Reference applications include the BelAZ 75131 mining dump truck, Komatsu 630, and Onan 1500 DFMB generator set. Buyers should verify the specific engine variant, turbo configuration, and flange type against their equipment. Cross-check OEM reference numbers such as 3594207 and 3594025 to confirm fitment before ordering. Technical fitment support is available to assist with verification.

Technical Notes

The HC5A core assembly features a central bearing housing connecting the compressor and turbine housings, with visible flanged mounting surfaces on both ends. The central shaft includes threaded ends, and a water seal or drain port is visible on the central housing. Buyers should verify the flange type and bolt pattern against their specific turbine housing application. Balancing is critical for stable operation in high-RPM engines like the Cummins KTA50; ensure the core meets balance specifications during pre-shipment inspection. Cross-check the nozzle ring vane count and height if applicable to your specific turbo configuration.
