- release nuts 2 for fixing the fuel pump drive gear to the drive half coupling for
1…1,5 revolutions;
- remove part of fuel from the ignition tester glass pipe if there is such;
- by means of a key turn the fuel pump spindle behind nut 4 to both sides within the
grooves located on the butt end of the fuel pump drive gear until the ignition tester glass
pipe is filled with fuel;
- set the fuel pump spindle into the extreme (contraclockwise) position within the
grooves;
- remove part of fuel from the glass pipe;
- slowly turn the fuel pump spindle clockwise, at the moment when fuel starts to up-
lift in the glass pipe stop rotating the spindle and tighten the nuts for fixing drive gears to
the drive half coupling;
- carry out the repeated check of the fuel supply start moment;
