The Honda 78107-YH4-610 Volute Case is a genuine OEM component designed for the WX10 water pump. Sourced directly from Honda, this replacement matches the original in every dimension, ensuring the pump's hydraulic passages are restored exactly as built. If your pump is losing prime, showing cracks in the housing, or delivering reduced flow, this part addresses the problem at its source.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specifications for the WX10, so the internal volute geometry matches the impeller clearances the pump was designed around.
- Restores Full Flow Performance — a cracked or damaged volute case breaks the sealed water passage, causing pressure loss and reduced output; replacing it with this part brings the pump back to its rated capacity.
- Direct WX10 Fitment — built specifically for the WX10 lightweight water pump; verify your unit's serial number against the fitment table to confirm this is the correct case for your production range.
The volute case is the primary pump housing that surrounds the impeller and converts the high-velocity water it spins into usable pressure and flow. Its spiral-shaped internal channel is engineered to a precise profile — any crack, fracture, or wear in this housing disrupts that channel, robbing the pump of prime and output. Replacing a compromised volute case is one of the most direct ways to return a centrifugal pump to its original pumping performance.
