Buyers should inspect the shaft journal surfaces for wear or scoring before assembly. Confirm that the oil and water connection ports are free of debris and that O-ring grooves are intact to prevent leaks during installation. Verify the compressor wheel nut thread direction and tightening torque specifications against the service manual for your specific engine.
