Abstract: A method for setting lash on a switching rocker arm assembly includes providing a rocker arm having (i) an outer arm having a first outer side arm and a second outer side arm, the outer arm defining an opening, (ii) an inner arm disposed between the first and second outer side arms, (iii) a roller follower that selectively engages a cam, the roller follower mounted about a bearing axle that extends through the opening. A zero lash shim is inserted into a gap defined between the bearing axle and the outer arm at the opening. The rocker arm is installed into the valvetrain with the master tip cap. Lash is measured between the cam and the roller follower. The rocker arm and the master tip cap is removed. A select fit valve tip cap is installed based on the master tip cap and the measured lash.

Abstract: A switching rocker arm assembly can include an outer arm, an inner arm and a latch assembly. The outer arm can have one or more high lift lobe contacting surfaces, where each of the high lift lobe contacting surfaces has an uppermost point that defines an outer arm tangent plane. The inner arm can be pivotably secured to the outer arm and have a low lift lobe contacting surface. The low lift lobe contacting surface can have an uppermost point that defines an inner arm tangent plane that is parallel to the outer arm tangent plane. The inner arm tangent plane can be spaced from the outer arm tangent plane by a minimum distance. The latch assembly can be movable between a first configuration in which the outer arm rotates with the inner arm, and a second configuration in which the outer arm rotates independently from the inner arm.

Abstract: A switching rocker arm assembly can include an outer arm having a first outer side arm and a second outer side arm, each of the first and second outer side arms having a high lift lobe contacting surface, and an inner arm disposed between the first and second outer side arms and pivotably secured to the outer arm, the inner arm having a low lift lobe contacting surface and defining a latch bore. A latch assembly can be arranged at least partially within the latch bore of the inner arm. The latch assembly can include a latch pin having an orientation pin receiving recess, a sleeve engaging the latch pin and having an orientation pin opening, and an orientation pin extending through the orientation pin opening into the orientation pin receiving recess.

Abstract: A switching rocker arm assembly constructed in accordance to one example of the present disclosure can include an outer arm, an inner arm, a pivot axle, a bearing axle, a first torsional bearing axle spring and a second torsional bearing axle spring. The outer arm can have a first outer side arm and a second outer side arm. The outer arm can further include first and second torsional spring mounts. The inner arm can be disposed between the first and second outer side arms. The pivot axle can support the inner and outer arm for relative pivotal movement therearound. The bearing axle can support a bearing. The first torsional bearing axle spring can be mounted around the first torsional spring mount and have a first end engaged to the bearing axle and a second end engaged to the outer arm. The first end extends inboard relative to the second end.
