The HX30W turbocharger is a complete assembly unit. Before installation, inspect the old unit for foreign object damage (FOD) such as chips or debris on the compressor wheel. If FOD is present, flush the intake and exhaust systems to protect the new part. Verify that the water cooling ports on the replacement unit match the thread pitch and diameter of your Cummins 4BTA3.9 application.
