The Honda 13310-Z6L-000 Crankshaft (L=138) is a genuine OEM crankshaft designed for GX630, GX660, and GX690 horizontal shaft engines. As a direct Honda OEM component, this crankshaft is manufactured to the same specification as the part it replaces, ensuring the correct stroke geometry and journal dimensions your engine depends on. This part fits GX630, GX660, and GX690 engines — confirm your engine's serial number against the fitment table before ordering, as Honda supersedes crankshaft part numbers at defined serial breaks.
Key Features
- Genuine OEM Crankshaft — sourced directly from Honda, this crankshaft delivers the exact stroke length, journal sizing, and dimensional tolerances the GX630, GX660, and GX690 engines were engineered around
- L=138 Variant — the L=138 designation identifies the specific stroke dimension of this crankshaft; match this to your engine's specification before ordering, as alternative stroke variants exist for this engine family
- Direct OEM Replacement — replaces the original crankshaft on covered GX630, GX660, and GX690 horizontal shaft engines with no adaptation required to fit Honda's existing engine architecture
- Serial Number Verification Recommended — Honda releases revised crankshaft part numbers at defined production breaks; cross-reference your engine's serial number with the compatibility table to confirm this is the correct part for your unit
- Restores Full Power Output — a worn, bent, or damaged crankshaft causes vibration, power loss, and premature bearing wear; replacing it with the correct OEM part returns the engine to its intended operating balance and output
The crankshaft is the central rotating component of a four-stroke engine, converting the up-and-down motion of the piston into the rotational force that drives whatever the engine powers. On large-displacement horizontal shaft engines like the GX630, GX660, and GX690, the crankshaft must maintain precise dimensional tolerances to keep bearing clearances correct, combustion timing accurate, and power delivery smooth. A crankshaft that is bent, worn at the journals, or otherwise damaged will produce noticeable vibration, accelerated bearing failure, and a significant drop in output — making timely replacement with the correct OEM part essential to restoring the engine to full service.
