Abstract: An electric cooling fan system can include a frame, a first fan, a first electric motor assembly supported by the frame and operably connected to the first fan, a second fan, a second electric motor assembly supported by the frame and operably connected to the second fan, and a liquid cooling path that passes adjacent to both a first stator of the first electric motor assembly and a second stator of the second electric motor assembly such that thermal energy is transferable from the first electric motor assembly and the second electric motor assembly to a liquid coolant present in the liquid cooling path. Other aspects of an electric cooling fan system and associated method of making the same are also disclosed.

Abstract: A clutch assembly includes a stationary journal bracket assembly having a base, a stub shaft that extends axially from the base, and a passage, a threaded bracket journal coupled to the stub shaft and accessible through the passage, pulley bearings supported on the threaded bracket journal, an integrated pulley/shaft including a pulley and a center shaft, and a clutch mechanism. The center shaft includes a cup-like hub and a distal portion that extends axially from the cup-like hub. The cup-like hub is supported on the pulley bearings, located at least partially within a blind hollow interior area of the cup-like hub. The threaded bracket journal is located at least partially within the hollow interior area of the cup-like hub.
