The Honda 13310-ZH9-821 Crankshaft is a genuine OEM Crankshaft designed for GX240 and GX270 horizontal shaft engines. As a direct Honda OEM component, this crankshaft is manufactured to the same specification as the original, ensuring proper balance, bearing journal dimensions, and stroke geometry for these engines. Honda supersedes parts at serial number breaks, so confirm part number 13310-ZH9-821 against your engine's serial number in the fitment table before ordering. A correct crankshaft replacement brings an engine back to its original power output and smooth running characteristics.
Key Features
- Genuine Honda OEM Crankshaft — sourced directly from Honda, this crankshaft meets the original journal tolerances and balance specs these engines were built around, not approximations
- Direct Replacement for GX240 and GX270 Engines — engineered specifically for GX240 and GX270 horizontal shaft engines, dropping into place without modification
- Restores Engine Power and Smoothness — a worn or damaged crankshaft causes vibration, bearing wear, and power loss; replacing it with this OEM part brings the engine back to proper operating condition
- Verify Your Serial Number — Honda updates part supersessions at specific serial breaks, so cross-check your engine's serial number against the compatibility table to confirm this is the correct crankshaft for your unit
The crankshaft is the backbone of a four-stroke engine's power cycle. It converts the up-and-down motion of the piston into the rotational output that drives the equipment the engine powers. Precision-machined bearing journals keep the rotating assembly centered and smooth; if those journals wear or the shaft bends from an impact, the engine will vibrate excessively, bearings will deteriorate rapidly, and output power will drop. Replacing a failed crankshaft with a genuine OEM unit restores the correct stroke, balance, and bearing fit that the GX240 and GX270 engines depend on for consistent, long-term operation.
