Thermostat Valve Opening Temperature
1. Suspend the thermostat in the water by a string with its end
inserted between the valve and seat.
2. Heating the water gradually, read the temperature when the
valve opens and leaves the string.
3. Continue heating and read the temperature when the valve
opens approx. 8 mm (0.315 in.).
4. If the measurement is not within the factory specifications,
replace the thermostat.

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 gas 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.

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.
