The Honda Q14-0000-031 Washer is a genuine OEM replacement designed for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM component, it is manufactured to the same specifications as the original part that left the factory. This washer is listed for both the WDP20 and WDP30 — confirm the part number Q14-0000-031 against your pump's serial number and parts diagram before ordering to ensure you have the correct fitment for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original component in every dimension, ensuring proper seating and clamping when installed in your diaphragm water pump.
- Diaphragm Pump Fitment — listed for the Honda WDP20 and WDP30 diaphragm water pumps; verify part number Q14-0000-031 against your serial number and parts diagram before ordering.
- Correct Specification Matters — Honda supersedes hardware at serial breaks, so checking your pump's serial number against the fitment table is the best way to confirm this is the right washer for your machine.
A washer serves as a load-distributing fastener component, spreading clamping force evenly across the surface it bears against to protect mating parts and maintain a secure, stable assembly. In a diaphragm water pump such as the WDP20 and WDP30, where the reciprocating diaphragm and drivetrain components are subject to continuous mechanical stress, using the correct washer ensures that fasteners retain proper torque and mating surfaces are not damaged over time. A missing or incorrect washer can lead to fastener loosening, uneven clamping, or premature wear of the components it supports.
