1.Preparation
(1)Close the fuel filter valve.
(2)Disconnect the No. 1 fuel injection pipe
from the cylinder head and injection pump.
(3)Remove No. 1 delivery valve holder from
the injection pump. Remove the delivery
valve and spring from the holder. Restore
the delivery valve holder only to the
injection pump.
(4)Connect the fuel injection pipe to the

2.Inspection
2.2Fuel flow method
(1)Open the fuel filter. Turn the starter switch key
to ON position.
Fuel will come from the injection pipe with
high pressure when the starter switch key is
turned to ON position if the engine is
equipped with an electric fuel pump. Direct
fuel flow into the container.
(2)Slowly turn the crankshaft clockwise,
looking at the free end of the injection
pipe. The instant fuel stops coming out is
the fuel injection timing.
Turn the crankshaft in reverse direction just
a little and do Step (2) again to verify the
injection timing.
(3)The fuel injection timing is correct if IT
mark on the crankshaft pulley is aligned
with the mark on the timing gear case
when fuel stops from the injection pipe.
