torque non adjustable rocker arms on 7.4L gen v

[KEVIN D TOBIN]

The info that I'm seeing is just put it back together and torque it to 40 lbs. , is it really that simple ? it doesn't matter where the cam is, in other words, when you go to do this all the the valves are closed, and it doesn't matter where the lifters are in relation to the cam lobe ? If that is so it really is easy !

I like to check the preload on the lifter when it gets reassembled. Get the lobe on the base circle and as your torqueing to 40# you want to see about 3/4 of a turn past 0 lash

I agree with scoflaw and like to 'see' the zero lash and the 1/2 to 3/4 turn. If you follow the firing order and make the adjustment at the top of the compression stroke, the cam will only have to rotate once - two rotations of the crank. In that position you can adjust both the intake and exhaust valves for that cylinder. To ensure you're at zero lash, as you're tightening the rocker arm spin the push rod. Once you feel the resistance in the spin you're at zero lash. There should be no vertical movement in the push rod. Then you should get to the 40# torque within 1/2 to 3/4's of a turn setting the lifter preload. Good luck!
