The Honda 15631-Z9L-000 is a genuine OEM Oil Filler Extension designed for GCV170 and GCV200 vertical shaft engines, as well as HRN216 and HRX217 lawn mowers. As a direct Honda OEM component, this part is manufactured to the exact specifications of the original, ensuring a proper fit with no guesswork. If your current oil filler extension is cracked, damaged, or missing, this replacement restores clean, convenient access to the oil fill point. Confirm your machine's serial number against the fitment table before ordering to make sure part number 15631-Z9L-000 is the correct application for your unit.
Key Features
- Genuine Honda OEM Construction — manufactured to Honda's original specification, so the extension seats and seals exactly as the factory-installed part did
- Correct Oil Fill Access — restores the properly positioned fill point on GCV170 and GCV200 vertical shaft engines, making routine oil checks and changes straightforward
- Broad Fitment — covers GCV170 and GCV200 engines as well as HRN216 and HRX217 lawn mowers; verify your serial number against the fitment table to confirm the right application
- Prevents Contamination Risk — a damaged or absent oil filler extension exposes the fill opening, allowing debris into the crankcase and leading to accelerated wear
The Oil Filler Extension is a short tube or neck that connects to the engine's crankcase and provides an accessible, correctly positioned opening for adding and checking engine oil. On vertical shaft engines like the GCV170 and GCV200 — where the crankshaft exits downward to drive the blade on mowers such as the HRN216 and HRX217 — the extension routes the fill point to a location that is easy to reach during routine maintenance. When the extension is cracked, broken, or missing entirely, oil can leak from the fill area and debris can enter the crankcase, both of which put the engine at risk of rapid internal wear.
