Abstract
An engine cranking adapter having a plurality of different pinions for selective use with any one of a plurality of different engine cranking ring gears. The adapter is mounted to a wall portion of the engine structure adjacent the periphery of the ring gear and may substitute in such mounting for the normal starter motor. The adapter is provided with structure for facilitating manual controlled rotation of the ring gear as in servicing the associated engine. The adapter may be removably mounted to a bracket which, in turn, may be removably mounted to an engine wall portion adjacent the periphery of the ring gear.

In an engine structure having a flywheel, a ring gear mounted for rotation with the flywheel, a wall adjacent the ring gear, and starter motor mounting means on said wall for mounting of a starter motor thereon to have driving engagement with the teeth of the ring gear, the improvement comprising:
- a cranking adapter having a midportion, a first pinion at one end, and a second pinion at the opposite end, said first pinion being adapted to mesh with ring gears having a first preselected configuration and said second pinion being adapted to mesh with ring gears having a second, different preselected configuration;
- adapter mounting means for readily removably, rotatably mounting said midportion of the adapter to said wall with a selected one of said pinions meshing with said ring gear;
- and
- means for transmitting a rotational force to said pinion for rotating the flywheel through the selected meshed pinion.
