The Honda 13310-ZF6-W62 Crankshaft is a genuine OEM crankshaft designed for GX340 and GX390 horizontal shaft engines and the WT40 water pump. As a direct Honda OEM component, this crankshaft is manufactured to the same specifications as the original, ensuring a proper fit within the engine's rotating assembly. Honda supersedes parts across serial number ranges, so confirm your unit's serial number against the fitment table before ordering. This crankshaft is the correct choice when rebuilding or restoring an engine that has suffered crankshaft damage, excessive wear, or journal failure.
Key Features
- Genuine Honda OEM Component — sourced directly from Honda, this crankshaft matches the original in dimensional tolerances and journal geometry, which are critical to bearing clearance and engine balance
- Correct Rotating Assembly Fit — engineered to index precisely with Honda's connecting rod, main bearings, and timing components in GX340 and GX390 horizontal shaft engines and the WT40 water pump
- Serial Number Verification Recommended — Honda updates crankshaft part numbers at production serial breaks; cross-check your engine or pump serial number against the compatibility table to confirm this is the right part for your unit
- Restores Full Power Output — a worn or damaged crankshaft causes vibration, oil leaks at the main seals, and loss of compression transfer to the drivetrain; replacing it with this OEM part brings the engine back to proper operating condition
The crankshaft is the central rotating component of a four-stroke engine. On GX340 and GX390 horizontal shaft engines, and in the WT40 water pump's drive unit, the crankshaft also drives the camshaft through a gear set, timing the valve events to the piston position. When a crankshaft develops worn journals, a bent crank pin, or damaged keyways, the engine will vibrate excessively, lose power, or fail to run altogether — making crankshaft replacement one of the most significant but straightforward engine rebuild operations a technician will perform.
