Timing of cam chain correct? (solved)
RBoss:
Hi all,
I'm putting together the top end of my engine rebuild and I am not sure if the way I am putting back my cam shaft on the chain is correct.
I am trying to make the top dead centre of cilinder 1&4 correspond with the cam shaft but I am having trouble lining up the holes of the cam sprocket then. This is the best I am making of it now. What would you say?
Also the cam chain is very tight and it is difficult to fit it on the sprocket, i have to turn the tensioner "loose" in order to be able to fit the chain on the sprocket. Is that normal? (It is a new chain)
I have two situations:
1) either the cutout in the camshaft is not entirely horizontal to the top face of the head while the T-mark is correct

2) the cutout is horizontal but the T-mark is not correct

Am I doing something wrong?
RBoss:
Got it! Is was one tooth off... :-X
Bryanj:
Correct it was 1 tooth out and yes they are a swine to fit when chain is new. You do know that you do not use a screwdriver in the adjuster slot dont you

I didn't know that, I suppose one should adjust the tensioner just by loosening the bolt and retightening it again and let the spring to its work? I guess I won't be adjusting mine soon as it is a new one?
Bryanj:
If you have a new tensioner blade the sideplates of chain wear two grooves into the rubber till rollers touch so adjust at 500 miles after rebuild same as oil change then every 1500.
DO NOT turn engine with a spanner on the big nut at points, lossen adj nut, put weight on kickstsart until crank is about to turn then whilst holding cranck tighten nut
