TM 9-2815-225-34&P 3-72.  INJECTION TIMING (Contd) LOCATION/ITEM ACTION REMARKS b.  Injection Timing Cylinder No. 1 (Contd) 9.   Crankshaft (17) (Contd) c.  Slowly rotate crankshaft (17) This reading of 0.0032 in. clockwise until piston dial (0.0813 mm) is actually 0.2032 in. indicator (16) reads 0.0032 in. (5.1613 mm) before zero since (0.0813 mm) before zero. piston dial indicator (16) will have reached over 0.200 in.  (5.08 mm) as the crankshaft (17) was moved to 45 degrees before TDC (21). Refer to view E.  Each revolution of the dial indicator hand represents 0.100 in.  (2.54 mm). d.  Read total travel of pointer on Each mark on pushrod dial pushrod dial indicator (6). indicator (6) represents 0.001 in. (0.025 mm). NOTE Engine assembly, as described in this section, is with the assumption that all units have been repaired or are new and are ready to be assembled.  During assembly operations, it is important to closely inspect each unit to make sure nothing has been overlooked during inspection and repair.  Plugs should be checked for tightness, parts kept clean, openings covered, and machined surfaces protected.  Application of any type lubricant should be performed from covered containers. The timing code for this engine is BM Big Cam I or BY Big Cam III, reference the engine data plate.  Code BM is used for CPL 324 and 327.  Code BY is used for CPL 393. BM Big Cam I (CPL 324 and 327) BY Big Cam III (CPL 393) Nominal  ............................... 0.053 in.  (1.35 mm)  ............. 0.070 in.  (1.78 mm) Fast  ......................................0.052 in.  (1.32 mm) ............ .0.069 in.  (1.75 mm) Slow  .................................... 0.054 in.  (1.37 mm)  ............. 0.070 in.  (1.78 mm) e.  Reading on pushrod dial If reading is not within limits, indicator (6) should be within follow the procedures in task c., 0.069-0.071 in.  (1.752-1.803 mm) Changing Injection Timing. for Big Cam III or 0.053-0.054 in. (1.35-1.37 mm) for Big Cam I. f.  If push rod travel is greater than limits indicated above, engine timing is slow.  If the push rod travel is less, timing is fast. c.  Changing Injection Timing CAUTION Never change cam follower assembly gaskets to correct injection timing until checking the following: Timing tool is correctly installed. Dial indicators are correctly adjusted. Crankshaft has been rotated in the correct direction. Screws for cam follower assemblies have been tightened to 30-35 lb-ft (41-48 Nm). 3-572
