Technical Notes

This turbocharger assembly is designed for heavy-duty CAT 3408 engines, requiring careful inspection of physical dimensions before installation. Buyers should verify the compressor and turbine housing flange bolt patterns match their existing unit. Check oil inlet and outlet port sizes to ensure proper lubrication flow. Confirm the exhaust manifold connection type aligns with your engine configuration. Since variations exist across CAT 322D and Peterbilt 359 applications, visual comparison of the mounting bracket and actuator related hardware is recommended.
