Cam timing verification

Featured Replies

The notches in the cam sprocket appear to line slightly advanced to the notch in the thrust plate. Is this an issue?

 

The crank timing is set to zero on the dial. I couldn't get a picture, but the intake and exhaust valves look closed to me.

 

The last picture is the one that shows my concern. The mark indicates that I may be slightly advanced. The timing chain and all associated parts are new. 6a3ffd367a63115d6b583d61cb82ea3b.jpg6efa36f5dff74dfc3cbe615e5585adf5.jpgd18cb783e53523a3375a0e492b8e1888.jpg86ff3d3b5b6ee1ef96be3a74749946f4.jpgb82a8ae0f105247b5705d4e4028e8d11.jpg

I think that's normal and it's fine. It's a tiny amount, a degree or two. And wear/stretch will retard it bringing it closer to nominal perfection.

Is the straight side, the driver's side, of the chain tight?  If you rotate things backward you can make it loose and it will do what your picture shows.  You can put a wrench on the sprocket bolt and tighten it up without turning the crankshaft.

Beside that, when it wears a little it will retard slightly.  But it's in range, looks good.

The driver's side of the chain is tight.  I found a few things on the internet stating that what I'm seeing is normal, but I feel better about the information one receives on here.
