TESTING AND ADJUSTMENTS - CONTROL AND ADJUSTMENT OF THE INJECTION TIMING
CONTROL AND ADJUSTMENT OF THE INJECTION TIMING
★ Check the injection timing of the No.1 cylinder by means of the No.1 union of the injection pump.
★ The cylinders are numbered 1-2-3-4 counting from the flywheel side.
★ The spark advance notches of 0°-10°-15°-20°; are also marked on the flywheel. In order to read the intermediate values, sub-divide the sections between the two marks into equal lengths.
1 - Remove the cap (1) of the flywheel casing.
2 - Pass a screwdriver between the teeth and rotate the flywheel in a counter-clockwise direction (as seen from the flywheel side) until the 1/4 notch of the flywheel is aligned with the notch (2) marked inside the hole in the casing.
★ In this position, the piston of the No. 1 cylinder is at the top dead centre (B.T.D.C.). Check that the cylinder is in a compression stroke, i.e. that both valves are closed.
★ Once the B.T.D.C. has been ascertained, rotate the drive shaft in a clockwise direction (seen from the flywheel side) for about 25 teeth.
3 - Take off the clamp (3) and disconnect all the fuel delivery pipes (4) from the injection pump (5).
4 - Rotate the flywheel slowly in a counter-clockwise direction (seen from the flywheel side), checking carefully the level of the fuel in the No. 1 union of the injection pump.
Stop the rotation when the fuel level starts to rise.
5 - Check the position of the notches at 15° and 10° that appear in the hole in the casing and, in function of the position, establish the true fuel injection timing.
★ In order to determine the degrees of intermediate fuel injection timing, sub-divide the space between 10° and 15°.
★ Normal fuel injection timing: 12±1°
