SERIES 40 ENGINE OPERATOR'S GUIDE GENERAL INFORMATION Engine Features The Series 40 is a family of inline six-cylinder, 4-stroke cycle, water-cooled, turbocharged engines which may be equipped with a chassis-mounted, air-to-air charge cooler system. Engines built prior to 1998 used a mechanical, high-pressure fuel pump and individual injector nozzles. Operators of these engines should refer to Series 40 Engine Operators Guide 6SE516 for preventive maintenance information. Engines built from 1998 – present are direct fuel injected with hydraulically actuated, electronically controlled unit injectors. This operator's guide covers these current engines.
