The Honda Q14-026L Gear Box Gasket is a genuine OEM replacement designed for WDP20 and WDP30 diaphragm water pumps. Sourced directly from Honda, this gasket matches the original specification exactly, ensuring a proper seal without modification. If your diaphragm pump is showing signs of gear box leakage or you are performing a scheduled rebuild, this is the correct replacement part — confirm your serial number against the fitment table to make sure part number Q14-026L matches your production range.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's original specification, delivering the correct material grade and clamping retention needed to maintain a leak-free gear box joint in demanding pump operation
- Direct OEM Replacement — engineered as a drop-in fit for WDP20 and WDP30 diaphragm water pumps, matching original dimensions so no trimming or adjustment is needed at installation
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so check your pump's serial number against the fitment table to confirm this gasket applies to your unit
- Leak Prevention — a deteriorated or damaged gear box gasket allows fluid and lubricant to escape the gear box cavity, accelerating internal wear and reducing pump output; replacing this gasket restores the sealed boundary the drive assembly depends on
The gear box gasket forms the sealing interface between the gear box housing and its mating surface on Honda WDP-series diaphragm water pumps. When this gasket wears, cracks, or is disturbed during service, oil or grease can escape and external contaminants can enter, leading to accelerated wear of the internal drive components and eventual pump failure.
