INJECTOR SYNCHRONIZATION, FUEL SETTING, AND FUEL TIMING - CONTINUED
FUEL TIMING - CONTINUED
Remove indicator (35) and magnetic base from gage block (39) and carefully position it on top of tappet (40) for injector
(41) to be checked.
Carefully position indicator contact point on shoulder of injector (41). Ensure indicator plunger moves freely and con-
tact point does not bind on injector spring.
Refer to engine information plate, located at upper right-hand corner of valve cover, for correct fuel timing
setting. Setting must be within +/- 0.20 mm, as indicated on engine information plate.
If indicator displays correct setting or is within +/- 0.20 mm checking tolerance, no adjustment is necessary. Go to step
If indicator does not indicate correct timing dimension, loosen locknut (42) for adjusting screw (43).
Turn screw (43) until correct fuel timing is displayed on indicator. Tighten locknut (42) to 18 lb-ft (25 Nm) and check
adjustments again. If necessary, repeat this procedure until adjustment is correct.
Sequence for checking fuel timing dimensions is as follows:
Check and adjust fuel timing dimensions on half of cylinders with timing bolt installed.
Remove timing bolt and indicator group.
Rotate flywheel 360 and install timing bolt.
Install indicator group and check/adjust fuel timing.
Remove timing bolt from flywheel and install timing plug.
