10.9 Demounting and remounting
Loosen the ring nut that fixes the nozzle using a torque wrench
and as device like the one shown in fig. 42 which relieves the
pressure exercised by the spring on the ring nut.

Visual inspection:
Visual inspection: make sure that the needle housing is
not deformed or excessively rough.
The nozzle body must not show signs of wear or damage.
The holes must be free from carbon residues.
2) Smoothness test

Smoothness test
Smoothness test: the nozzle needle, which will have
been previously immersed in impurity-free fuel, should be
inserted into the body of the nozzle. Noz extract it by up to
a third of the guide length, holding the nozzle in a vertical
position. The needle must drop back into its housing
thanks to its actual weight alone.
Remount the injection in compliance with the order indicated
in fig. 39. Make sure that the plugs and centering pins on the
spacer (N° 8 fig. 39) match the relative holes in the housings.
Tighten the ring nut that fixes the nozzle to a value of:

below the injection pressure value. Release the lever and
check the time it takes to drop. The pressure must drop to 150
to 100 Kg/cm² withinn 6 to 40 seconds.
- replace the nozzle if it drops in less than 6 seconds.
- if it takes longer than 40 seconds to drop, make sure that
there are no carbon deposits in the nozzle and that the
return holes are not clogged.
