Abstract: A compressor for an air conditioning system comprises a piston and a pin. The piston comprises an aperture forming a piston bearing surface and a lubrication port in communication with the aperture. The pin comprises a pin bearing surface and the pin is received within the aperture to form an interface between the pin bearing surface and the piston bearing surface. In another embodiment, a method of lubricating within a compressor comprises rotating a crankshaft within a crankcase, introducing lubricant into the crankcase; and contacting the lubricant with a portion of a pin disposed within a piston via a lubrication port in the piston. In yet another embodiment, a piston for a compressor comprises an aperture forming a piston bearing surface and a lubrication port in communication with the aperture.

Abstract: A vehicle powerplant including an engine-transmission assembly has the engine and transmission connected together at adjacent ends and includes four mounting points. The engine has opposite sides each including one of the mounting points. The transmission includes a housing also having opposite sides and having an inspection opening in the housing adjacent the engine. A cover is secured to the housing and closes the inspection opening. The cover has two opposite supporting portions extending beyond the opposite sides of the transmission and each supporting portion includes one of the mounting points. The four mounting points are connectable with brackets for mounting the powerplant in a vehicle. Optionally, the mounting points include mounting pads on supporting ears of the transmission cover.
