Now I think I understand why the 360 rotation is necessary! With the cam pulley arrows lined up with the marks, there is valve spring tension on the right pulley only causing it to want to move and hindering the spring on the belt tensioner from auto adjusting the belt tension??? You're saying that the 360 move is so that the valve spring force applied to the right cam pulley is released, facilitating correct functioning of the tensioner spring. Does this valve spring pressure then transfer to the left side cam pulley after the rotation? If so, I believe I'm almost there. If there is no movement of either of the cam pulleys OR the crank during the belt removal and installation process shouldn't the T-1 mark be correctly aligned after the belts are reinstalled and the tensioner bolts tightened down??? If so, are the instructions to recheck and rotate the engine 2 full turns and recheck again simply to verify the procedure was done correctly? Or is it possible for something to have slipped out of alignment during the install? I assume the only 3 ways for this to happen Is to (1) turn the crank with the belts off or (2) turn the cam pulleys with the belts off OR (3) not secure the right cam pulley with the offset wrench/Wiretie trick BEFORE loosening the tensioner bolts (which is actually a variation of possibility (2)....That being the case, the next question scares me a bit. If something is mis-aligned with everything tightened down won't turning the crank cause the valves to strike the piston tops? If so, How do you backstep to rectify this crank/cam mis-alignment. (I'm assuming you hear the valves click against the piston tops!) Do you then turn the crank bolt the opposite direction to make the valve come away from the piston top? One more question! How did you guys learn all this stuff?<grin> Oh yeah, and how much pressure should I expect to apply to the crank bolt to get the engine to turn over? It seems like turning everything would require a long wrench and some pretty serious brute force. Would getting the rear wheel off the ground, placing the tranny in 5th gear and rotating the rear wheel be easier? Thanks a bunch Octane! This is good stuff!
