The Honda Q14-0000-020C Gear is a genuine OEM component designed for WDP20 and WDP30 diaphragm water pumps. Sourced directly from Honda, this gear matches the original specification for these pumps, ensuring proper mesh and drive engagement within the pump mechanism. Confirm your pump's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks.
Key Features
- Genuine OEM Fit — manufactured by Honda to the same specification as the original gear, ensuring correct tooth profile and dimensional accuracy for the WDP20 and WDP30 drive assembly.
- Diaphragm Pump Application — engineered specifically for Honda's WDP-series diaphragm water pumps; verify part number Q14-0000-020C against your pump's parts diagram to confirm this is the correct gear for your unit.
- Drive Integrity — a worn or damaged gear disrupts the crank-driven reciprocating action that moves the diaphragm, leading to reduced flow output or complete pump failure; replacing it restores consistent pumping performance.
- Serial Number Verification Recommended — Honda updates component specifications at serial number breaks, so cross-check your pump's serial number with the compatibility table to confirm applicability.
In Honda WDP20 and WDP30 diaphragm water pumps, a gear transmits rotational power from the engine through the pump's internal drive train, converting it into the reciprocating motion that actuates the diaphragm. When the gear wears or fails, drive motion cannot be transferred correctly, and the diaphragm stops cycling, bringing pumping output to a halt.
