towel, wipe the tips of the valves clean and apply lube to them where the rocker arms will come in
contact with them. Also be sure to check the valve stem tips for excessive wear. Next, install the rocker
arms. Do not tighten the adjusting nuts down before the proper sequence is performed. On engines with
shaft mounted adjustable rocker arms, back off all adjusters completely before installing the assembly.
Make sure the pushrod is in the lifter and the rocker arm seat when making valve adjustments.
4. Adjusting pre-load: Turn the engine in the normal direction of rotation. Start with cylinder number one
(1). When the exhaust valve begins to open, adjust the intake valve to the correct pre-load. To reach
zero, take the pushrod between your finger tips and move it up and down while you tighten down the
rocker arm adjusting nut. Once you feel no more vertical slack, you are at zero pre-load. Make sure the
pushrod is in the lifter and the rocker arm seat when making valve adjustments. Then tighten the
adjuster nut zero to 1/4 of a turn of the wrench. Next, you can move on to the exhaust valve on the same
cylinder. Now, rotate the engine over again until the intake valve reaches maximum lift and is almost all
the way back down. Then set the exhaust valve using the same method as the intake (zero to 1/4 of a
turn). Continue adjusting the valves on each cylinder in this manner until all valves are adjusted.
