The Honda 13310-Z4H-620 Crankshaft is a genuine OEM component designed for GX120 horizontal shaft engines. Sourced directly from Honda, this crankshaft is manufactured to the same specification as the original part it replaces, ensuring a correct fit without modification. If your GX120 engine is showing signs of crankshaft wear — such as excessive vibration, oil leakage at the main seals, or loss of power output — this is the direct OEM replacement to restore it to proper working condition. Always verify your engine's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- Genuine Honda OEM Part — manufactured to the same standards as the original crankshaft, ensuring correct journal dimensions, stroke geometry, and bearing surface finish for the GX120 engine
- Direct OEM Replacement — this crankshaft is designed to drop into the GX120 engine block as a direct replacement, with no secondary machining or adaptation needed
- GX120 Fitment — built specifically for GX120 horizontal shaft engines; confirm your serial number against the fitment table to ensure this is the correct crankshaft for your engine's production range
- Restores Engine Output — a worn or damaged crankshaft causes vibration, loss of compression, and accelerated wear on connecting rod bearings and main seals; replacing it with this OEM part brings the engine back to proper running condition
The crankshaft is the central rotating component of a four-stroke engine, converting the linear force of the piston and connecting rod into the rotational power that drives the equipment. On horizontal shaft engines like the GX120, the crankshaft also drives the camshaft through a gear set, timing the opening and closing of the engine's valves. When a crankshaft develops wear at the journal surfaces, bends from a sudden impact strike, or fails at the keyway, the engine will run rough, lose power, or fail to start — making timely replacement critical to restoring full operation.
