Key Features
- Genuine OEM Fit — sourced directly from Honda, this Upper Mounting Case matches the original part exactly, eliminating the guesswork of aftermarket alternatives for a critical structural component.
- Diaphragm Pump Specific — engineered specifically for WDP20 and WDP30 diaphragm water pumps, ensuring proper alignment and secure assembly of the pump's mounting structure.
- Serial Number Awareness — Honda updates parts at production breaks, so verify your pump's serial number against the compatibility table to confirm part number Q14-0000-050A is the right fit for your unit.
The upper mounting case is a structural housing component on the WDP20 and WDP30 diaphragm water pumps. It forms part of the mounting assembly that secures and aligns the internal working components of the pump, keeping the reciprocating mechanism properly positioned during operation. A cracked, broken, or degraded mounting case can compromise the pump's alignment and overall structural integrity, leading to leaks, vibration, or pump failure.
