The Honda Q14-0001-204 Gear Box Aluminum Case (2D/3D) is a genuine OEM replacement designed for the WDP30 diaphragm water pump. As a direct Honda OEM component, this case is manufactured to the exact specifications Honda requires for the WDP30's gear box assembly. Honda supersedes parts at serial breaks, so confirm your pump's serial number against the fitment table before ordering to ensure part number Q14-0001-204 is the correct variant for your unit. The (2D/3D) designation identifies the specific configuration this case serves — match it carefully to your existing assembly.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this case meets the dimensional and material requirements of the WDP30 gear box, ensuring the internal drive components are correctly housed and aligned
- Exact Configuration Match — the (2D/3D) variant designation is part of the assembly specification; verify this matches your existing gear box before installation
- Serial Number Matters — Honda issues part supersessions at production breaks, so cross-reference your WDP30 serial number with the fitment table to confirm this is the right case for your pump
- Restores Drive Integrity — a cracked or damaged gear box case allows lubricant loss and exposes the gear set, leading to accelerated wear and pump failure; replacing it with this genuine part returns the assembly to a sealed, serviceable condition
The gear box on the WDP30 diaphragm water pump transfers power from the engine to the reciprocating crank mechanism that drives the diaphragm. The case encloses and protects the gear set, retains the gear lubricant, and provides the structural housing that keeps the drive components in correct mesh and alignment. When the case is cracked, broken, or compromised, lubricant escapes, the gear set runs dry, and the pump loses the ability to move water reliably. Replacing this case with the genuine Honda Q14-0001-204 restores the sealed housing the gear box requires to operate correctly.
