WEAR PLATE KIT FOR BRASS WATER PUMP
A wear plate kit for a 496 style/Mercruiser(R) brass water pump includes: a first wear plate to be positioned between the base assembly and the rotor; a second wear plate to be positioned between the base assembly and the upper assembly; and a third wear plate to be positioned between the rotor and the upper assembly. The wear plates repair wear to the pump caused by the rotor.
The present invention generally relates to water pumps, and more specifically, to a wear plate kit for a 496 style/Mercruiser(R) brass water pump.
SUMMARY OF THE INVENTIONIn one aspect of the present invention, a device for repairing a pump having a base assembly, a rotor, and an upper assembly includes a first wear plate to be positioned between the base assembly and the rotor; a second wear plate to be positioned between the base assembly and the upper assembly; and a third wear plate to be positioned between the rotor and the upper assembly.
In another aspect of the present invention, a device for repairing a 496 style brass water pump includes a first wear plate to be positioned between a base assembly of the water pump and a rotor of the water pump; a second wear plate to be positioned between the base assembly and an upper assembly of the water pump; and a third wear plate to be positioned between the rotor and the upper assembly; wherein the wear plates are adapted to repair wear to the pump caused by the rotor.
In yet another aspect of the present invention, a method of repairing a pump having a base assembly, a rotor, and an upper assembly includes positioning a first wear plate between the base assembly and the rotor; positioning a second wear plate between the base assembly and the upper assembly; and positioning a third wear plate between the rotor and the upper assembly; thereby repairing wear to the pump caused by the rotor.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features.
Broadly, an embodiment of the present invention generally provides a wear plate kit for 496 style Mercruiser(R) brass water pump.
An embodiment may repair surface damage on a 496/brass water pump, by installing stainless steel wear plates to damaged section of the water pump. An embodiment may replace and repair worn out surfaces on brass water pumps with stainless steel wear plates.
An embodiment may include a wear plate that may drop into the pump housing to cover up the damaged brass housing. To install an embodiment utilizing a Mercruiser(R) version 1, install a 0.047 shim, install impeller, then a gasket and then a wear plate. Apply silicon to the wear mark and bolt it back together. In an embodiment utilizing Mercruiser(R) version 2, drop a 0.024 inner wear plate into the housing, then install an impeller, an inner wear, a second impeller, a factory o-ring, an outer wear plate, an outer gasket, and a silicon the groove.
