Injection Timing
1. Remove the injection pipes.
2. Set the speed control lever to the maximum fuel discharge
position.
3. Turn the flywheel counterclockwise (facing the flywheel) until
fuel flows from the delivery valve holder.
4. Continue to turn the flywheel slowly, and stop it as soon as the
fuel level at the tip of the delivery valve holder begins to
increase.
5. Check to see if the timing lines (1) on the flywheel is aligned with
the alignment mark (2).
6. If the injection timing is out of adjustment, readjust the timing
with shims (3).
NOTE
• The sealant is applied to both sides of the shim (soft metal
gasket shim). 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.), 0.30 mm (0.012 in.), 0.35 mm (0.014 in.)
and 0.175 mm (0.00689 in.). Combine these shims for
adjustments.
• Addition or reduction of shim 0.05 mm (0.002 in.) delays or
advances the injection timing by approx. 0.009 rad (0.5°).
• In disassembling and replacing the injection pump, be sure
to use the same number of new shims with the same
thickness.
• Refer to figure below to check the thickness of the shims.
(Reference)
• The alignment mark (2) of the injection timing line (1) is not in
alignment with the center of the timing window.
• The above mark (2) comes aligned with the center of the
flywheel housing rib.
