3. T
urn the flywheel counterclockwise (viewed from
flywheel
side)
until the fuel fills up to the hole of the
delivery valve holder (3) for No. 1 cylinder.
4. After the fuel fills up to the hole of the delivery valve
holder for No. 1 cylinder, turn back (clockwise) the
flywheel around 1.6 rad (90°).
5. Turn the flywheel counterclockwise to set at around
0.44 rad (25°) before T.D.C..
6. Slowly turn the flywheel counterclockwise and stop
turning when the fuel begins to come up, to get the
present injection timing.
7. Check to if the timing angle lines on the flywheel is
aligned with the center of timing window (2).
The flywheel has mark [1TC], [10] and [20] for the
crank angle before the top dead center of No. 1
cylinder.
8. If injection timing is out of adjustment, readjust the
timing with shims.

injection pump.
4. Install the injection nozzle (2) jetted with the proper
injection pressure to the injection pump pressure
tester (1).
(1) Injection pump pressure test-
er
