The Honda 90751-YB9-003 Hinge Pin is a genuine OEM replacement designed for WT20, WT30, and WT40 water pumps. Sourced directly from Honda, this component matches the original specification for a direct, no-guesswork installation. As a genuine OEM part, it carries the same design and dimensional tolerances as the pin that left the factory, ensuring it seats correctly in the assembly. Always verify your pump's serial number against the fitment table to confirm this is the right pin for your unit.
Key Features
- Genuine OEM Construction — manufactured by Honda to the same specification as the original, ensuring correct fit and function in WT-series water pump applications
- Broad WT-Series Coverage — listed for the WT20, WT30, and WT40 water pumps, spanning Honda's core centrifugal pump lineup
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your pump's serial number against the fitment table before ordering
- Direct Replacement — replaces the worn or missing original pin without rework or modification to surrounding components
A hinge pin is a small but load-bearing fastener that joins two hinged components, allowing them to pivot while keeping them positively retained. On Honda WT-series water pumps, hinge pins are used in access panels, covers, and similar hinged assemblies to maintain alignment and keep those components secured during operation. A bent, corroded, or missing pin can prevent a cover from seating properly, leaving internal components exposed or causing vibration and noise during pump operation.
