Abstract: A system comprises a follower lever and a follower roller rotatably coupled to the follower lever. A pin is rotatably coupled to the follower roller, the pin comprising a first outer portion including a first diameter and a second outer portion including a second diameter. A central portion is positioned between the first outer portion and the second outer portion, the central portion including a third diameter, the third diameter being smaller than the first diameter and the second diameter. One or more first channels is defined by the first outer portion, the one or more first channels positioned within the first outer portion and configured to direct fluid away from the central portion as the pin rotates.

Abstract: A gear housing assembly includes a gear housing and a gear cover for an internal combustion engine. The gear housing includes gear housing drillings, the gear cover includes gear cover drillings, wherein the gear cover is attached to the gear housing such that one of the gear cover drillings is fluidly connected with one of the gear housing drillings via a gasketed interface to supply oil through a debris screen to two fuel pumps mounted on the gear housing. A serviceable access cover is mounted on the gear cover. An idler gear is assembled onto an idler shaft to form a sub-assembly, wherein the idler gear is positioned between the serviceable access cover and the gear housing. The idler shaft is supported by the bushing in the access cover and two bushings mounted in the gear housing to provide radial and thrust load bearing capabilities.
