Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- CUMMINS > CUMMINS NT320
This HT3B turbocharger is listed for Cummins NT320 engine applications. The supplied application path serves as a reference clue for identification; it does not confirm universal fitment across all production years or variants. Buyers should verify the specific engine code, production year, and mounting details against their equipment before ordering. Cross-check the OEM reference numbers on your existing unit against the supplied list, including 3521551 and 3522861, to ensure the correct configuration is selected. If your application differs from the listed reference, contact technical support to confirm compatibility.
Technical Notes
The HT3B turbocharger assembly features a volute-shaped compressor housing with a straight inlet pipe and a cast iron turbine housing equipped with a two-bolt exhaust flange. A central bearing housing connects the compressor and turbine sections, secured by multiple hex bolts. The visible actuator assembly includes a related hardware arm and a threaded fitting, while a mounting bracket supports the compressor housing. A blank rectangular nameplate is present on the compressor housing. Buyers should verify the specific actuator configuration and mounting bracket orientation against their Cummins NT320 engine documentation to ensure the correct unit is selected for their application.
