Injection Timing
1. Remove the injection pipes.
2. Remove the engine stop solenoid.
3. Turn 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
1.57 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 see the degree on flywheel.
The flywheel is marked "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.
NOTE
• The liquid gasket is not required for assembling.
• Shims are available in thickness of 0.20 mm (0.0079 in.),
0.25 mm (0.0098 in.) and 0.30 mm (0.0118 in.). Combine
these shims for adjustments.
• Addition or reduction of shim (0.05 mm, 0.0020 in.) delays
or advances the injection timing by approx. 0.0087 rad
(0.5 °).
• In disassembling and replacing the injection pump, be sure
to use the same number of new shims with the same
thickness.
