Cummins QST30 Engine Overivew
QST30 FOR CONSTRUCTION (TIER 2)
Cummins QST30 powers the biggest construction equipment and tackles the biggest jobs. For years, it's delivered exceptional performance and durability with low maintenance and operating costs.
Available in ratings from 760-1200 hp (567-895 kW), the QST30 uses advanced electronics and robust standard features for superior reliability and durability.
Every QST30 engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest plans of the industry.
The QST30 delivers more power and more torque in a smaller package than competitive diesels. Known for its flexible calibrations, excellent power density, economical operation and exceptional uptime, the QST30 sets the standard for rugged dependable power. Every day. Every week. Every year.
The QST30 is an excellent choice to replace a number of engines - including some of our own. It has significantly more power, as much as 50% longer life-to-rebuild and better fuel economy than the Cummins V28, even though it is virtually the same size. Repowers are available with air-to-air cooling (for equipment which has to meet emissions standards) or jacket-water aftercooling (for non-emissionized equipment).
If you have an older competitive engine, you'll find that replacing it with the QST30 gives you up to 25% more power and torque, better fuel economy and longer service intervals, for increased productivity with lower costs. Every time.
