Technical Notes

The TO4B91 turbocharger is a fixed-geometry unit designed for Caterpillar 3304T 7000CC engines. Unlike variable-geometry turbos, it uses a static turbine wheel, which is typical for this engine class. Buyers should verify the specific turbo configuration on their unit, as production years may vary. Check the turbine housing and compressor housing for any unique markings or modifications. Confirm the thrust bearing type and load capacity match your application requirements. For systems with bypass valves, ensure the valve operation aligns with the turbo's design. Technical fitment support is available to assist with these verification steps before ordering.
