– Check the spray pattern of the injector
as shown in Fig. 130.
Assembling:
– Install the injectors using new sealing
rings and working in the reverse order
for their removal.
Note:
– Place the seal on the injector so that
the soft graphited side is at the top
towards the injector.
– Tighten the hex nuts to retain the injec-
tor and the collar nuts on the pressure
pipe to the specified torques (see Sec-
tion 4), holding the pressure pipe con-
nection on the injection pump to prevent
it from turning.
– The fuel pressure pipes from 2 L 40.17,
3/4 L 40.16, M 40 L.13 and M 31 L
have a smaller internal diameter and
are identified by the section of hose
pushed on to them.
