The Honda 31110-Z4M-881 Flywheel (TEC) is a genuine OEM component designed for GX160 horizontal shaft engines. As a direct Honda replacement, this flywheel is manufactured to the same specifications as the original, ensuring correct magnetic pole geometry and rotational balance for the GX160. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes flywheel part numbers at specific serial breaks within the GX160 range.
Key Features
- Genuine OEM Magneto Integrity — manufactured by Honda to preserve the correct magnetic field strength and pole spacing critical to consistent spark timing on the GX160
- Exact Rotational Balance — matched to the GX160's crankshaft and ignition coil air gap specifications, so the charging and ignition systems perform as Honda engineered them
- Serial Number Matters — Honda issues this flywheel to specific production ranges of the GX160; check your engine serial number against the compatibility table to confirm this is the correct variant for your unit
- Fits GX160 Horizontal Shaft Engines — this is a model-specific part; confirm your GX160 serial range before ordering
The flywheel is a heavy rotating disc mounted directly to the crankshaft. On Honda GX160 engines it serves two purposes: its mass smooths out the power pulses of the combustion cycle to keep the engine running steadily, and the permanent magnets embedded in its rim pass by the ignition coil to generate the electrical charge that fires the spark plug. A flywheel that is cracked, has damaged magnets, or has a worn taper bore will cause hard starting, misfiring, or a complete loss of spark, and can also introduce harmful vibration throughout the engine.
