Key Features
- Genuine Honda OEM Sealing — manufactured to Honda's exact dimensional tolerances for the oil pump, ensuring a proper, leak-free seal where it counts most
- Direct OEM Replacement — this O-Ring installs directly into the oil pump on applicable engines with no modification required to the sealing groove or surrounding components
- Broad Fitment Across Honda's Large-Displacement Lineup — listed for GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines, as well as the EB10000 generator; verify your serial number against the fitment table to confirm the correct part for your unit
- Prevents Oil Pump Leaks — a degraded or damaged O-Ring allows oil to escape at the pump, leading to pressure loss, oil contamination of surrounding components, and potential engine damage if left unaddressed
The oil pump O-Ring forms a critical seal at the oil pump housing, preventing pressurized engine oil from escaping past the pump's mating surfaces. In Honda's large-displacement horizontal shaft engines, maintaining oil pressure is essential to keeping bearing surfaces and internal components properly lubricated under load. When this O-Ring deteriorates, shrinks, or takes a compression set, it can allow oil to seep past the pump, reducing system pressure and potentially starving engine components of the lubrication they depend on.
