I did mark the position fo the gears. But when I was removing the camshaft they rubbed off. Long story short, I reread thru my book and was able to set it, I hope. The factory marks on the gears all lined up with the piston closeses to the fan at TDC. Was able to rotate the cam thru about 78 turns. and the factory marks would line up again. Since the only gear that was taken out was the one on the camshaft, I was able to rotate the other ones because, the way I was thinking was that the other gears would be in time. I just needed to get the camshat gear back in time with the others. Thank you!
