Cummins Inc. (NYSE: CMI) and Isuzu Motors Limited (hereinafter “Isuzu”), a leading global truck manufacturer headquartered in Japan, are launching a new 6.7-liter engine jointly developed by the two companies, designed for use in Isuzu’s new medium-duty truck lineup. The “Isuzu DB6A” will power on-highway truck applications built for the Japanese market and will be available for the Asia Pacific markets and other global markets later this year. The engine will be assembled at Isuzu’s engine plant in Tochigi Prefecture, Japan.

To rebuild engines, mechanics remove them from the car to disassemble the unit, inspect its components, and clean the parts. The auto shop may reuse serviceable moving parts and replace broken or worn-out ones. But most experts advise against this type of engine reconditioning unless it’s relatively new and you’re confident the engine needs only a few specific replacement parts to fix the current problem.

A remanufactured engine is a more extensive machining job than rebuilding, because the engine is pulled out of the vehicle and returned to factory conditions and blueprint specifics. Everything that has any potential wear is replaced to bring the engine back to its original standards. Anything that isn’t replaced is remanufactured to the standards of a new part.
