TM 55-1945-205-24-20271 00 20271 002.Center timing pointer (1).3.Rotate flywheel (2) clockwise until cast-in T mark (3) is approximately 1½ in. (4 cm) past timing pointer (1)4.Remove spark plug from #1 cylinder (4). (WP 0307 00)5.Install piston stop (5) in #1 spark plug hole (4).6.Turn center portion (6) until piston stop (5) contacts #1 piston.7.Lock piston stop (5) in place with ring (7).8.Hold flywheel (2) firmly against piston stop (5) and apply pencil mark (A) to flywheel (2) directly across from the timing pointer (1). 9.Continue to turn flywheel (2) clockwise until piston contact is again felt against piston stop (5).10. Use a pencil and apply mark (B) to flywheel (2) directly across from timing pointer (1).11. Remove piston stop (5).12. Install spark plug into #1 cylinder (4). (WP 0336 00)13. Using a scale, measure along the side of the flywheel (2) between A and B, determining the midpoint, and apply a pencil mark (C).14. If the T mark (3) and C are in the same location, the timing pointer (1) is aligned correctly.15. If the T mark (3) and C are not in the same location, turn the flywheel (2) to align the C mark with the timing pointer (1).16. Loosen screw (8) on timing pointer (1) to allow timing pointer (1) to be moved to T mark (3) on flywheel (2). Tighten screw (8).6573182"A""C""B"4
