The Honda 31110-Z4M-810 Flywheel (Lamp) is a genuine OEM component designed for GX160 horizontal shaft engines. Sourced directly from Honda, this flywheel carries the same specifications as the part installed at the factory, ensuring it integrates correctly with the ignition and charging systems on your GX160. Verify your engine's serial number against the fitment table before ordering, as Honda updates part numbers at serial breaks and this flywheel is specific to the lamp-equipped variant of the GX160.
Key Features
- Genuine OEM Flywheel — manufactured by Honda to the exact specifications of the original, ensuring correct magnetic pole geometry for consistent spark timing and lamp charging output on GX160 engines.
- Lamp Variant — this is the lamp-equipped flywheel, which includes the charging magnets needed to power the lighting coil. Confirm your GX160 uses this configuration before ordering.
- Direct OEM Replacement — designed as a drop-in replacement for GX160 horizontal shaft engines using part number 31110-Z4M-810; no adaptation required.
- Serial Number Matters — Honda supersedes flywheel part numbers at specific serial breaks; check your engine's serial number against the compatibility table to confirm this is the correct unit for your machine.
The flywheel is a heavy rotating disc mounted on the crankshaft that serves two critical roles. First, its mass stores rotational energy and smooths out the power pulses of the combustion cycle, keeping the engine running steadily between firing strokes. Second, on lamp-equipped GX160 engines, permanent magnets embedded in the flywheel pass by a stator coil as the flywheel spins, generating the AC current that powers lighting circuits. A flywheel that is cracked, has damaged magnets, or is incorrectly keyed to the crankshaft will cause misfires, weak or no spark, or loss of lighting output — all symptoms that demand immediate replacement to restore proper engine function.
