The Honda 25611-733-000 Oil Cap is a genuine OEM replacement designed for F400, F401, F500, F501, FC600, FG400, and FG500 tillers, GX160 horizontal shaft engines, and the H3011 riding mower. As a direct OEM component, this oil cap is produced to Honda's original specifications, ensuring the correct fit and seal every time. Honda supersedes parts at serial number breaks, so verify your unit's serial number against the fitment table before ordering. This cap is the straightforward, by-the-book solution for restoring proper oil system closure on any of the covered models.
Key Features
- Genuine OEM Sealing — manufactured by Honda to the original specification, this oil cap delivers the correct thread engagement and seating seal to keep oil contained and contaminants out
- Broad Model Coverage — fits F400, F401, F500, F501, FC600, FG400, and FG500 tillers, GX160 horizontal shaft engines, and the H3011 riding mower, including models that share the same oil cap design across Honda's equipment lineup
- Check Your Serial Number — Honda updates part specifications at production breaks, so confirm your machine's serial number against the fitment table to ensure part number 25611-733-000 is correct for your unit
- Leak Prevention — a worn or damaged oil cap can allow oil to escape during operation or let dirt enter the crankcase; replacing it promptly protects the engine or drivetrain from contamination and oil loss
The oil cap seals the oil fill port on the engine or drivetrain crankcase, keeping the lubricating oil inside while blocking dirt, moisture, and debris from entering. A secure, properly seating cap is essential to maintaining correct oil level and preventing contamination that can accelerate internal wear. When an oil cap cracks, strips its threads, or loses its sealing ability, oil can leak out during operation and foreign matter can work its way in — both conditions that compromise lubrication and shorten the service life of the equipment.
