The Honda 13310-ZH9-651 Crankshaft is a genuine OEM Crankshaft designed for GX240 and GX270 horizontal shaft engines. As a direct Honda OEM component, this crankshaft is manufactured to the same specification as the part originally installed at the factory. Honda supersedes crankshaft part numbers at serial breaks, so confirm your engine's serial number against the fitment table before ordering to ensure this is the correct crankshaft for your unit. This part is the right choice when a worn, damaged, or out-of-spec crankshaft needs a full, reliable replacement rather than a patch repair.
Key Features
- Genuine Honda OEM Construction — manufactured to Honda's original dimensional tolerances for correct journal geometry, rod throw dimensions, and bearing fit — the specs that directly govern how cleanly the engine runs
- Drop-In Replacement — engineered to the same interface dimensions as the original crankshaft, so it installs without machining or custom fitting
- GX240 and GX270 Fitment — sourced directly from Honda's parts catalogue for these two horizontal shaft engine families; use part number 13310-ZH9-651 to verify against your engine's parts diagram
- Serial Number Matters — Honda updates crankshaft part numbers mid-production run; cross-reference your engine's serial number with the fitment table to confirm this is the right supersession for your build
- Core Engine Component — a crankshaft that is bent, scored, or worn beyond spec causes vibration, bearing damage, and loss of power; replacing it with an OEM-specification part restores smooth, balanced engine operation
The crankshaft is the central rotating component of a four-stroke engine, converting the up-and-down motion of the piston into the rotational output that drives the equipment. It runs on precision main bearings inside the crankcase, and its rod journal drives the connecting rod that links it to the piston. When a crankshaft is bent from a sudden overload strike, or its journals are worn beyond the allowable clearance, the result is excessive vibration, rapid bearing wear, and ultimately engine failure — making a correct OEM-specification replacement the only sound repair path.
