Hi, i am looking for some assistance.
I have just rebuilt one of te two heads and when tightening the tensioner base plate the chain has gone extremely tight, i can’t see where i have gone wrong, if at all.
ANy help or advise would be greatly appreciated.
Have you locked the tensioner arm with a bit of wire thru the hole(s) in the side before installing? Once fitted you then remove the wire(I use a small allen key) to allow the spring to take up the slack.
push down on the top of the locking lug with a screw driver and pull up on the roller end with a hooked bit of wire to losen the timing chain adjuster you can see both from above the head with a tourch good luck
