The Honda 31110-Z4M-910 Flywheel (Lamp) is a genuine OEM component designed for GX160 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring correct fitment and function on the GX160 without adaptation. Honda supersedes flywheel part numbers at production serial breaks, so verify your engine's serial number against the fitment table before ordering to confirm this is the right variant for your unit.
Key Features
- Genuine OEM Charging Output — manufactured by Honda to deliver the correct charging output for the lighting circuit on GX160 engines; aftermarket substitutes can fall short of the output the system requires.
- Direct OEM Replacement — replaces the original flywheel on GX160 horizontal shaft engines using existing hardware and mounting points, so the swap stays straightforward.
- Serial Number Verification Recommended — Honda issues multiple flywheel variants across GX160 production runs; cross-check your engine serial number against the fitment table to confirm part number 31110-Z4M-910 is correct for your specific unit.
- Ignition and Charging Integrity — a worn or damaged flywheel degrades both spark timing and lamp circuit charging, leading to hard starts and unreliable lighting output; a sound flywheel keeps both systems performing as designed.
The flywheel is a heavy rotating disc bolted to the crankshaft. On the GX160, the Flywheel (Lamp) variant carries additional magnets that work with a charging coil to supply current to a lighting circuit — in addition to providing the rotating magnetic field that triggers the ignition coil for spark. The flywheel's mass also acts as a mechanical reservoir of rotational energy, smoothing out the power pulses of the single-cylinder engine. When a flywheel is cracked, has damaged fins, or loses magnetism, the results show up as weak or absent spark, poor charging output, and rough running.
