Injection Timing Adjustment (BTD 8.0KW,
IO.OKW,
11.OKW
& 12.5KW)
Incorrect fuel injection timing will result in hard engine starting and poor engine performance. Adjust the
injection timing as follows:
NOTE: The fuel lever (throttle) must
be
in the Run position while making the
adjustment or
no
fuel will
flow
to the
fuel
injection pump.
Refer to the cutaway view
of
the fuel injection pump and remove the high-pressure fuel line from the
No.
I fuel delivery valve holder. Remove the
No.1
fuel delivery valve holder and remove the delivery valve
spring beneath the holder. Reinstall the delivery valve holder and reattach the fuel line. Disconnect the
opposite
end
of
the
No.
I fuel line (from the
No.
I fuel injector) and
tum
the fitting away from the
injector, in order to catch the fuel as the pump operates.
Rotate the crankshaft clockwise (as viewed from the front), catching the fuel from the No. I fuel line, until
the instant the fuel completely stops flowing (no drips). At this instant, the
19°
BTDC timing mark on
the crankshaft pulley should be directly aligned with the timing indicator on the front
of
the cylinder block
(see the illustration on the next page).
