I have a couple of people helping me but thought I'd ask here.
I was trying to tighten the right hand camshaft sprocket and I seem to have made the sprocket jump a tooth.
I did the first bolt and I noticed a bit of movement in the chain and the sprocket moving slightly , when i moved onto the second the chain was moving again
and I head a noise like the sprocket had jumped teetch . I checked timing and it was out by at least a tooth.
the timing chain has just been replaced. My friend was sure it could not have jumped out by it has . He was saying that the chain cannot go slack to allow it but I have noticed that the tensioner does move back in a bit.
another friend says it is not surprising that this has happened and said I should have held the sprocket in place. I have a tool that stops the flywheel moving, would that have prevented the sprocket fromjumping like that?
