Abstract: A switching rocker arm comprises an outer arm having a pair of integrally formed axles extending outwardly therefrom and an inner arm pivotally secured to the outer arm. A is latch slidably connected to the outer arm and is configured to selectively extend to engage the inner arm. An inner roller is configured on the inner arm, and a pair of outer rollers is mounted on the respective integrally formed axles on the outer arm. A rocker arm for variable valve lift comprises an outer arm comprising outer arm portions, rollers mounted in a cantilevered manner to the outer arm portions, and an inner arm seated between the outer arm portions, the inner arm comprising an inner roller. A pivot axle connects the outer arm and the inner arm. The inner arm and the outer arm are pivotable with respect to one another about the pivot axle.

Abstract: A rocker arm grading system can comprise a grading tool. The grading tool can be used with a rocker arm to measure aspects of the rocker arm and determine a resulting valve lift. The grading tool can comprise a rocker arm jig comprising a pivot peg and a valve peg. A cam jig can comprise a cam arm. A cam pin can be mounted in the cam arm. A rocker arm can be removably mounted to the rocker arm jig. The rocker arm can comprise a radius on a bearing surface. A cam edge of the cam pin can press against the bearing surface. At least one measuring device comprising a wavelength emitting device paired with a wavelength detecting device can be configured to measure the radius of the bearing surface with respect to the pivot peg.

Abstract: A switching rocker arm constructed in accordance to one example of the present disclosure includes an outer arm, an inner arm, a latch, an inner roller and a first torsion spring. The outer arm has a pair of outer arm portions and a connecting arm extending therebetween. The connecting arm includes an outwardly extending tab. The inner arm is pivotally secured to the outer arm and has an outwardly extending protrusion. The latch is configured to selectively extend to engage the outwardly extending tab. The inner roller and bearing is configured on the inner arm. The first torsion spring is disposed between the outer arm and the inner arm. A first end is engaged to the connecting arm and is restrained from outward movement by the outer arm and restrained from inward movement by the outwardly extending tab. A second end is restrained by the outwardly extending protrusion.

Abstract: A switching rocker arm constructed in accordance to one example of the present disclosure includes an outer arm, an inner arm, a latch, a roller, a first lost motion spring and a second lost motion spring. The outer arm has a first outer side arm, a second outer side arm, an outer arm first end and an outer arm second end. The first outer side arm has a first leg retaining tab. The second outer side arm has a second leg retaining tab. The inner arm is pivotally secured to the outer arm and has a latch bore, a first inner side arm, a second inner side arm, an inner arm first end and an inner arm second end. The inner arm first end has a first finger, a second finer, a first hub and a second hub.
