A sealed compressor has a lower end cap secured to a center shell, and defines a sealed chamber. An electric motor is received within the sealed chamber. The electric motor drives a shaft that drives a compressor pump unit. A lower bearing housing includes a bearing for supporting the shaft, and an oil pump. The oil pump includes a pump housing including one of a slot and a leg, with the bearing housing including the other of a slot and a leg. The leg is received in the slot to position the pump housing within the bearing housing. The oil pump further includes a piston to be driven by the shaft to drive the lubricant from a sump in the sealed chamber upwardly into a passage in the shaft.
