INJECTOR SYNCHRONIZATION, FUEL SETTING, AND FUEL TIMING - CONTINUED
INJECTOR SYNCHRONIZATION - CONTINUED
Contact between injector rack head stop pin and shoulder on injector body is a solid stop. DO NOT use
excessive force once contact is made. Excessive force will cause damage to control rod.
Rotate control rod (7) in "A" direction until injector rack head stop pin (9) contacts shoulder on injector body (8).
Maintain position of control rod (7) and press ZERO SET button on indicator. This is zero-rack (FUEL OFF) position.
Allow linkage to spring back and then rotate control rod (7) to "A" position and observe zero position on indicator.
Repeat steps 14 through 16 several times until a consistent zero indication is observed.
Rotate control rod (7) in "B" direction. Release control rod and observe indicator (13) for an indication between 3.48 to
3.52 mm. Repeat this step several times to confirm consistent indication.
If indication is between 3.48 to 3.52 mm, go to step 22. If indication is not between 3.48 to 3.52 mm, go to step 20.
DO NOT loosen screws holding clamps on control rod. Loosening clamps will cause poor engine perfor-
mance and may damage engine. Clamps are factory preset onto shaft.
Turn setscrew clockwise to increase indication or counterclockwise to decrease indication.
Loosen locknut (19) and turn setscrew (20) clockwise or counterclockwise until an indication between 3.48 and 3.52
mm is observed on indicator (13). Hold setscrew (20) and tighten locknut (19).
Rotate control rod (7) in "B" direction and release. Observe indicator for an indication between 3.48 and 3.52 mm. If
indication is not between 3.48 and 3.52 mm, readjust setscrew (20).
DO NOT LOOSEN
If injector is synchronized, remove indicator fixture group (13) and install and tighten bolt (12) to 18 lb-ft (25 Nm).
Synchronize remaining injectors as required. When synchronization procedure is complete, remove synchronization fix-
ture, sync gage block, locking pliers and spring compressors.
