LOMBARDINI CONTINUALLY DEVELOPS THE FOCS DIESEL LINE. CONSTANT RESEARCH AND DEVELOPMENT IS CARRIED OUT TO
IMPROVE OVERALL PERFORMANCE OF FOCS PRODUCTS. AS SUCH, THE DESIGN OF THE FOCS UNIT INJECTOR HAS CHANGED
DURING THE DEVELOPMENT PROCESS. THE FIGURE ABOVE PROVIDES A REFERENCE FOR THE THREE(3) DIFFERENT VERSIONS
OF THE FOCS UNIT INJECTOR TO DATE.
EARLY UNIT INJECTORS ARE CHARACTERIZED BY THE HIGH PRESSURE PORT AS SHOWN.
INTERMEDIATE UNIT INJECTORS ARE CHARACTERIZED BY THE LACK OF A DRILLED HIGH PRESSURE PORT (HIGH PRESSURE
PLUG MAY BE PRESENT, BUT IS NOT FUNCTIONAL) AND THE ADDITIONAL INDEX PIN AS SHOWN.
CURRENT UNIT INJECTORS ARE CHARACTERIZED BY OFFSET FUEL PORTS, NO HIGH PRESSURE PORT AND RELATIVELY LARGER
PORT SIZES.
THE FOLLOWING CHART MAY BE USED AS A GENERAL REFERENCE FOR UNIT INJECTOR IDENTIFICATION, SPECIAL TOOL
REQUIREMENTS AND CRITICAL ADJUSTMENT SPECIFICATIONS. WHEN SERVICING FOCS UNIT INJECTORS, ALWAYS REFERENCE
THE ENGINE MODEL, ENGINE SERIAL NUMBER, APPLICATION AND UNIT INJECTOR REFERENCE NUMBER.
