Honda GX35 Air Filter

The Honda GX160 Flywheel GCBCH (OEM 31110-Z4M-950) is a replacement flywheel for Honda GX160 engines with the GCBCH serial number prefix. Mounted on the end of the crankshaft, the flywheel stores rotational energy to keep the engine running smoothly between power strokes. It also carries the magnets that work with the ignition coil to generate the spark.

This part number supersedes the earlier flywheel reference 31110-Z1T-931. It is suitable for the standard recoil-start version of the engine. Replacing a damaged or cracked flywheel, or one with weakened magnets, helps restore reliable starting, correct ignition and smooth engine running.

FUNCTION AND OPERATION

• Stores rotational energy to smooth out engine running between power strokes.
• Helps maintain consistent engine speed under load.
• Carries the magnets that trigger the ignition coil to produce the spark.
• Located on the crankshaft by the flywheel key and secured with the flywheel nut.
• Provides a replacement for a cracked, damaged or out-of-balance flywheel.
