The Honda 31110-Z4M-871 Flywheel is a genuine OEM replacement built for GX160 horizontal shaft engines. Sourced directly from Honda, this flywheel is manufactured to the same specification as the original, ensuring correct mass, balance, and ignition trigger geometry for the GX160. Honda supersedes parts at serial number breaks, so confirm your engine's serial number against the fitment table before ordering to ensure this is the correct flywheel for your unit.
Key Features
- Genuine OEM Ignition Compatibility — carries the correct trigger magnet geometry to work with the GX160's ignition coil, ensuring accurate spark timing from the first start
- Balanced Rotating Mass — matched to the GX160's crankshaft to maintain smooth operation and reduce vibration at all running speeds
- Direct OEM Replacement — designed as a drop-in replacement for the original flywheel on GX160 horizontal shaft engines, with no modification needed to mounting hardware
- Serial Number Verification Advised — Honda updates part numbers across production runs; check your engine serial number against the compatibility table to confirm this flywheel applies to your GX160
The flywheel is a heavy rotating disc mounted to the crankshaft that serves two critical functions in the GX160 engine. First, its mass stores rotational energy between power strokes, keeping the crankshaft turning smoothly and preventing rough, uneven running. Second, it carries the permanent magnets that pass the ignition coil on every revolution, generating the electrical pulse that fires the spark plug. A cracked, damaged, or out-of-balance flywheel causes vibration, misfiring, or a complete no-start condition, making it one of the more consequential components in the engine's rotating assembly.
