Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- Orion Bus > Orion V CNG High-floor > Orion V CNG High-floor Transit bus > CUMMINS C8.3G > C8.3G PLUS > C GAS PLUS
- Orion Bus > Orion VII CNG Low-Floor > Orion VII CNG Low-Floor Transit bus > CUMMINS C8.3G > C8.3G PLUS > C GAS PLUS
- Peterbilt > 320 > 320 Low-cab-forward truck > CUMMINS C8.3G > C8.3G PLUS > C GAS PLUS
This 4089445 turbocharger is listed for reference application on Cummins C8.3G engines, including C8.3G PLUS and C GAS PLUS variants. The supplied application clues include Orion V CNG High-floor and Orion VII CNG Low-floor transit buses, as well as Peterbilt 320 Low-cab-forward trucks. These vehicle and engine combinations serve as identification aids; buyers must verify the specific production year and configuration of their unit. Cross-check the physical turbo model code (HX40G or HX40W) against the existing assembly to confirm the correct replacement application. Do not assume universal fitment across all C8.3G applications without verifying the specific OEM reference numbers associated with your vehicle.
Technical Notes
The HX40G and HX40W designations indicate specific turbocharger configurations for the Cummins C8.3G engine. These model codes help distinguish between variants within the same engine family, which is critical for identifying the correct replacement unit. Since the input does not specify VNT, variable geometry, or oil-cooling features, do not assume these configurations are present. Buyers should verify the physical turbo model code on the existing assembly against the HX40G or HX40W identifier. This step ensures the replacement unit matches the specific application requirements for Orion buses or Peterbilt trucks. Technical fitment support is available to assist with this verification process.
