The Honda 13310-ZM5-040 Crankshaft is a genuine OEM component designed for GX22 and GX31 horizontal shaft engines, the FG100 tiller, HHE31 stick edger, HHT31 and UMK422 and UMK431 trimmers, and the WX10 water pump. As a direct OEM replacement sourced from Honda, this crankshaft delivers the exact geometry and tolerances Honda specifies for these compact powertrains. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks across this range.
Key Features
- Genuine Honda OEM Part — manufactured to Honda's own specifications, ensuring the correct stroke, journal dimensions, and taper geometry for these small-displacement engines and equipment
- Broad Equipment Compatibility — fits GX22 and GX31 horizontal shaft engines, the FG100 tiller, HHE31 stick edger, HHT31, UMK422 and UMK431 trimmers, and the WX10 water pump, including a wide range of serial configurations across these platforms
- Serial Number Verification Recommended — Honda updates crankshaft part numbers at production breaks; check your machine's serial number against the compatibility table to confirm this is the correct crankshaft for your unit
- Core Engine Component — a worn or damaged crankshaft causes vibration, power loss, and accelerated wear on connecting rod and main bearings; replacing it with the correct OEM part restores smooth, balanced operation
The crankshaft is the central rotating component of an engine, converting the up-and-down motion of the piston into the rotational output that drives the equipment — whether that is the cutting line of a trimmer, the tine assembly of the FG100 tiller, the blade of the HHE31 edger, or the impeller of the WX10 water pump. It must be precisely balanced and dimensionally exact to run smoothly at the high speeds these compact Honda powerplants operate at. When a crankshaft is worn, bent, or damaged, the result is noticeable vibration, uneven power delivery, and rapid deterioration of the surrounding bearings and seals — making timely replacement with a correct OEM part essential to restoring full performance.
