The Honda 13310-ZF6-W42 Crankshaft is a genuine OEM component designed for GX340 and GX390 horizontal shaft engines. As a direct Honda OEM part, this crankshaft is held to the same standards as the original, ensuring it seats and dimensions correctly within the engine block without rework or adaptation. This crankshaft is confirmed for GX340 and GX390 horizontal shaft engines — verify your engine's serial number against the fitment table before ordering, as Honda introduces part supersessions at specific serial breaks.
Key Features
- Genuine OEM Precision — manufactured by Honda to the exact tolerances required for proper bearing clearance, journal geometry, and crank throw — the dimensions that determine how well an engine runs and how long it lasts.
- Direct OEM Replacement — engineered to drop into GX340 and GX390 horizontal shaft engines in place of the original, with correct journal diameters and keyway geometry for a clean installation.
- Serial Number Matters — Honda supersedes crankshaft part numbers at specific production serial breaks; always confirm your engine's serial number against the compatibility table to ensure this is the correct crankshaft for your unit.
- Core Engine Performance — a crankshaft in good condition converts piston energy into smooth rotational output; a worn or damaged crankshaft causes excessive vibration, bearing failure, and loss of power.
The crankshaft is the backbone of a reciprocating engine. It converts the up-and-down motion of the piston into the rotational force that drives whatever equipment the engine powers. In GX340 and GX390 horizontal shaft engines, the crankshaft runs on precision bearings and must maintain tight journal tolerances to support correct oil film pressure and smooth power delivery. When a crankshaft wears beyond tolerance — or sustains damage from a sudden impact load or lubrication failure — the result is excessive vibration, rapid bearing wear, and ultimately engine failure. Replacing it with a genuine Honda OEM crankshaft restores the original geometry the engine was built around.
