TM 10-3930-671-24 11. Turn  the  injection  pump  gear  until  the  internal timing marks are lined up (See Below). Turn the injection pump gear until timing mark is aligned with the pointer 12. Guide the injection pump into position and install the     three     long M10 mounting bolts, lock washers,    and    nuts    that    secure    the    adaptor mounting  plate  to  the  engine.    Torque  the  M10 bolts to 25-30 lb-ft (34-40 N•m). 13. Inspect the internal timing marks again.  The two marks  should  look  like  one  unbroken  horizontal line.    If  not,  you  must  judge  as  to  whether  the pump gear is one tooth or more out of time or if a  minor  rotation  of  the  injection  pump  body  will align  the  marks.    If  the  marks  are  far  apart, repeat   step   12   because   the   pump   gear   is probably out of time.  If the marks are very close together,  rotate  the  body  of  the  injection  pump one way or the other until the marks line up. 14. Torque   the   three   M8   bolts   that   fasten   the injection pump to the adaptor plate to 15-18 lb-ft (20-24 N•m). 15. Recheck  the  timing  marks  after  eliminating  the backlash and play that may be in the timing gear train.    This  is  done  by  rotating  the  crank  pulley counterclockwise approximately 1/4 turn (viewed from  the  front).    Then,  rotate  the  crank  pulley clockwise until it is back to the prescribed timing position.   Check  the  internal  timing  marks  once again and adjust if needed. 16. Install the timing hole cover and gasket onto the injection pump housing. NOTE Leave  any  two  of  the  fuel  line  nuts loose  at  the  nozzles  for  Bleeding  the Fuel System. 17. Install the high-pressure fuel lines and torque the fuel line nuts to 20-25 lb-ft (27-34 N•m). 18. Reconnect all electrical wires; linkage rods; low- pressure fuel lines, etc. 19. Bleed the fuel system. F-156
