Technical Notes
The TO4B11 turbocharger is a fixed-geometry unit, so installation does not require VNT vane inspection. Verify the actuator related electrical detail type and voltage rating against the John Deere 6404A harness before mounting. Confirm the turbine and compressor housings are free of debris and that the oil supply and return lines are clean. Check the gasket surfaces for damage and ensure the exhaust manifold is properly aligned to prevent stress on the turbine housing.
