Abstract
A generator includes an aluminum housing having an end plate secured to a housing portion. The housing portion and the end plate respectively include first and second bores. The end plate includes a wall with a boss providing a bore. The wall provides a lubrication passage in fluid communication with the bore. An idler gear includes a shaft having opposing first and second ends respectively supported in the first and second bores. A generator is arranged within the housing and is rotationally coupled to the idler gear. First and second impregnated carbon journal bearings respectively include a first inner and outer bearing diameter and a second inner and outer bearing diameter. The first and second outer bearing diameters are in press fit relationship with the first and second bores respectively. The inner diameters are fixed relative to their respective outer diameter.
