Non-genuine part inspection results
| Part tested | Dimensional testing | Material testing |
|---|---|---|
| Piston | FAILED | FAILED |

Of the over 300 non-genuine parts tested, none met all of Cummins Design Specifications, and most failed in both the dimensional and material testing categories. Test results marked as “adequate” marginally met Cummins design intent, indicating that it loosely met some of Cummins design specifications, but not all of them.
Saving a little time upfront could ultimately cost you:
Early life failure
Additional fuel cost
Downtime
Progressive damage to aftertreatment
Non-warranty repair cost
Catastrophic failure
