The Honda 04101-ZM5-020 Crankshaft is a genuine OEM component designed for GX22 and GX31 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same tolerances as the original, ensuring correct fit within the engine assembly. This crankshaft is the right choice for technicians and equipment owners restoring a GX22 or GX31 engine to full working order. Always confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this crankshaft is manufactured to the same dimensional specifications as the part it replaces, ensuring correct bearing journal sizing and stroke geometry for GX22 and GX31 engines.
- Direct Engine Fit — engineered specifically for GX22 and GX31 horizontal shaft engines, this crankshaft installs without modification and aligns correctly with the connecting rod, main bearings, and PTO components.
- Serial Number Verification Recommended — Honda updates crankshaft part numbers at production serial breaks; check your engine's serial number against the compatibility table to confirm this is the correct crankshaft for your unit.
- Core to Engine Performance — a worn or damaged crankshaft causes vibration, bearing failure, and loss of power; replacing it with a genuine OEM part restores smooth power delivery and protects the surrounding drivetrain components.
The crankshaft is the central rotating component of a four-stroke engine. It converts the up-and-down motion of the piston into the rotary output that drives the equipment the engine powers. In Honda's compact GX22 and GX31 horizontal shaft engines, the crankshaft runs in precision main bearings and drives both the connecting rod above and the PTO shaft at the output end. When a crankshaft is worn, bent, or damaged — whether from a sudden impact, lubrication failure, or extended service — the engine will run rough, lose output, or refuse to start, and continued operation risks damage to bearings, the block, and connected components.
