The Honda Q14-0000-027 Washer is a genuine OEM replacement designed for the WDP20 and WDP30 diaphragm water pumps. Sourced directly from Honda, this washer is manufactured to the same standards as the original component installed at the factory. Honda supersedes parts at serial breaks, so confirm your pump's serial number against the fitment table before ordering to ensure part number Q14-0000-027 is the correct washer for your unit.
Key Features
- Genuine OEM Construction — a direct Honda-sourced washer, matching the original part in form and function for the WDP20 and WDP30 diaphragm water pumps
- Exact OEM Replacement — designed to drop in as a direct replacement without rework, maintaining the clamping and load-distribution characteristics of the original
- Serial Number Verification Recommended — Honda updates parts at production breakpoints, so cross-check your pump's serial number against the fitment table to confirm this is the right washer for your machine
A washer distributes the clamping load of a fastener across a broader surface area, protecting the mating components and maintaining consistent holding force under the vibration and operating stresses a diaphragm water pump produces. In a reciprocating diaphragm pump like the WDP20 and WDP30, consistent fastener load is especially important because the pumping action generates repeated mechanical pulses throughout the assembly. A worn, deformed, or missing washer can allow fastener tension to drop over time, leading to loosening and potential leaks or misalignment of the components it secures.
