The Honda Q14-0000-054 Roll Pin is a genuine OEM replacement built for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM component, this roll pin is manufactured to the same specifications as the original, ensuring a correct fit within the pump assembly. It is compatible with both the WDP20 and WDP30 diaphragm water pumps — confirm your pump's serial number against the fitment table before ordering to ensure this is the right part for your machine.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this roll pin matches the original component exactly, eliminating fitment guesswork on your WDP20 or WDP30.
- Diaphragm Pump Specific — designed for use in Honda's WDP-series diaphragm water pumps; verify your serial number against the fitment table to confirm the correct application.
- Precise Retention — a correctly fitted roll pin secures moving or assembled components in position; a worn, sheared, or missing pin can allow components to shift and disrupt pump operation.
A roll pin is a small but essential fastening and locating component used within mechanical assemblies. In Honda's WDP20 and WDP30 diaphragm water pumps, it holds a shaft, linkage, or assembled part in its correct position, preventing unwanted movement during the pump's reciprocating diaphragm action. When a roll pin shears or works loose, the components it locates can shift out of alignment, leading to reduced pump performance or mechanical failure.
