Hydraulic Lifter Adjustment (At Engine Overhaul)

With No. I cylinder at TDC firing position, adjust Exhaust Valves 1-3-4-8 and Intake Valves 1-2-5-7 as follows:

1. Back off rocker arm stud adjusting nut until there is play in pushrod, then tighten nut until pushrod-to-rocker arm clearance is just removed.
2. Tighten nut an additional 1 turn (places lifter plunger in center of its travel).
3. Crank engine I complete revolution so No. 6 cylinder is at TDC firing position and adjust Exhaust Valves 2-5-6-7 and Intake Valves 3-4-6-8 in same manner.
