The Honda 78101-YE9-505 Casing is a genuine OEM replacement designed for the WX10 water pump. Sourced directly from Honda, this part is manufactured to the exact specifications of the original, ensuring a correct fit and consistent pump performance. If your existing casing is cracked, worn, or damaged, this component restores the structural integrity of the pump's water-handling assembly. Verify your pump's serial number against the fitment table before ordering to confirm this is the right part for your unit.
Key Features
- Genuine OEM Construction — manufactured by Honda to the same specification as the original, so the pump's flow path and sealing surfaces are maintained exactly as designed.
- Direct Replacement for the WX10 — built specifically for the WX10 water pump, this casing installs in place of the original without alteration.
- Restores Pump Integrity — a damaged or cracked casing causes pressure loss and leaks; replacing it with this genuine part brings the pump back to proper working condition.
- Check Your Serial Number — Honda updates parts at production breaks, so confirm your pump's serial number against the compatibility table to ensure part number 78101-YE9-505 is the correct casing for your machine.
The casing is the main housing that surrounds the impeller on a centrifugal water pump, forming the volute — the curved chamber that converts the impeller's rotational energy into water flow and pressure. It also provides the inlet and outlet ports through which water enters and exits the pump. When the casing is cracked or worn, the pump loses the ability to build pressure efficiently, resulting in reduced flow rate and potential leakage that can worsen quickly under load.
