A hydrostatic transaxle with a vent assembly disposed in a port. The vent assembly may include a main fitting having a bottom member having an inner surface forming a floor and a fitting sidewall extending upwardly from the periphery to encircle the floor. A cap is secured to the sidewall and the fitting sidewall, cap and floor form a basin. A valve is disposed in the fitting sidewall. The assembly also includes cylindrical lower section extending downwardly from the bottom member to form a passage between the opening and a sump. A tower extends upwardly from the floor to the vent cap and surrounds an opening in the floor. A passage formed in the tower member to permit fluid flow between the opening and the basin.

Drive apparatus

A thrust bearing assembly is provided for the pistons of a hydrostatic drive motor. The thrust bearing assembly includes first and second retainer components removably interconnected to form a retainer assembly, a thrust bearing captured between and encompassed by the first and second retainer components, and locking tangs extending outward from the first and second retainer components. Corresponding catches are formed on the internal surface of the housing to engage the locking tangs when the thrust bearing assembly is installed in the housing.

Bearing retainer assembly for a hydrostatic transmission

A hydrostatic apparatus is disclosed. The hydrostatic apparatus comprises a pump, an input shaft, a fan and a fan shroud. The pump comprises a housing, an end cap, a first end and a second end. The input shaft extending from the first end and the second end of the pump. The fan is attached to one end of the input shaft. The fan shroud is also attached to the pump.
