Overview – IMP, HT3B PN00144416-0000 3519489 Series
The Cummins IMP, HT3B PN00144416-0000 3519489 fits Cummins Holset HT3B turbochargers as the impeller wheel; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
The impeller wheel (IMP) for the Holset HT3B turbocharger – the rotating element that draws in and compresses intake air, delivering the boost the engine was built around. It spins at extreme speed, so a balanced, undamaged wheel keeps the turbo from vibrating, surging and destroying itself.
Applicable Models & Applications
Used on Cummins engines fitted with the Holset HT3B turbocharger. Match the wheel to the HT3B family and its trim – impellers differ in how they flow and balance.
Maintenance & Replacement
Inspect the wheel for nicks, bends and blade erosion at every turbo service. A wheel that has taken a hit throws the balance, and an out-of-balance turbo cooks its own bearings.
Replace the wheel together with the turbo where the job calls for it. A new wheel onto a worn shaft nut still vibrates, and the vibration is what kills the centre housing.
Confirm the shaft nut is torqued and the wheel seated true before running. A wheel one step off axis destroys the seal within hours.
Keep the correct HT3B impeller wheels for your turbo on the bench. They are load-critical, and a turbo stopped on a wheel is an engine waiting on a part.
