ARMY TM 9-2815-257-24 AIR FORCE TO 38G1-128-2 MARINE CORPS TM 10155A/2815-24/3 4-19 4-11.  FUEL INJECTION PUMP MAINTENANCE  -  cont. 4. Adjust  fuel  injection  timing  in  accordance  with step E before connecting fuel pipe (1) to injection pump (2).    E.    FUEL INJECTION TIMING ADJUSTMENT. 1. Remove   flywheel   housing   (Para.   3-13).   Dis- connect fuel pipe (1, Figure 4-12) from injection pump (2). 2. Set   governor   speed   control   handle   to   RUN position. 3. Rotate  flywheel  one  revolution  in  the  clockwise direction   until   T   position   mark   on   flywheel matches V mark off line on cylinder body fin (see Figure 4-13).  This is the top dead center (TDC) position.   There should be some fuel coming out of the fuel injection pump.  If fuel is not present, rotate the flywheel another revolution clockwise. 4. Turn     flywheel     counter-clockwise     about     30 degrees from T position mark. 5. Slowly  turn  flywheel  clockwise  until  fuel  flows from injection pump, then stop rotation. 6. Use   timing   marks   on   flywheel   to   determine flywheel  position.    Marks  are  5  degrees  apart.   Flywheel should be 16 to 18 degrees before TDC position.    Therefore,  the  V  mark  off  line  should be aligned between the third and fourth flywheel timing marks before the TDC position mark. 7. Repeat  steps  4  through  6  two  or  three  times  to make  sure  reading  is  accurate.    Fuel  injection should  begin  when  flywheel  is  rotated  16  to  18 degrees from TDC position mark.
