The Honda 90751-YE0-003 Key is a genuine OEM replacement designed for the WMP20 water pump. Sourced directly from Honda, this part matches the original specification exactly, ensuring correct fitment without guesswork. If your existing key is worn, sheared, or lost, this is the correct replacement to restore proper drive engagement on your WMP20.
Key Features
- Genuine OEM Part — supplied directly by Honda, identical to the key installed at the factory on the WMP20 water pump
- Exact Dimensional Match — machined to the correct width and depth to seat properly in the shaft and hub keyways of the WMP20
- Serial Number Verification Recommended — Honda updates parts at production breaks, so confirm your unit's serial number against the fitment table before ordering
A key is a small, precisely sized component that locks a rotating shaft to a hub — in this case, securing the pump's drive components so torque transfers cleanly from the engine to the pump mechanism. When a key is sheared or worn, the shaft spins independently of the hub, causing the pump to lose drive and output water pressure to drop to zero. Replacing a damaged key with the correct OEM part restores the positive mechanical connection and returns the WMP20 to full pumping performance.
