Main Drive

Assembly

Motor, flywheel, clutch-brake, and crankshaft that store and release the energy of each heading stroke; the flywheel coasts up to speed between strokes and gives up its energy through the clutch when the crankshaft drives the ram. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
