The Honda 12311-ZG9-800 Head Cover is a genuine OEM replacement designed for GXV140 and GXV160 vertical shaft engines, including those powering HR215, HRA215, HRB215, HRC215, HRC216, HRM195, HR195, and HRM215 lawn mowers. As a factory-original component, this Head Cover meets Honda's exact specifications for fit and function, with no guesswork required on dimensions or mounting. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this cover must correspond to your specific unit.
Key Features
- Genuine OEM Sourcing — manufactured to Honda's exact specifications, ensuring proper sealing at the top of the engine and correct alignment with gasket surfaces
- Broad Vertical Engine Fitment — designed for GXV140 and GXV160 vertical shaft engines found across Honda's HR and HRM walk-behind lawn mower lines, including the HR195, HR215, HRA215, HRB215, HRC215, HRC216, HRM195, and HRM215
- Serial Number Verification Recommended — Honda updates part numbers at production breaks, so cross-reference your machine's serial number with the fitment table to confirm part number 12311-ZG9-800 is the correct cover for your unit
- Leak Prevention — a properly seated Head Cover keeps oil vapors contained and protects the valvetrain from contamination; a cracked or warped cover leads to oil seepage and potential engine damage over time
The Head Cover seals the top of the engine's cylinder head, enclosing the valvetrain components — including the rocker arms and valve stems — on Honda's GXV-series vertical shaft engines. It works in conjunction with a head cover gasket to prevent oil from escaping and to keep dirt and debris away from the internal valve gear. When the cover is cracked, warped, or its sealing surface is compromised, oil leaks onto the engine exterior and the valvetrain becomes vulnerable to contamination, which can accelerate wear and affect engine performance over time.
