A variable speed drive includes a transmission in a housing with a rotatable control shaft for moving the transmission between neutral and drive positions. A rotary damper is engaged to an external control arm which rotates the control shaft. A return to neutral mechanism is engaged to the control shaft to return the transmission to neutral. The external damper may be a viscous fluid damper having a plate, a rotor element with a first set of concentric projections, and a stator element with a second set of concentric projections that mesh with the first set of concentric projections. A method is provided for assembling a damper subassembly and a return arm subassembly, and connecting the damper subassembly to the housing, connecting the control arm to the control shaft and connecting the return arm subassembly to the control shaft for ease of assembly. |
