If you would like to have your hydro rebuilt give us a call: 1-800-618-8738 or e-mail us: [email protected] We can give you an approximate cost for the hydro rebuild and help you decide if your hydro is worth rebuilding. You ship the hydrostatic transmission to us, we rebuild it, and ship it back to you, usually FedEx Ground.The hydrostatic transmission is a closed-loop circuit, where the fluid exiting from the drive motor outlet is returned to the hydrostatic pump without being sent to the tank. In this circuit, the input drive is the hydrostatic pump connected to the prime mover, and the output drive is the drive motor which is connected to the load. TypesTo push a riding mower equipped with hydrostatic drive it will be necessary to disengage the fluid drive by activating the manual bypass valve. The activation of the manual bypass valve will allow the axles to roll freely by diverting the flow of fluid around the drive pump system.The hot hydraulic oil displaced in this case from the working lines 20, 22 passes by way of the cooler 34 back into the sump 28.
