Gear cover and gear housing system

A system for an internal combustion engine, the system comprising:

• the gear housing assembly including:
• a gear housing including a rear face configured for assembly to a block of the internal combustion engine, the gear housing including a front face opposite the rear face, and the gear housing including a plurality of gear housing drillings;
• a gear cover including a rear face for attachment to the front face of the gear housing to form a gasketed interface between the gear housing and the gear cover, the gear cover including a front face opposite the rear face of the gear cover, the gear cover including a plurality of gear cover drillings, wherein the gear cover is attached to the gear housing such that the plurality of gear cover drillings is fluidly connected with the plurality of gear housing drillings via the gasketed interface between the gear housing front face and the gear cover rear face;
• a debris screen in one of the plurality of gear cover drillings, the debris screen configured to trap debris in oil flowing through the plurality of gear cover drillings before the oil passes to the plurality of gear housing drillings;
• and
• an access cover mounted on the gear cover, wherein the access cover is removable from the gear cover;
• and
• an idler gear positioned between the access cover and the gear housing, the idler gear is accessible when the access cover is removed from the gear cover.
