KRGUOD 3/4" Bore Centrifugal Clutch 12-Tooth with #35 Chain — Fits Predator 212 & Honda GC/GX, Includes Hardware

KRGUOD's 3/4" bore, 12-tooth centrifugal clutch with a #35 chain converts small-engine power into smooth, reliable drive engagement for minibikes, go-karts, mowers and other 2–6.5 HP applications.

This compact centrifugal clutch is designed to bolt directly to common small-engine crankshafts and deliver automatic engagement as RPM rises. Built for compatibility with Predator 212 and many Honda GC/GX, Briggs, Tecumseh and clone engines, the assembly includes a pre-measured #35 chain and the hardware needed for a straightforward swap or upgrade. The clutch is intended for riders and DIY mechanics who want a durable, easy-to-install drivetrain part that reduces manual shifting and improves power transfer for light vehicles and utility equipment.

Will this clutch fit my engine?

The clutch fits engines with a 3/4" (0.750") crankshaft diameter and a 3/16" keyway, making it compatible with Predator 212 and many Honda GC/GX models as well as numerous clone and OEM engines. Verify your crankshaft diameter and keyway before ordering to ensure proper fit.

• Designed for 3/4" crankshafts with 3/16" keyway
• Compatible with Predator 212, Honda GC/GX series, many Briggs/Tecumseh engines
• Works with most 4–7 HP and several 5.5–6.5 HP clone motors

• Chain length adjustable with supplied connecting link
• Mounts on crankshaft using bolt and washer; screws provide secondary security
• Typical install requires basic hand tools and a torque wrench for final tightening

What performance and durability features should I expect?

The clutch is engineered for repeated engagement cycles and steady power transfer at the rpm where centrifugal shoes expand. Materials and tooth profile are chosen to resist wear under normal recreational and light commercial use, while the #35 chain offers a compact, strong connection to your driven sprocket.

• 12-tooth profile balances torque delivery and chain life
• #35 chain with 130 links provides compact, robust drivetrain connection
• Hardware secures clutch against axial movement and slippage
• Suitable for minibikes, go-karts, mini choppers, lawn equipment and generators

How do I maintain the clutch for long life?

Routine inspection and basic maintenance will extend service life: keep the chain properly tensioned and lubricated, and periodically check mounting fasteners for tightness. Replace the chain or shoes if you notice excessive wear, slippage, or abnormal noises.

• Inspect chain tension and lubricate with light chain oil regularly
• Check mounting bolt and screws after initial run-in and at service intervals
• Replace worn shoes or chain links to prevent damage to sprockets
• Clean debris around clutch area to prevent overheating or binding

Who this is for: This KRGUOD centrifugal clutch is aimed at DIY mechanics, weekend builders and maintenance pros who need a dependable, compatible clutch for small engines—especially users of Predator 212 and Honda GC/GX engines—seeking easier drive engagement and a compact chain-drive solution for minibikes, go-karts, lawn equipment and light utility machines.
