The Honda Q14-0000-187 Stud (12X1.75-70) is a genuine OEM stud designed for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM component, this stud matches the original specification exactly, ensuring correct thread engagement and proper clamping load when reassembling your pump. It is compatible with WDP20 and WDP30 diaphragm water pumps — always verify your unit's serial number against the fitment table to confirm this is the correct part for your production range.
Key Features
- Genuine OEM Thread Integrity — sourced directly from Honda, this stud carries the correct 12 x 1.75 mm thread specification, ensuring full thread engagement and consistent clamping force on reassembly.
- Direct OEM Replacement — engineered to Honda's original dimensions, this part installs without modification, restoring the pump to its original assembled configuration.
- WDP20 and WDP30 Fitment — designed specifically for Honda's diaphragm water pump line. Confirm your serial number against the fitment table before ordering, as Honda periodically supersedes hardware at production breaks.
A stud is a headless threaded fastener used to clamp major pump components together under repeatable, controlled load. On the WDP20 and WDP30 diaphragm water pumps, correctly torqued studs maintain the joint integrity that keeps the pump's reciprocating diaphragm mechanism sealed and operating as intended. A damaged, stretched, or incorrect stud can compromise clamping force, leading to leaks or joint failure during pump operation.
