6 Injection chamber
! The guide sleeve selected for an injector with a flat
nozzle retaining nut (see Fig. 73, Pos. 1) must not be
too small of too large (see Fig.74). It must be easy
to push the guide sleeve onto the nozzle retaining
nut of the injector. If the guide sleeve sticks when
it is pushed on, this means that either the injector
nozzle retaining nut or the inner surface of the guide
sleeve is very dirty or damaged. In either case, do
not use the injector or guide sleeve.
