4. The injection pump – of Bosch make, must not be dealt or tampered with by
anyone other than an authorised BMW Marine Engine or Bosch diesel dealer.
Should the pump need to be removed, it is very important that all openings, fuel
line connectors, etc are properly sealed to prevent contamination.
5. The injector – of Bosch manufacture, will normally need no maintenance except
for cleaning of the area nect to the atomizer. The injector must not be dismantled,
since the set injection pressure then could be altered inadvertedly.
WARNING – when the injector is tested outside the cylinder, the jet must not
be directed towards unprotected skin, eyes, etc as it is powerful enough to
penetrate the skin, causing nasty wounds and possible infection.
When installing the injector, make sure that the cylinder head seal is clean and
the nuts evenly tightened to 1.0 kpm (7.2 lb.ft.)
