Hi guys
I recently replaced my camshaft as the old one had snapped a lug for the mounting bolt (had a crack and it failed during assembly).
So, I bought a new one and went to install it. I rotated the rotor to the LT mark, and dropped the cam sprocket slightly so the chain came off of the bottom sprocket. Then rotated so the line on the sprocket was horizontal. And bolted it to the camshaft with the advancer lobe facing up.
Put the first cam bolt in, put the 2 outer cam bearing holder covers on, and then put the tensioner on. Released the tensioner bolt so it took up slack, then retightened. Rotated the crank so I could put the other cam bolt in. All seemed good. Everything was lined up correct,y and was tight.
But everytime I rotate the crank to check its all fine (rotate 2 full rotations and check timing marks), they seem to be a tooth ahead. Everytime. So I can only rotate it about 3 times before Im hitting valves on pistons.
It doesnt physically skip a tooth off of either of the sprockets, well...im pretty sure it doesnt anyway. So I have no idea what the hell is going on!
Can anybody chime in?
Cheers, Charlie.
Edit -
Just to add more info, it has a skinny cam (will check any stamps or marking etc tomorrow)....312 rockers, and a cam sprocket with 312 on too. DID Endless camchain.
