The Honda 78101-YH4-610 Casing is a genuine OEM replacement built for the WX10 water pump. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a direct fit without guesswork. Verify your pump's serial number against the fitment table to confirm this casing is correct for your unit before ordering.
Key Features
- Genuine OEM Construction — manufactured by Honda to match the original casing in form and function, eliminating the fitment uncertainty that can come with non-OEM alternatives
- Direct WX10 Fitment — designed specifically for the WX10 water pump, so installation drops straight in using existing hardware and mounting points
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your pump's serial number against the fitment table to confirm part number 78101-YH4-610 is the right casing for your specific unit
- Pump Integrity Restored — the casing houses the pump's internal components and defines the flow path; a cracked or damaged casing causes pressure loss and water leakage, so replacing it promptly restores the pump to full output
The casing is the outer body of the WX10 water pump, enclosing the impeller and forming the volute — the shaped chamber that converts the impeller's rotational energy into flow and pressure. It directs water from the inlet, around the impeller, and out through the discharge port. When the casing is cracked, worn, or damaged, the pump loses the ability to build and hold pressure, resulting in reduced flow, leakage, or complete pump failure. Replacing a damaged casing with a genuine Honda part restores the tight internal clearances the impeller needs to move water efficiently.
