Every day, QSM engines are put to the test in construction equipment worldwide with superior performance.

Maintenance is kept to an absolute minimum, with oil change intervals that are double the previous standards in some applications, sealed sensors and an auto-tensioning belt drive.

Available in a range of ratings from 250-400 hp (186-298 kW), every QSM is perfectly matched to every piece of equipment.  The QSM not only meets Tier 2 and Euro Stage II emission standards, its advanced design can reach Tier 3 and Stage IIIA requirements as well, with minimal changes.  Cummins engineers work with the original equipment manufacturers, shaping power curves and ratings to align with the work environment, load factors and operating modes.  Then, we optimize the engine’s performance with the other vehicle components and subsystems, using Cummins Advisor.

The QSM come with virually every feature standard.  QSM options include REPTO (Rear Engine Power Take-Off).

Every QSM engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest plans in the industry.
