Cam chain.. CB400f

(1/7) > >>

Integra99:
Happy New year all... well had some time to tinker and it seems my adjuster bolts are doing nothing at all. The lower lock nut (m6/m8) screws in then stops and does nothing. The blanking hole above containing the rod end also has no effect if push from the top with a screwdriver.

However the cam chain rattle is very minimal.. and once the revs hop up she sounds gorgeous.

So firstly does anyone have or notice a little noise at idle.. ?

I've had the camcover off last night.. the adjuster (sliders) are a little worn but minimal. When undoing the two (m6 / 10mm ) bolts the tensioner pops up, so when pushed down clearly the horseshoe tensioner is working as its pushing the opposing tensioner into the chain chain, but the chain is still a little slack. I fear my adjuster is stuck..

I really dont wish to split the cases right now.. I wonder if putting on the new cam chain that I have will suffice, assuming the adjuster is locked at a certain point. Any thoughts..

I have read some people lightly know the end of the rod to dislodge the adjuster but unsure of this!

Bryanj:
The only sure and safe way is to remove the lower case, fitting new chain with stuck horseshoe will only wear out chain quickly

Nurse Julie:
My adjuster was jammed which I didn't realise until I stripped the engine. Even with this I only had the most minute cam chain rattle at idle. Although you don't really want to split the cases, I think it would be prudent to do so, then you can see what the problem is. You can then also fit an endless cam chain instead of a soft link.

Integra99:

Is there anyway to see if the horseshoe is stuck without splitting the cases, can it be seen with the sump removed?  The horseshoe seems to move because pushing one tensioner down, applies pressure to the other side meaning it moving below, if that makes sense.

I think its just the adjuster (bar) is locked in one position.. 

Nurse Julie:
Not possible to see anywhere near the cam chain or horseshoe through the sump as everything you need to see is right at the front of the engine, nowhere near the sump.
