Every™ Part. Genuine.

Cummins Westport is the industry’s leading producer of natural gas fueled engines. One of the reasons for this success is the engine build strategy – using many common parts from Cummins diesel engines as the foundation, with support through the largest and most capable parts and service network in the world.

Over 80% of the major components in the ISX12 G natural gas engine are exactly the same as their diesel counterpart. This has several advantages.

First, diesel engines are built with robust components to withstand the higher combustion pressures – so they naturally last longer. Second, using the same high-volume parts across both diesel and natural gas platforms lowers the cost of the part and improves availability. Third, having similar components – including the electronic control systems that govern engine and aftertreatment performance – makes it easier for service technicians to maintain these engines.

These components include: � Engine Block � Crankshaft � Camshaft � Connecting Rods � Cylinder Liner � Main Bearings � Bushings

These parts are built to withstand a compression ratio of 16.6:1, so they can easily handle the 12:1 compression ratio in a natural gas spark-ignited engine. Although some parts are unique to natural gas engines, every Cummins Westport natural gas engine part is readily available through the Cummins authorized parts and service network.

With the growing volume of Cummins Westport natural gas engines in the field, parts manufacturers have started offering non-genuine substitutes, particularly on high-volume diesel components. There is a significant difference in Genuine Cummins parts versus non-genuine parts. Close examination shows differences in materials, overall design and machining on these critical parts – quality differences that can lead to premature wear, reduced fuel economy and increased risk of engine failure.
