This engine is a perfect match for the Hoover FH50150. But it was shipped and packaged in AIRplus air bubble. Upon arrival, all air pockets are flattened out due to the shape of the edge of the engine, and the entire engine was like a rock bouncing around in a box. So this is a very bad way of delivering this product in this form. While it fits and works fine on day 1, I'm not sure the product went bad during such a delivery.
