Well 777Funk, you have a very unique engine
starting with the unit injectors.... the injector and the pump
are a single
unit operated by dedicated lobes on the overhead cam the same as a Detroit diesel
, really difficult to adjust and troubleshoot. The belt driven cam adds a new level of difficulty to routine maintenance
as it has a "remove and replace belt" requirement at
hours and has the threat of an engine
damaging incident if that belt ever breaks.
These engines were fitted to AC gen sets as well as being propulsion
units and were remarkably susceptible to problems caused by dirty fuel
so only use 2 micron filters and change them often.
Get a copy of the service
manual and some of the special tools needed to change/adjust injectors and learn how to swap out the timing belt because even the Lombardini dealers find these engines a bit of a challenge.
