The Honda 13310-Z0T-870 Crankshaft is a genuine OEM crankshaft designed for GX160 horizontal shaft engines, WB20 water pumps, and WB30 water pumps. As a direct Honda OEM component, this crankshaft is manufactured to the same specification as the original, ensuring correct stroke geometry, journal dimensions, and bearing fit right out of the box. Honda supersedes crankshaft part numbers at serial breaks, so verify your engine or pump serial number against the fitment table before ordering to confirm this is the correct part for your unit.
Key Features
- Genuine Honda OEM Component — sourced directly from Honda, this crankshaft matches the original in stroke length, journal diameter, and counterweight geometry — the dimensions that determine whether an engine runs smoothly or vibrates excessively
- Correct Bearing and Journal Fit — OEM crankshafts carry the exact bearing surface finish that Honda's connecting rod and main bearing tolerances are designed around, preventing premature wear at the rod and main journals
- Broad Fitment — designed for GX160 horizontal shaft engines as well as WB20 and WB30 water pumps; confirm your model and serial number against the fitment table before ordering
- Serial Number Verification Recommended — Honda updates crankshaft part numbers at specific serial breaks; always cross-reference your unit's serial number to ensure this is the correct supersession for your application
The crankshaft is the central rotating component of a four-stroke engine. It converts the linear up-and-down motion of the piston into rotational power that drives the output shaft — and, in the case of the WB20 and WB30 water pumps, ultimately spins the impeller that moves water. The crankshaft runs on precision main bearings and must maintain exact dimensional tolerances to keep the connecting rod, piston, and valvetrain in proper time with one another. A crankshaft that is worn, bent, or damaged at the journals causes excessive vibration, rapid bearing failure, and loss of compression, and in severe cases will prevent the engine from running at all.
