The Honda 13310-Z6L-620 Crankshaft (L=158.5) 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 exact dimensional specifications required by these large-displacement GX-series engines. 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 part for your unit. A properly matched crankshaft is essential to keeping these high-output engines running smoothly and reliably.
Key Features
- Genuine OEM Dimensional Accuracy — sourced directly from Honda, this crankshaft carries the exact stroke length (L=158.5) required by the GX630, GX660, and GX690 — a specification that aftermarket alternatives may not match with the same precision.
- Direct OEM Replacement — engineered to drop into GX630, GX660, and GX690 horizontal shaft engines without alteration, maintaining correct bearing journal fit, rod throw alignment, and PTO-end geometry.
- GX-Series Fitment — covers Honda's GX630, GX660, and GX690 horizontal shaft engines; always verify your engine serial number against the compatibility table, as Honda issues part supersessions at specific serial breaks.
- Stroke-Variant Identification — the L=158.5 designation is a critical dimension; ordering the wrong-length crankshaft will result in a non-functional assembly, so match this value to your engine's specification before purchasing.
- Restores Full Power Output — a worn, cracked, or damaged crankshaft causes vibration, bearing failure, and loss of power; replacing it with the correct OEM part returns the engine to proper operating condition.
The crankshaft is the central rotating component of a reciprocating engine. It converts the up-and-down motion of the pistons into the rotational power that drives the equipment the engine is mounted to. On large-displacement engines like the GX630, GX660, and GX690, the crankshaft must withstand significant combustion forces and rotational loads cycle after cycle — making dimensional accuracy and material integrity critical. When a crankshaft develops wear at the rod or main journals, or sustains damage from a sudden mechanical event, the result is typically excessive vibration, knocking, rapid bearing wear, or a seized engine; replacement with a correctly specified OEM part is the only path to restoring full function.
