The Honda 12361-891-000 Tappet Room Cover is a genuine OEM replacement designed for the GV400 vertical shaft engine. As a direct Honda OEM component, this cover is produced to the same specifications as the original part installed at the factory. This part fits the GV400 vertical shaft engine — verify your engine's serial number against the fitment table to confirm this is the correct cover for your unit, as Honda supersedes parts at serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring an exact match to the original tappet room cover in material, form, and fit for the GV400 engine.
- Proper Valve Train Enclosure — this cover seals the tappet room, keeping the valve train protected from contamination and retaining oil where it belongs, which is critical for correct engine operation.
- Serial Number Verification Recommended — Honda updates part supersessions at specific serial breaks, so confirm your GV400 serial number against the fitment table before ordering to ensure you receive the right part for your engine.
The tappet room cover encloses the valve train cavity on the GV400 vertical shaft engine, sealing in the oil that lubricates the tappets, pushrods, and rocker arms while keeping dirt and debris out. A damaged, cracked, or improperly seated cover will allow oil to leak and expose the valve train to contamination, leading to accelerated wear and potential engine damage. Replacing a faulty cover promptly keeps the valve train running clean and properly lubricated.
