TM 5-3895-383-24 4. The intake and exhaust valves for the No. 1 cylinder are fully   closed   it   No.   1   piston   is   on   the     compression stroke and the rocker arms can be moved by hand.  If the  rocker  arms  cannot  be  moved  and  the  valves  are slightly open, the No. 1 piston is on the exhaust stroke. Make reference to charts for CRANKSHAFT POSITIONS   FOR   FUEL   TIMING   AND   VALVE   LASH SETTING to find the correct cylinder(s) to be checked/adjusted for the stroke position of the crankshaft when the timing bolt has been installed in the flywheel. NOTE: When the actual stroke position is identified,  and the    other    stroke    position    is    needed,    it    is necessary   to   remove   the   timing   bolt   from   the flywheel,  turn  the  flywheel  counterclockwise  360 degrees, and reinstall the timing bolt.
