The Honda 15339-ZJ4-000 Oil Plate O-Ring is a genuine OEM replacement designed for GXV610, GXV620, and GXV670 vertical shaft engines, as well as HA4118 and HA4120 lawn tractors and HRC7018 and HRC7020 commercial mowers. As a factory-sourced component, this O-Ring is manufactured to Honda's exact dimensions and material specifications, ensuring a proper seal where it matters most. Confirm your machine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at serial number breaks.
Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this O-Ring meets the exact dimensional tolerances required to maintain a proper oil-tight seal at the oil plate, preventing leaks that can lead to oil loss and engine damage.
- Direct-Fit Replacement — engineered to drop into place without modification, restoring the original sealing function of the oil plate assembly on compatible Honda engines and equipment.
- Broad Compatibility — fits GXV610, GXV620, and GXV670 vertical shaft engines, HA4118 and HA4120 lawn tractors, and HRC7018 and HRC7020 commercial mowers, including a range of serial number spans within each model.
- Verify Your Serial Number — Honda updates parts at production serial breaks, so cross-check your machine's serial number against the fitment table to confirm this is the correct O-Ring for your unit.
An oil plate O-Ring forms the static seal between the oil plate and the engine crankcase, keeping engine oil contained within the lubrication circuit. When this O-Ring degrades, shrinks, or takes a compression set over time, oil can seep past the mating surfaces, resulting in external leaks and a gradual drop in oil level. Replacing a worn O-Ring promptly protects the engine's internal components from the damage that follows oil starvation.
