Claim:
A method for coupling a valve cover to a pump assembly, the method comprising: securing a first cylindrical member to the pump assembly, wherein the first cylindrical member has a central axis and an axially extending throughbore; circumferentially aligning a set of interlocking lugs on a radially outer surface of a second cylindrical member between two adjacent sets of interlocking lugs on a radially inner surface of the first cylindrical member; axially inserting the second cylindrical member into the throughbore of the first cylindrical member; rotating the second cylindrical member about the central axis relative to the first cylindrical member to engage the set of interlocking lugs on the second cylindrical member with one of the sets of interlocking lugs on the first cylindrical member after inserting the second cylindrical member into the throughbore of the first cylindrical member; axially inserting a stop locator into a void formed radially between the first and the second cylindrical members and circumferentially between the two adjacent sets of interlocking lugs on the radially inner surface of the first cylindrical member after engaging the set of interlocking lugs on the second cylindrical member with one of the sets of interlocking lugs on the first cylindrical member.
