The Honda 15631-ZM0-000 Oil Filler Extension is a genuine OEM component designed for GCV135, GCV160, GCV190, and GSV190 vertical shaft engines, as well as HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a proper fit within the oil fill system. Confirm your engine serial number against the fitment table before ordering, as Honda periodically updates components at serial number breaks.
Key Features
- Genuine Honda OEM Quality — sourced directly from Honda, this Oil Filler Extension meets the dimensional and material requirements Honda set for the original part, ensuring correct sealing and thread engagement at the fill point.
- Direct-Fit Replacement — engineered to install in place of the original without modification, restoring the oil fill port to its correct reach and orientation for clean, spill-free servicing.
- Broad Fitment Across GCV and GSV Engines — compatible with GCV135, GCV160, GCV190, and GSV190 vertical shaft engines, including a wide range of Honda walk-behind lawn mowers. Verify your serial number against the fitment table to confirm the correct variant for your unit.
- Proper Oil Servicing Made Simple — a correctly fitted extension keeps the fill tube accessible and properly positioned, so routine oil changes are clean and straightforward. A damaged or missing extension makes accurate fill-level servicing difficult and increases the risk of overfilling or spillage.
The Oil Filler Extension is a tube or neck fitted to the engine's oil fill port that lengthens and positions the opening for easier access during routine oil changes. On vertical shaft engines installed in walk-behind lawn mowers, the engine deck and housing can make the fill port difficult to reach directly, so the extension brings the opening to a more accessible point. When this component cracks, strips, or goes missing, adding oil cleanly becomes awkward and the risk of contaminating the engine bay with spilled oil increases — making prompt replacement straightforward preventive maintenance.
