A pump impeller assembly comprises a pump journal, an impeller fixed to one end of the pump journal, and a pulley fixed to the other end of the pump journal. The pump impeller assembly further comprises a pump bearing including an outer race surrounding the pump journal with the pump journal being adapted to rotate with respect to the outer race. The pump impeller assembly includes a support plate fixed to the outer race and lying in a radial plane with respect to the pump journal. The support plate has a plurality of locking tabs adjoining its peripheral edge. The locking tabs are circumferentially spaced apart from one another with respect to the pump journal. The locking tabs are adapted to interlock with locking lugs formed on the inner surface of a pump housing wherein the locking lugs are adjacent to a pulley opening in the pump housing through which the pulley extends and are circumferentially spaced apart from one another with respect to the pulley opening. The locking tabs are adapted so that the interlocking enables secure attachment of the support plate to the pump housing.

Pump impeller assembly

A drip collector installed to a vehicle coolant pump of the type that has a protruding cylindrical bearing race with vent holes includes a feature to prevent collected coolant from splashing out, but not preventing it from collecting in the first instance. The collector includes at least one axially extending cylindrical sleeve that overlays the vent hole, with a small radial gap from the outside of the bearing race. Leaking coolant can run slowly through the gap, but cannot splash out quickly.

Coolant pump drip collector with splash control

A channel type vehicle water pump drip collector provides improved efficiency and capacity and a simple installation. The internal volume enclosed by a retainer that is snap fitted onto the housing is filled with an absorbent material. Leaking coolant is soaked up, rather than puddling at the bottom of the channel. Therefore, a leak proof, welded connection is not needed. In the embodiment disclosed, a retainer for the ring is attached by flexible teeth, and the spaces between the teeth provide air vents through which absorbed coolant may gradually evaporate to the outside.

Coolant pump drip collector with improved capacity

A slinger ring for a vehicle water pump shaft is given a scalloped outer lip, which causes the lip to undulate back and forth past vent holes in the bearing race as the pump shaft rotates. This provides a continual vent hole cleaning and scraping action.
