TM 9-2815-225-34&P 3-72.  INJECTION TIMING (Contd) LOCATION/ITEM ACTION REMARKS b.  Injection Timing Cylinder No. 1 (Contd) 5.   Crankshaft (17) Slowly rotate several degrees The piston dial indicator (16) clockwise and counterclockwise and pushrod dial indicator (6) to ensure piston is at TDC (19) will move in the same direction and pushrod dial indicator (6) when piston is on compression is at TDC.  Refer to view B. stroke. NOTE Always set dial indicator at zero at TDC with crankshaft having just been rotated in the direction of normal rotation (clockwise). 6.   Piston dial indicator Loosen and adjust face of piston thumbscrew (3) dial indicator (16) to align zero with pointer.  Tighten piston dial indicator thumbscrew (3). 7.   Crankshaft (17) Rotate clockwise 90° after Piston follower rod (11) will be TDC (20).  Refer to view C. near bottom of its travel. 8.   Pushrod dial indicator Loosen and adjust face of push- thumbscrew (5) rod dial indicator (6) to align zero with the pointer.  Tighten piston rod dial indicator thumbscrew (5). 9.   Crankshaft (17) a.  Rotate counterclockwise This step is necessary to remove past TDC to 45° before gear backlash and provide more TDC (21).  Refer to view D. accurate dial indicator readings for the next step. b.  Slowly rotate clockwise to 19° before TDC (22) until piston follower rod (11) is almost in contact with piston dial indicator stem (15).  Refer to view E. 3-570
