The Honda M55-TAF283730 Crank Bearing is a genuine OEM component designed for WDP20 and WDP30 diaphragm water pumps. Sourced directly from Honda, this bearing meets the same specifications as the original part installed at the factory. Honda supersedes parts at serial breaks, so confirm your pump's serial number against the fitment table before ordering to ensure part number M55-TAF283730 is the correct bearing for your unit.
Key Features
- Genuine OEM Precision — correct internal geometry and load ratings for the diaphragm pump crankshaft, ensuring smooth rotation and long service life under continuous pumping cycles
- Direct Replacement — installs in place of the original bearing with no rework, keeping your WDP20 or WDP30 back in service quickly
- Serial Number Awareness — Honda updates part numbers at production serial breaks; always verify your pump's serial number against the compatibility table to confirm this is the right bearing for your machine
- Protects the Drive Assembly — a worn crank bearing introduces play into the crankshaft, leading to uneven diaphragm stroke, reduced flow output, and accelerated wear on surrounding components
The crank bearing in a diaphragm water pump supports the crankshaft as it converts rotational motion into the reciprocating stroke that drives the diaphragm back and forth. When this bearing wears or fails, the crankshaft develops play, the diaphragm stroke becomes erratic, pumping efficiency drops, and internal components begin to wear prematurely.
