The Honda Q14-0000-043 Crank (3" Pump) is a genuine OEM replacement designed for the WDP30 diaphragm water pump. As a direct Honda OEM part, it is manufactured to the same specifications. This crank is listed for the WDP30, and the 3" qualifier identifies the variant — confirm this matches your unit before ordering. Always verify your pump's serial number against the fitment table to ensure you are selecting the correct part for your specific production run.
Key Features
- Genuine OEM Drivetrain Precision — sourced directly from Honda, this crank is built to the exact dimensional tolerances required to drive the diaphragm mechanism correctly in the WDP30 pump.
- Variant-Specific Fit — the 3" designation identifies this as the crank for the 3-inch pump configuration; confirm this matches your WDP30 before purchasing, as variant differences affect fitment.
- Serial Number Verification Recommended — Honda supersedes parts at serial number breaks, so cross-check your pump's serial number against the fitment table to confirm this is the right crank for your unit.
- Restored Pumping Action — a worn or damaged crank causes inconsistent diaphragm stroke, leading to reduced flow rate and output pressure; replacing it with this OEM part restores the pump's full displacement performance.
In a diaphragm water pump such as the WDP30, the crank converts the rotational output of the engine into the reciprocating motion that drives the diaphragm back and forth. When the crank wears or fails, the diaphragm stroke becomes erratic or stops entirely, and the pump loses the ability to move water reliably.
