The Honda Q14-034L55 Oil Dipstick with Discharge Valve is a genuine OEM component designed for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM replacement, this part is produced to the exact specifications of the original, ensuring a proper fit in the crankcase of these pumps. Confirm your pump's serial number against the fitment table before ordering, as Honda supersedes parts at defined serial breaks. This dipstick with integrated discharge valve is the correct service part to restore proper oil monitoring and crankcase drainage to your diaphragm water pump.
Key Features
- Genuine OEM Oil Sealing Integrity — manufactured by Honda to maintain an accurate oil level reading and a proper crankcase seal, preventing over- or under-lubrication of the pump's reciprocating assembly.
- Integrated Discharge Valve — combines the oil level dipstick and a crankcase discharge valve in a single assembly, allowing oil to be drained or purged without a separate drain plug removal.
- Serial Number Matters — Honda issues part supersessions at specific production breaks, so always verify your pump's serial number against the fitment table to confirm this is the correct version for your unit.
The oil dipstick with discharge valve serves two functions in a WDP-series diaphragm water pump. The dipstick portion lets the operator check crankcase oil level quickly and accurately, which is essential for keeping the pump's crank and connecting rod assembly properly lubricated during operation. The integrated discharge valve allows crankcase oil to be released during servicing or winterization without the need for a separate drain point — a practical feature on pumps that may be stored or transported frequently. When this part is damaged, missing, or improperly seated, the operator loses the ability to verify oil level reliably, which can lead to accelerated internal wear in the pump's drive mechanism.
