The Honda 13310-Z4H-730 Crankshaft is a genuine OEM component designed for GX120 horizontal shaft engines. As a direct Honda OEM part, this crankshaft is manufactured to the same specifications as the original, ensuring an exact fit with no guesswork at installation. This part is the correct replacement for GX120 engines requiring crankshaft service, and verifying your engine's serial number against the fitment table before ordering is always recommended, as Honda does supersede parts at serial number breaks.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this crankshaft meets the same dimensional and material standards as the original part it replaces, ensuring proper bearing journal dimensions and crank pin geometry for correct rod and bearing fit
- Direct OEM Replacement — engineered to drop into GX120 horizontal shaft engines using existing engine hardware, with no re-machining or adaptation needed
- Fits GX120 Horizontal Shaft Engines — purpose-built for the GX120 engine family; confirm your serial number against the fitment table to ensure this is the correct supersession for your unit
- Restores Full Power Stroke Integrity — a worn or damaged crankshaft causes vibration, bearing failure, and loss of power; replacing it with a genuine OEM crankshaft restores smooth, consistent power transfer from the piston to the output shaft
The crankshaft is the central rotating component of a four-stroke engine. It converts the up-and-down motion of the piston into the rotational force that drives the output shaft and, ultimately, the equipment the engine powers. The crankshaft runs in precision main bearings and must maintain exact journal dimensions to keep oil film pressure and bearing clearances within spec. When a crankshaft is worn, bent, or scored at the journals, the engine will produce excessive vibration, increased oil consumption, and eventually bearing seizure — making timely replacement critical to keeping a GX120 engine in service.
