  • Rotate crankshaft until mark on torsional damper aligns with center or ``O'' mark on timing tab, attached to crankcase front cover, and piston of No. 1 cylinder is at top dead center of compression stroke. This may be determined by placing fingers on the valves for No. 1 cylinder as timing mark on damper nears the ``O'' mark on front cover. If valves do not move, engine is in the No. 1 firing position. If valves move, the engine is in the No. 6 firing position and should be rotated an additional revolution.
  • With valves in No. 1 firing position, adjust exhaust valves 1, 3, 4 and 8, and intake valves 1, 2, 5 and 7 as described in step 3.
  • Back out adjusting nut until lash is felt at pushrod, then turn adjusting nut inward until all lash is removed. When all lash has been removed, turn adjusting nut in additional one turn. Zero lash can be determined by rotating pushrod while turning and adjusting nut.
  • Rotate crankshaft one revolution, until pointer ``O'' mark and torsional damper mark are aligned. With engine in this position, adjust exhaust valves 2, 5, 6 and 7 and intake valves 3, 4, 6 and 8.
