The Honda 15631-Z0A-000 Oil Filler Extension is a genuine OEM component designed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines. As a direct OEM replacement, this part is manufactured to the same specification as the original, ensuring it seats and seals correctly in the engine it was built for. Verify your engine model and serial number against the fitment table before ordering, as Honda supersedes and revises parts at specific serial breaks across these engine families.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this extension matches the original in form and function, eliminating fitment guesswork on covered engine families.
- Correct Sealing Geometry — the extension is dimensioned to mate precisely with the oil filler opening on these vertical shaft engines, maintaining a proper seal against oil leaks during operation.
- Broad Vertical-Engine Coverage — fits GCV520, GCV530, GXV520, and GXV530 vertical shaft engines; check your serial number against the compatibility table to confirm the correct application.
- Accessible Oil Service — a functioning oil filler extension positions the fill point for easy access, supporting clean, mess-free oil changes and consistent engine maintenance intervals.
The oil filler extension is the tube or neck that connects the engine's oil filler opening to an accessible point on the engine housing, allowing oil to be added cleanly and without obstruction. On vertical shaft engines like the GCV520, GCV530, GXV520, and GXV530, this component directs oil into the crankcase and, along with its cap and seal, keeps the oil system closed during operation. A cracked, broken, or missing extension can allow oil to escape or contaminants to enter the crankcase, leading to accelerated wear and potential engine damage.
