1.2 Inspecting fuel injection timing
&$87,21
To prevent the outflow of fuel, stop the fuel supply
before removing the delivery valve.
The fuel injection timing varies with the output, speed and
other engine specifications. Be sure to check the engine's
specification sheet.
(1) Remove the No. 1 fuel injection pipe.
(2) Remove the No.1 delivery valve holder of the fuel
injection pump.
(3) Pull out the spring and delivery valve. Then do not
remove the delivery valve seat.
(4) Install the delivery valve holder.
(5) Remove the tie rod cover.
(6) Disconnect the tie rod from the control rack.
(7) Set the control rack to the medium position of the
operating range.
(8) Feed fuel from the fuel hose and check that the fuel
flows out from the delivery holder.
(9) Rotate the crankshaft forward (clockwise). The fuel
injection timing is the moment when the fuel stops
flowing from the delivery valve holder outlet.
Note: When the fuel stops flowing, rotate the crankshaft
backward (counterclockwise) to allow the fuel
flowing again. And then, rotate the crankshaft
forward (clockwise) to ensure the accurate timing
when the fuel stops flowing.
(10)It is normal that IT mark of the crankshaft pulley aligns
the mark on the gear case at the position that fuel flow
stopped.
