Cam chain tensioner bolt

(1/4) > >>

AndyD:
Hi again,
Another question on the cam chain tensioner bits.
The hole in the crankcase for the bolt to lock the tensioner has been repaired at some time with a M6 thread insert - it seems quite secure and thread is good but I wasn't sure how this should really be.
As I understand it the original bolt has M6 thread at the end and then a bit of M8 with a nut further towards the head.
Should the thread in the cylinder case be all M6 or a bit of both to fix properly.
Hope my rubbish description makes sense..

Cheers,
Andy

Bryanj:
All m6 the m8 is only on the bolt

AndyD:
Thanks Brian

Bryan,
Having cleaned everything up and gone through all the parts in the boxes I think I know what's gone on!
The thread in the crankcase for the tensioner setting bolt has been fitted with a dodgy M6 helicoil which was even a bit loose so I've pulled this out and the original thread is only partly intact.
The tensioner bolt also has a partly damaged thread so I guess between these two issues the tensioner would be likely to slip.
I think the PO has then made up an M8 'special' bolt and used this to push down the camchain adjuster from the end to tighten the chain manually'.
To fix this mess I've seen a repair 'kit' on ebay for a reasonable sounding £24 and which seems to include all the parts needed - any idea if these work?
I'll then get a new oil check bolt and washer as standard.
Hopefully this makes sense!
Cheers,
Andy

Bryanj:
Have you got the ebay number?
