The Honda Q14-0000-068A Lower Case is a genuine OEM replacement built for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM component, this lower case is produced to the same specifications as the original part it replaces, ensuring a proper fit within the pump's housing assembly. This part is confirmed for WDP20 and WDP30 models — always cross-reference your pump's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this lower case meets the same dimensional and structural requirements as the original, maintaining the tight tolerances that a diaphragm pump's reciprocating mechanism depends on
- Direct Replacement Fit — engineered to drop into WDP20 and WDP30 diaphragm water pumps without modification, restoring the pump housing to its correct assembled form
- Verify Your Serial Number — Honda updates part supersessions at specific production breaks, so confirm your pump's serial number against the compatibility table to ensure part number Q14-0000-068A is the correct lower case for your unit
- Structural Integrity Restored — a cracked, broken, or worn lower case can compromise the pump's ability to hold alignment and contain internal components; replacing it with this OEM part brings the housing back to operating condition
The lower case forms the bottom section of the diaphragm water pump's main housing, enclosing and supporting the internal drive components that actuate the diaphragm. In a diaphragm pump like the WDP20 and WDP30, a reciprocating diaphragm driven by a crank and connecting rod moves water through the pump — and the lower case is a structural part of the assembly that keeps those components correctly aligned and protected. If the lower case is cracked, damaged, or missing, the pump cannot maintain its internal geometry, leading to poor pumping performance or complete pump failure.
