Plus, Alliant Power Schaeffler NOx sensors have no core charge—even if the old sensor is stuck in the exhaust system.

The Cat 3406 may be a legacy engine, but it's still powering trucks and equipment across North America and South America.

When rebuilding a Cat 3406 injection pump, there are several common wear items that can impact performance—including plungers, camshafts, governor components, and transfer pump parts.

In this video, Tanner walks through what our technicians inspect during a rebuild and highlights several components available through DIPACO that help keep these pumps operating reliably.
