Hydra Service is the only Dynapower OEM supplier. We manufacture new Generation II design Dynapower units; however, we can also supply many parts for repair of the older Phase III and Phase IV designs. We offer new hydrostatic starters, pumps, motors and parts for repair. We also offer factory repairs with very fast turnaround times to keep your equipment operating. Dynapower was the largest manufacturer of hydrostatic transmissions (axial piston pumps and motors) and was headquartered in Watertown, New York. In the early 1990’s, Dynapower was purchased by Vickers and then by Eaton Corp a few years following. Throughout the changes in ownership, Hydra Service, Inc. has been building Dynapower components, repairing Dynapower hydraulics, and providing parts for Dynapower products.
