A reciprocating lever for a valve train assembly is provided, including a receiving portion and at least one retaining feature. The receiving portion is for selectively receiving a member that is actuated by the reciprocating lever. An actuation direction is also included and is defined by an actuation axis, wherein the reciprocating lever selectively actuates the member. The at least one retaining feature is located at the receiving portion of the reciprocating lever. The at least one retaining feature is configured to selectively engage with and limit relative movement of the member with respect to the reciprocating lever along the actuation axis.

A rocker arm for engaging a cam is disclosed. An outer arm and inner arm are configured to transfer motion to a valve of an internal combustion engine. A latching mechanism includes a latch, sleeve and orientation member. The sleeve engages the latch and a bore in the inner arm, and also provides an opening for an orientation member used in providing the correct orientation for the latch with respect to the sleeve and the inner arm. The sleeve, latch and inner arm have reference marks used to determine the optimal orientation for the latch.

A method of precision manufacture of an outer arm of a rocker arm assembly is performed by determining structures of a rough outer arm that would require precision processing and locations to support the structures as they are processed. Starting with at least one structure requiring precision processing, locations on the outer arm close to the structure to hold the outer arm during processing are determined that would cause minimal distortion of the outer arm during processing. The outer arm is then provided with clamping lobes at these locations. The clamping lobes of the outer arm are clamping into a fixture for manufacturing. The slider pad may now be precision ground while the outer arm is clamped in the fixture with minimal risk of distortion of the outer arm.

A switching rocker arm having an outer arm having a first end, a second end, a first and second outer side arm having slider pads that ride on a second cam is disclosed. The switching rocker arm also has an inner arm disposed between the first and second outer side arms. The inner arm has a first end, a second end and a bearing disposed between the first and second end adapted to ride along a first cam. The inner arm is pivotably secured adjacent its first end to the outer arm adjacent its first end. At least one arm has an over-travel limiter structure limits pivoting motion of the first arm relative to the second arm. The switching rocker arm also exhibits decreased lash as the bearing wears, and increased lash as the latch and slider pads wear.

A hydraulic capsule can comprise a hollow capsule body for setting the location of a plunger, a latch set alignable with a latch groove, and a latch-setting insert. The plunger can be configured to push the latch set towards the latch-setting insert. A lost motion spring can be incorporated into the hydraulic capsule, or the lost motion spring can be installed in capsule bore where the hydraulic capsule is mounted. Either a hydraulic capsule or an electromagnetic capsule or a drop in assembly can be installed in a capsule mount in a rocker arm to form a type III cam-actuated rocker arm. The rocker arm can comprise a cam side arm and a valve side arm. The rocker arm can be configured to balance a moment of inertia of the deactivation components. Twisting forces on the cam can be counteracted.
