Yanmar YM135d - Fuel Injection Timing

44) The flywheel is now turned exactly 180"
from this position clockwise (that. is, the TDC
position at which there
is compression in the
other cylinder).
(5) The procedures described in (2) and (3) are
repeated for No. 2 cylinder to adjust the valve
clearances to 0.0078 in. (0.2 mm).
3. FUEL INJECTION TIMING
The timing of the injections from the fuel pump
delivery valve is checked in the following order
with fuel being fed to the fuel pump by
a hand
oiler.
(1) The No. 1 cylinder is set to the TDC posi-
tion where there
is compression.
(2) The flywheel is moved back and forth in.
small increments.
(3) The flywheel is stopped at the very moment
that fuel
is discharged from the delivery .valve.
(4) The angle between the stamped mark on the
crankshaft V-pulley and the indicating pointer on
the gear case at the time fuel
is discharged is
checked.
(5)
Correct fuel injection delivery timing is when
the stamped marking and the pointer are lined
up, which
is 24 degree before TDC.
(6)
If the fuel injection timing is lagging, the
timing is adjusted by removing the
shim(s), and
if
it is ahead, add the shim(s).
Every 0.0039 in. (0.1 mm) shim provides approx-
imately 1
degree of variation.
