Injection Timing
1. Remove the stop solenoid.
2. Remove the injection pipes and nozzle.
3. Set the speed control lever to maximum fuel discharge position.
(Reference)
• Turn the flywheel with screwdriver.
NOTE
• For V2203-M and V2403-M-T the pumps have a displacement
angle. In adjusting the injection timing, pull the stop lever
(2) from its free position by 0.267 ± 0.035 rad (15.3 ± 2 °)
toward the stop position.
4. Turn the flywheel counterclockwise (facing the flywheel) until the
fuel fills up to the hole of the delivery valve holder for 1st cylinder.
5. Turn the flywheel further and stop turning when the fuel begins to
flow over, to get the present injection timing.
6. (The flywheel has mark 1TC and four lines indicating every 0.087
rad (5 °) of crank angle from 0.175 rad (10 °) to 0.436 rad (25 °)
before mark 1TC) Calculate the angle which the center of the
window points out.
