The Honda 78107-YE9-506 Volute Case is a genuine OEM replacement built for the WX10 water pump. As a direct Honda OEM component, this part is manufactured to the same specifications as the original, ensuring a correct fit in the pump housing. This Volute Case is designed specifically for the WX10, so buyers should confirm their unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM Construction — manufactured by Honda to match the original Volute Case exactly, preserving the pump's designed flow path and efficiency
- Direct OEM Replacement — replaces the original housing with no rework to surrounding pump components, restoring the impeller-to-volute relationship the WX10 depends on
- WX10 Water Pump Fitment — engineered specifically for the WX10 lightweight water pump; verify your unit's serial number against the compatibility table to confirm this is the correct case for your machine
- Restored Pump Output — a cracked or worn volute case disrupts internal pressure and reduces flow rate; replacing it with part number 78107-YE9-506 brings discharge performance back to spec
The volute case is the snail-shaped outer housing that surrounds the impeller inside a centrifugal water pump. As the impeller spins, the volute's gradually expanding chamber converts the rotating water's velocity into pressure, directing flow efficiently toward the discharge port. When the volute case cracks, warps, or wears, that conversion breaks down — the pump loses prime more easily, discharge pressure drops, and flow rate falls noticeably. Replacing a damaged case restores the tight clearances and smooth internal geometry the WX10 needs to move water reliably.
