Switchable rocker arms assemblies and methods thereof

A method of making a rocker arm assembly, comprising:

• constraining a first body and a second body of the rocker arm assembly together in an assembled configuration, wherein at least one of the first body or the second body is rotatable about a rocker shaft, and wherein the first body and the second body are operatively coupled during operation;
• providing, while the rocker arm assembly is constrained in the assembled configuration, a latch bore passing through each of the first body and the second body so that a latch assembly is operable in a first latch state to operatively couple the first body and the second body to prevent relative motion therebetween and the latch assembly is operable in a second latch state to permit relative motion between the first body and the second body, wherein the latch assembly of the rocker arm assembly comprises the latch bore;
• providing, while the rocker arm assembly is constrained in the assembled configuration, a stop bore passing through each of the first body and the second body, wherein a stop mechanism of the rocker arm assembly comprises the stop bore and a stop pin;
• and
• disposing the stop pin in the stop bore and coupling the stop pin to one of the first body or the second body so that the stop mechanism operatively constrains a range of the relative motion between the first body and the second body associated with the second latch state of the latch assembly.

• providing, while the rocker arm assembly is constrained in the assembled configuration, a stop bore passing through each of the first body and the second body, wherein a stop mechanism of the rocker arm assembly comprises the stop bore and a stop pin, and wherein the stop bore includes a conforming portion associated with the second body such that a radius of curvature of the conforming portion is configured to receive the stop pin;
• disposing the stop pin in the stop bore and coupling the stop pin to the first body so that the stop mechanism defines a range of relative motion between the first body and the second body;
• and
• providing a clearance cut overlapping with at least a portion of the stop bore in the second body, wherein one or more edges of the clearance cut define a limit of allowable travel of the stop pin coupled to the first body during operation of the rocker arm assembly.
