The Honda 31110-Z5T-810 Flywheel (Lamp) is a genuine OEM component designed for GX340 and GX390 horizontal shaft engines, EG5000 and EG6500 generators, and HS928, HS1332, HSS928, and HSS1332 two-stage snow blowers. As a direct Honda OEM part, this flywheel is manufactured to the same specifications as the original, ensuring a correct fit and proper function right out of the box. Verify your unit's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks and more than one flywheel variant may be listed across this equipment range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this flywheel carries the correct lamp-type configuration, magnet placement, and dimensional tolerances required for accurate ignition timing and lighting coil output on compatible units.
- Broad Cross-Equipment Fitment — designed for use across GX340 and GX390 horizontal shaft engines, EG5000 and EG6500 generators, and HS928, HS1332, HSS928, and HSS1332 two-stage snow blowers, including models from multiple production series.
- Serial Number Verification Recommended — Honda supersedes flywheel part numbers at defined serial breaks; confirm your machine's serial number against the compatibility table to ensure this is the correct variant for your unit.
- Critical to Ignition and Charging — a cracked, damaged, or worn flywheel can cause misfires, rough running, or loss of lighting output; replacing it restores consistent spark timing and stable lamp circuit performance.
The flywheel is a heavy rotating disc bolted to the crankshaft that serves two roles in compatible Honda equipment. Its primary job is to store rotational energy and smooth out the pulses between power strokes, keeping the engine running evenly at all speeds. On lamp-type variants like this one, the flywheel also carries permanent magnets that pass a stator or lighting coil to generate the low-voltage AC current used to power work lights or charge a battery — a function critical on equipment such as generators and snow blowers where auxiliary lighting is part of the design. When a flywheel is cracked, out of balance, or has degraded magnets, the result can be hard starting, rough idle, erratic ignition timing, or loss of lighting output entirely.
