Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

• JCB > T4.40
• KIRLOSKAR > T4.40
• Leyland > 3.8D > 3.9D > 4.0D
• PERKINS > 3.8D > 3.9D > 4.0D

This rotor assembly is listed for reference applications including JCB T4.40, Kirloskar T4.40, Perkins T4.40, Leyland 3.8D/3.9D/4.0D, and Ruston diesel systems. These application paths serve as verification clues rather than confirmed fitment data. Buyers should cross-check the part number 409172-0056 RA against their specific engine code and vehicle model. Verify the turbine and compressor wheel dimensions, shaft configuration, and bearing surfaces against your existing unit before ordering. Technical fitment support is available to assist with application confirmation.

Technical Notes

This rotor assembly is a mechanical core component, not a complete turbocharger. It consists of the turbine wheel, compressor wheel, and central shaft, which must be installed into a matching bearing housing. The visible black turbine and silver compressor wheels feature curved blade geometry designed for specific airflow requirements. Buyers should verify the shaft diameter, thrust collar position, and bearing surface condition against their existing unit. Since this part is listed for T4.40, 3.8D, 3.9D, and 4.0D applications, confirm the engine code and OEM reference numbers to ensure the rotor dimensions match your specific turbocharger housing configuration.
