Primary Fuel Filter 12. Governor Plug REMOVAL PROCEDURE: (For a detailed disassembly  procedure  refer  to  appropriate  Service Manual. 1. Disconnect battery cables. 2. Disconnect   accelerator   cable   or   linkage   from outer injection pump control lever. 3. Remove  injection  pump  timing  pointer  plug  and gasket from left side of pump mounting adapter. 4. Rotate engine in normal operating direction until engine front cover timing pointer is approximately  90  degrees  from  top  dead  center dot on crankshaft pulley.  (The injection pump is driven   at   one-half   engine   speed.      Therefore, each    time    the    injection    pump    hub    mark    is aligned     with     injection     pump     timing     pointer, engine    should    be    on    number    one    cylinder compression stroke). NOTE:   If engine gear train was disassembled, verify that   engine   is   positioned   at   number   one cylinder compression stroke by: a. Removing valve cover. b. Observing  that  number  one  cylinder  intake and exhaust valve levers are loose. c. If  number  one  cylinder  valve  levers  are  not loose, rotate engine one complete revolution to approximately 90 degrees before top dead center. 5. Turn engine slowly in normal direction of rotation until timing mark on hub is aligned with injection pump  timing  pointer  (observe  through  mounting adapter,   Figure   19).      If   engine   is   turned   past timing  mark,  rotate  engine  counterclockwise  at least 90 degrees to remove gear train backlash. Rotate engine until timing mark and pump timing pointer are aligned. CGES-185-3 PRINTED IN UNITED STATES OF AMERICA Page 15
