The Honda 13310-Z4H-900 Crankshaft is a genuine OEM component designed for the GX120 horizontal shaft engine. As a direct Honda OEM part, it is manufactured to the exact tolerances required to maintain proper bearing clearances, journal geometry, and stroke precision in the GX120. Buyers should verify their engine's serial number against the fitment table to confirm part number 13310-Z4H-900 is the correct application for their unit.
Key Features
- Genuine Honda OEM Construction — manufactured to the exact dimensional tolerances Honda specifies for the GX120, ensuring correct bearing journal fit and stroke geometry rather than an approximated replacement dimension
- Restores Core Engine Function — a worn or damaged crankshaft causes vibration, loss of power, bearing failure, and ultimately engine seizure; this crankshaft returns the GX120 to full, smooth power delivery
- GX120 Fitment — engineered specifically for the GX120 horizontal shaft engine; verify your serial number against the fitment table before ordering, as Honda supersedes crankshaft part numbers at serial production breaks
The crankshaft is the central rotating component of the engine. It converts the linear motion of the piston into the rotational output that drives the equipment the engine powers. On the GX120, the crankshaft also drives the camshaft through the timing gear arrangement, synchronizing the valve train with each power stroke. When a crankshaft develops worn journals, a bent crank pin, or damaged keyways, the engine will run rough, lose output, or fail to start — making a correct OEM replacement critical to restoring service.
