An example hydraulic pump comprises: a housing; an input shaft extending from the housing; a seal disposed within the housing and positioned about the input shaft; and a seal guard member positioned about the input shaft and mounted to the housing at an interface between the input shaft and the housing, wherein the seal guard member is configured to allow rotation of the input shaft without rotating therewith.

A carrier for a motor subassembly of a hydraulic motor is provided that enables multiple components of the motor subassembly to be temporarily bundled into a compact and easy-to-transport motor subassembly kit. The carrier is a non-hydraulically-functioning member that is configured to have one or more features that mimic a corresponding one or more features of a hydraulically-functioning motor housing to which motor subassembly is intended to be coupled for forming the hydraulic motor. The carrier may have a body with a recessed portion that is configured to receive and/or enclose one or more components of the motor subassembly, and which may cooperate with the one or more motor subassembly components to temporarily secure and bundle the motor subassembly as a compact kit, thereby facilitating transportation and handling of the subassembly components.

A pump having an endplate with an orifice provided between the system ports and the charge pump pressure cavity. Fluid flows through the orifice so as to soften a transition of the vehicle from a stationary position to a forward or reverse motion when a swash plate of the pump is angled slightly relative to a neutral or zero position.
