Checking and Adjusting Injection Timing
1) Remove the injection pipes.
2) Set the speed control lever to maximum fuel discharge
position.
3)
Turn the flywheel couterclockwise (facing the
flywheel) until the fuel fills up to the hole of the
delivery valve holder for 1st cylinder.
4)
Turn the flywheel further and stop turning when the
fuel begin to flow over, to get the present injection
timing.
5)
[Fl mark type] (The flywheel has marks TC and Fl for
each cylinder on its outer rim) If the Fl mark does not
align with the projection in the window on flywheel
housing, add or remove the shim to adjust.
6)
[Markless type] (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 projection in the
window points out. If the calculation differs from
specified injection timing, add or remove the shim
to adjust.
• NOTE
• Apply liquid gasket (Three Bond 1215 or equivalent) to
the shim, when reassembling.
(Reference)
• The timing advances by removing 0.15 mm (0.006 in.)
of shim and retards by adding one, approx. 0.26 rad.
