Cam chain.. CB400f
Integra99:
Also the rod is well and truly stuck for my cam chain adjuster. The Horseshoe is moving but releasing all the lock nuts has done nothing. I have tried to knock it down gentle from the blanking hole but its not shifted, the hole isnt blocked because I can push oil from the top through and out of the adjuster hole. Bugger.. !

Just looking back through this thread and read this part again

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..
Are you sure the horseshoe is moving?. Could it be that when you push down on the top of the tensioner, it's not just the blade flexing which would mimic the horseshoe moving?. Also the opposing tensioner is just a guide blade and is totally independent.

Thanks Julie... ah yes looking at the diagram of course its only the one side thats affected. it looks to me that the horseshoe is actually not moving and I assume stuck in position and hence the rod is not moving. Thats a nuisance!
Nurse Julie:
When I stripped my engine, I undid the 2 x 10 MM bolts and my tensioner did not pop up. I had to fiddle with the adjuster on the front of the engine and the blade then popped up. Mine was seized at the pivot point on the horseshoe. Even though mine was seized, I still had very minimal rattle from the cam chain prior to stripping the engine.

Yes when I undid the bolts my tensioner popped up.. and the rattle is very minimal the bike runs lovely. But this is a fault and needs sorting, however I may only do 1000 miles on this bike over the next 12 months so I'm tempted to put my new chain and run it... my concern is I think the slack chain is at the end of its adjustment and may have worn into the horseshoe stopping movement. therefore the tensioner is at it most tensioned point.. potentially not good for a new chain.! The only way of freeing the horseshoe is to knock the rod down from the blanking point and see if it frees it at all.. otherwise its head off and engine out again.. !
