Cam Chain Tensioner bits

(1/5) > >>

Hi,
Finally getting around to doing some work on the CB400F and have been going through boxes of bits and cleaning parts to start working out what needs replacing etc.
As a first area I've pulled together the cam chain tensioner parts and have a couple of questions - hopefully photos attached show relevant bits.
The horseshoe has been savaged by the cam chain and is stiff to move - is the damage too bad or is it OK to 'tidy' this up so the pivot moves smoothly and re-use?
The two chain guides are still flexible and no sign of cracks etc. - should these be replaced or OK to retain?
Looks like someone got creative with the special bolt and made this one up from a standard bolt so I'll replace this

Trying to keep budget down on this rebuild as the bike is a bit tired and lots of non-standard parts - had a good but hard life by the look of it - hence trying to reuse whatever is reasonable rather than bring back to original glory.

Cheers,

If you can get the horseshoe pivot to move freely under its own weight it ought to be OK the bolt/nut whilst not original will work but leak oil as there should be a sealing washer between nut and crankcase with a bigger thread on nut to bolt, the cushion looks OK  and the tensioner is not badly worn and can be changed without a majour stripdown anyway

AndyD:
Thanks
I’ll give the horseshoe a clean up and see if it frees up OK
Good news that other bits look alright

Cheers
Andy

I have freed these of by cutting a slit down both sides. It is always worth a go as, you have nothing to lose. It has to move very freely as in pick it up and gravity should make it drop with no help  ;)

How exciting. Its great that yourself and Waffey are working on your 400/4 engines at the same time..... Good luck to you both and I hope all goes well for you both .
