ABSTRACT:
A gear assembly is provided for use in a metal housing having a bore formed therein. The gear assembly includes a plurality of rotating gear members and at least one bushing for supporting the plurality of rotating gear members. A wear component, defined by a ring-like structure and including an opening defined therein, is provided. The plurality of rotating gear members are disposed within the opening of the wear component. The wear component is received inside of and in close tolerance with the bore. The wear component is in direct contact with the plurality of rotating gear members thereby minimizing damage to an interior surface of the bore.
