Rotate the crankshaft opposite normal engine rotation
(counterclockwise) slightly, until the dial gauge does
not move any longer.
Set the dial gauge pointer to 0.
Rotate the crankshaft in the normal direction until the
dial gauge reads 1.0 ± 0.3 mm [0.04 ± 0.01 in].
Look at the pointer on the crankshaft. It should point
to the timing mark in degrees as stamped on the
dataplate. The timing marks on the crank pulley range
from 6 to 14 degrees in two degree increments.
NOTE: Check the values on the data plate. Values
may change as new ratings are developed.
NOTE: The gauge reading ±0.03 mm [0.001 in] is
equivalent to ±0.5 degrees fuel injection
timing.
NOTE: The crankshaft must be rotated in the
normal direction (clockwise looking from
the front of the engine) without stopping.
If the dial readings are not within the standard value,
loosen nut. Adjust the fuel injection timing to within
standard value by rotating the injection pump body.
Tighten the nut.
