1.3 Adjusting fuel injection timing
&$87,21
When using the shim, apply sealant to both side of the
shim to prevent oil leakage.
(1) If the fuel injection timing does not meet the specified
value, increase or decrease the thickness of the fuel
injection pump adjusting shim to adjust the timing.
(adjusting value: standard value ± 1.5)
Note: A change in thickness of the shim by 0.1 mm [0.004
in.] results in a change in the fuel injection timing by
approx 1°.
(2) After adjusting, check that the fuel injection timing is
properly adjusted.
(3) Close the cock of the fuel filter, and reassemble the
delivery valve, spring, fuel injection pipe.
(4) With the delivery valve installed, check the fuel
injection timing as follows:
Note: If the fuel injection pump and the engine are dirty,
removing the delivery valve allows dirt and dust to
enter the fuel injection pump.
(5) Remove the tie rod cover and disconnect the tie rod
from the control rack.
(6) Set the control rack to the medium position in the
operating range and then remove the No. 1 fuel
injection pipe on the nozzle side. When the crankshaft
is gradually rotated forward (clockwise), fuel begins to
swell at the tip of the pipe. This timing is the fuel
injection timing. In this case, the timing is delayed by
1° as compared to the normal fuel injection timing.
