I overhauled my 65, 200 6 cyl mustang---I tried to fire it up a couple weeks ago and noticed it was not trying to fire, pulled cap off and saw cam not turning, I took off the front cover today and see the vertical pin in the front of the cam that fits in the slot in the chain gear was sheared, I took off the chain and gear and put the bolt back in the cam end and it spins reasonably easy I think, anyone else ever shear this pin?---looks like a pain to get the pin out of the cam now----I just covered it up for today and went back into the house!

Do you have the spacer on the cam? there should be a thick washer between the cam and the pin, if this was/is not there, then you would have tightened the cam against the thrust plate causing your problem.
I am thinking this may very well been what I did---I think I might have put it on the outside---wouldn't that have marred up the chain sprocket quite a bit??----it doesn't show any bad marks on it----maybe it was not turning over fast enough to cause any severe damage----any suggestions on getting the remaining dowel pin out??carefully drill the pin and put a screw in it and pull??---thanks for the reply.

I'd think you would have to have an awful lot of torque on the starter to spin a cam sprocket that had been squished/tighten into the front of the block.

This happened to me too. However, the cam sprocket retaining bolt backed out over time. The chain got sloppy and I kept adjusting the timing (thought the balancer spun). Finally the pin sheared. I got a replacement pin and spacer from Schneider Cams in San Diego. They have a mountain of cams, parts and peices.
I would think that the pin would be a standard sized SAE steel pin you could order from any place (mcmaster-carr or such) is it not?
