debris from the bearing surface 72 and 73 are oil containment puddles for additional and early lubrication groove 74 34 brings back 34 oil to further lubricate the bearing 67c without 72 and 73 or 70 and 74 too much oil would be removed by 70 and the bearing would blister and fail the bottom side position of grooves 72 and 73 also features new grooving that does not extend to either edge of the rear main bearing 7 this prevents oil drainage from the bearing surface 56d when the internal combustion engine 1 is not running this containment of oil on the bearing surface 56d establishes a permanent 34 reservoir 34 of oil to exist for 34 cold 34 start up protection which oil activates onto the bearing surface 56d as soon as the crankshaft 2 begins to turn these 34 reservoirs 34 introduce the oil much quicker to each of the bearing surfaces 56a d of bearings 3 4 5 6 and 7 during the 34 cold start 34 phase of the internal combustion engine 1 after sitting cold when an internal combustion engine 1 is first started up it takes a moment for the oil to circulate around the bearing surface all the way from the top in the meantime the crankshaft 2 is turning momentarily on a 34 dry 34 surface which detriment is now eliminated by the present invention the result is extended internal combustion engine life reduced internal combustion engine 34 drag 34 and also reduced bearing 34 spin 34 from its seat these reservoirs also act.
