The Honda 15140-ZA0-980 Oil Pump Gear Assembly (45T) is a genuine OEM component designed for EV4010, EV6010, and EVD4010 RV generators and the GX360 horizontal shaft engine. As a direct OEM replacement, this assembly is manufactured to Honda's exact specifications, ensuring the oil pump operates as Honda originally engineered it. Verify your model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct assembly must match your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this assembly carries the same tooth count and dimensional tolerances as the original, ensuring the oil pump meshes and drives correctly without adjustment.
- 45-Tooth Specification — the (45T) designation identifies the exact variant; confirm this matches the gear your unit requires before installing, particularly if multiple gear configurations exist across the model range.
- Broad Fitment — covers the EV4010, EV6010, and EVD4010 RV generators and the GX360 engine; check your serial number against the fitment table to confirm this is the right assembly for your serial range.
- Protects Against Oil Starvation — a worn or damaged oil pump gear reduces oil pressure and flow, risking accelerated wear or engine damage; replacing it restores proper lubrication throughout the engine.
The oil pump gear assembly transfers rotational drive from the engine's crankshaft to the oil pump, keeping lubricating oil circulating through the engine under pressure. When the gear teeth wear or the assembly fails, oil pressure drops — leading to increased friction, elevated operating temperatures, and potential engine damage. Replacing this assembly with the correct genuine OEM part restores the oil pump's ability to deliver consistent pressure and flow, protecting internal engine components throughout the service life of the machine.
