Abstract

A hydrostatic assembly includes a pump having a yoke and an associated rotating group. The pump yoke has a bucket portion and an arm portion. At least one fluid passage extends through the pump yoke. The hydrostatic assembly also includes a motor having a yoke and an associated rotating group. The motor yoke also has a bucket portion and an arm portion. At least one fluid passage extends through the motor yoke. The arm portion of the pump yoke and the arm portion of the motor yoke have associated coupling portions for fluidly coupling the pump yoke to the motor yoke so that the at least one fluid passage in the pump yoke is in direct fluid communication with the at least one fluid passage in the motor yoke.
