    Abstract: A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly comprises a tappet body defining a pair of apertures and at least one seat, and a follower assembly. The follower assembly has a shaft, a first bearing, and a second bearing, each supported on the shaft for engaging the camshaft lobe. An intermediate element is further supported on the shaft between the first and second bearings and has a platform for engaging the fuel pump assembly. The intermediate element is at least partially disposed in the at least one seat of the tappet body and the shaft is disposed in the pair of apertures of the tappet body.

    Abstract: A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly includes a bearing assembly having a shaft and a bearing rotatably supported by the shaft for engaging the lobe. An intermediate element has a shelf for engaging the fuel pump assembly, and a pair of arc-shaped bearing surfaces rotatably engaging the shaft when the bearing engages the lobe and the shelf engages the fuel pump assembly. The intermediate element includes a pair of lock apertures. The bearing assembly further includes a pair of shields supported on the shaft of the bearing assembly with the bearing interposed between the shields. The shields include a pair of opposing fingers for engaging the lock apertures so as to substantially retain the bearing assembly to the intermediate element and so as to substantially retain the shaft of the bearing assembly within the annular body in absence of engagement between the bearing and the camshaft lobe.

The tappet assembly includes a bearing assembly having a shaft and a bearing rotatably supported by the shaft for engaging the lobe. An intermediate element has a first aperture, a shelf for engaging the fuel pump assembly, and a pair of arc-shaped bearing surfaces rotatably engaging the shaft when the bearing engages the lobe and the shelf engages the fuel pump assembly. An annular body has a second aperture and at least one stop member abutting the intermediate element to align the first aperture with the second aperture. An anti-rotation clip is disposed so as to extend through the apertures and cooperates with the stop member to substantially prevent rotational and axial movement of the intermediate element with respect to the body.

    Abstract: A locator for use in a valvetrain of a cylinder head of an internal combustion engine having a valve substantially concentrically aligned with both a valve spring and a support, the support at least partially extending into the valve spring. The locator includes an annulus seat that supports the valve spring. The locator further includes a tapered ring operatively attached to the seat that has a tapered inner surface, for at least partially accommodating the support of the valvetrain therein, and a tapered outer surface, for at least partially engaging and concentrically aligning with the valve spring. The locator also includes a plurality of radially-spaced lobes. The lobes are disposed on the inner surface of the ring and at least partially engage the support such that the locator substantially concentrically aligns the valve spring with the valve and the support.

    Abstract: A retention device for a valve actuating mechanism to secure a finger follower and lash adjuster together includes a ring member disposed in a groove of a movable piston of the lash adjuster. The retention device also includes a connecting member having a plurality of legs adapted to engage the finger follower and an intermediate base interconnecting the legs and adapted to be disposed below the ring member and about a portion of the lash adjuster to effect a free movement of the connecting member in all pivoted positions of the finger follower.
