The Honda 13310-Z0S-970 Crankshaft is a genuine OEM component built for GX120 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring the dimensional accuracy that proper engine assembly demands. This crankshaft is the correct replacement for GX120 engines — confirm your engine serial number against the fitment table before ordering, as Honda supersedes parts at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this crankshaft meets the original design specification for the GX120, covering journal dimensions, stroke, and bearing tolerances that aftermarket alternatives may not match.
- Exact Dimensional Fit — the crankshaft is machined to OEM tolerances, allowing correct alignment with the connecting rod, main bearings, and PTO end components without rework or shimming.
- Engine Performance Restored — a worn or damaged crankshaft causes vibration, oil leaks at the main seals, and loss of power; replacing it with this OEM unit brings the engine back to its designed output and smooth operation.
- Serial Number Verification Recommended — Honda updates crankshaft part numbers at specific serial breaks on the GX120; check your engine serial number against the compatibility table to confirm this is the correct part for your unit.
The crankshaft is the central rotating component of the engine. It converts the up-and-down motion of the piston into the rotational output that drives the equipment. On GX120 horizontal shaft engines, the crankshaft runs in precision main bearings at each end of the crankcase and connects to the piston via the connecting rod at the crankpin journal. When a crankshaft is worn, bent, or damaged at the journals, the engine will run roughly, consume excessive oil, and may ultimately seize — making timely replacement essential to keeping the engine serviceable.
