ABSTRACT:
A water pump assembly for an internal combustion engine includes an integrated bearing and seal unit consisting of a separate bearing and seal collar in combination with a single piece stamped steel housing. The bearing collar is machined to a standard bearing bore size and a bearing is secured within the bore. The housing includes a flat mount member connected by a conical wall to an elongated tubular flange having an internal diameter slightly greater than the outer diameter of the collar and a length substantially equal to one half the collar length. The collar has an outer enlarged recessed ledge over the inner seal end which is slightly longer than the housing flange. The flange internal diameter is slightly greater than the ledge. In assembly, a plurality of brazing rings are interposed between the enlarged collar and flange, and a brazed joint is formed throughout the elongated interface between the collar and flange. The brazed housing provides the support for the bearing assembly to the engine.
