Abstract: A power take-off system for an internal combustion engine that has a drive gear positioned within a crankcase includes a housing. The housing is coupleable to the internal combustion engine. The system also includes an input gear with a drive gear engagement portion, a toothed portion, and a shaft extending between the drive gear engagement portion and the toothed portion. The input gear is coupled to the housing such that the driver gear engagement portion is positioned within the crank case and the toothed portion is positioned within the housing. The input gear also includes a vent conduit that extends through the shaft. The vent conduit includes a first end open to the housing and a second end open to the crankcase.

Abstract: A quick to connect and quick to disconnect fluid coupling includes a clip, a male stem having an annular clip groove adapted to receive the clip, a female port having a step groove adapted to receive the clip upon insertion of the stem into the port, and a sleeve slideably disposed about the stem adapted to abut the clip and minimize shuttling of the stem within the port. The sleeve may be biased toward the clip by a dust seal abutting a shoulder of the sleeve distal from a lead-in end of the sleeve abutting the clip. Also, the sleeve may radially retain the clip, compressed in an annular groove of the stem, and/or the sleeve abutting the clip may stabilize the clip and axially align the clip with the stem, for insertion of the stem into the port.
