there seems loads of play but I can't see any signs of wear and there's filings in the sump.

With the primary chain you don't tend to see wear, they look fine until they break. If the chain is sloppy then replace it along with the primary drive damper rubbers, don't buy a genuine Honda primary chain, the Kawasaki chain is exactly the same and half the price.

The tank track test consists of removing the chain and laying it on a flat surface similar to a tanks tracks, the more links that touch in the middle the worse it is, a new chain won't even touch unless you push down on it.

I'd remove it quickly BTW, filings in the sump generally mean it's eating it's way through the oil gallery which sits under the chain, a clear indication it's really buggered.

Missed a word out, should have read "there's no fillings" in the sump.
Which kawasaki chain is the same?
Thanks Ian

We'd all like to know that Phil. It will be a finite source regardless as Honda have discontinued them.

Yup, I went for the Kawasaki chain as the Honda item was just too expensive.

23131-323-000 was not discontinued, it was superseded to 23131-323-003 and now has been superseded to 23131-426-003.
You need to look a little far afield than Sliver or CMSNL. Around £46 retail in Japan and also the primary rubbers are cheaper. If you open a trade account you can get a 25% to 33.3% discount  ;)
