The Honda 78101-YH5-610 Casing is a genuine OEM component designed for the WX15 water pump. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a correct fit without guesswork or modification. If you are restoring a worn or damaged pump housing, this casing is the right replacement to bring your WX15 back to its original operating condition.
Key Features
- Genuine Honda OEM Construction — manufactured to Honda's original specifications for the WX15, so dimensions and porting match the pump's designed flow path exactly
- Direct Replacement — engineered to replace the original casing on the WX15 water pump with no rework needed; correct part number 78101-YH5-610 ensures the right component every time
- Fitment — confirmed for WX15 water pumps; verify your unit's serial number against the fitment table before ordering to account for any Honda mid-production part updates
- Restore Flow Performance — a cracked, worn, or damaged casing compromises the pump's ability to build and hold pressure; replacing it returns the WX15 to its full pumping capacity
The casing is the main outer housing of the WX15 water pump's hydraulic section. It forms the volute chamber that surrounds the impeller, directing water flow from the inlet port to the discharge outlet and converting the impeller's rotational energy into pressure and flow. When the casing is cracked, eroded, or damaged, the pump loses the ability to maintain suction and build discharge pressure, resulting in reduced flow rate or a complete loss of pumping ability. Replacing a failed casing restores the sealed hydraulic path the pump depends on to move water efficiently.
