The Honda 78130-YE9-505 Mechanical Seal Assembly is a genuine OEM component designed for the WX10 water pump. As a direct Honda OEM part, it is manufactured to the same specification as the original unit it replaces, ensuring a proper fit without guesswork. This assembly is the correct service replacement for WX10 pumps and carries part number 78130-YE9-505 for straightforward verification against your machine's parts diagram. Always confirm your pump's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks.
Key Features
- Genuine Honda OEM Seal — manufactured to Honda's original specification, ensuring the sealing surfaces and dimensional tolerances match the WX10 pump's design exactly
- Stops Shaft Leakage — a correctly functioning mechanical seal prevents water from escaping along the impeller shaft; a worn or degraded seal leads to visible leaking, pump inefficiency, and eventual bearing damage
- Direct WX10 Fitment — built specifically for the WX10 lightweight water pump; verify your serial number against the fitment table to confirm this is the right service assembly for your unit
- Assembly Convenience — supplied as a complete seal assembly rather than individual components, streamlining the repair and reducing the risk of mismatched parts during rebuild
A mechanical seal assembly controls leakage where the rotating impeller shaft passes through the pump housing. It consists of paired sealing faces — one stationary, one rotating — held in contact by spring pressure to form a fluid-tight barrier. When this seal wears or fails, water finds its way past the shaft, resulting in external leaking, loss of prime, and reduced output pressure. Replacing the Mechanical Seal Assembly with a genuine Honda part restores the WX10 to a leak-free, full-output condition and protects the shaft and surrounding components from water ingress damage.
