| Tornado Restorers Jerry Abbamont (left) and Kenny Bell stand beside the Tornado during restoration. | Front Section Being Prepared for Painting. The engine is upside down in this image. At the nose case top is a mounting pad for the fore oil scavenge pump; at the left is the propeller governor mounting pad. The remaining pads are covers for other accessory drives. | Two Mounting Pad Circles Aft of the Nose Case. The triangular fore ones are for the seven magnetos; the larger ones aft are camshaft drive gear covers. | One of the magneto drives (above right of the image center) has not yet been masked. The drive shaft and three threaded holes for mounting bolts are visible. |

| In this view of the vee between cylinder banks, the masked-off exhaust flange is visible along one wall (top), and intake ports are visible on the other (bottom). The large aft hole leads to the supercharger. Spark plugs, ignition harness, cooling air blast tubes, an intake manifold and an exhaust manifold, along with their attaching hardware, had to be fitted into this very tight space. This same scheme was used for all seven cylinder banks. | Camshaft, Rocker Arms, and Valves for Two Cylinders. Each of the 84 valves had to be adjusted manually, which required removal and replacement of 7 valve covers, each with 50 lock-wired fasteners and a gasket. | The rear accessory case has been removed, exposing the supercharger impeller. | Supercharger impeller and passages to the seven intake manifolds. |
