QYMOTO KT196 Go-Kart Driver Pulley 3/4" Bore for 30-Series Torque Converter — Includes Spacer & Bolt

The QYMOTO KT196 3/4" driver pulley is a direct-replacement torque converter component engineered to fit 30-series go-kart clutches and engines with a 3/4" straight crankshaft.

This replacement driver pulley from QYMOTO is built for hobbyists and repair pros who need a reliable pulley that mates to 30-series centrifugal clutches and common 6.5hp (212cc) engines. It arrives as a simple kit (driver pulley, spacer washer, and mounting bolt) so you can get back on track quickly. The KT196 is compatible with a wide range of consumer go karts and mini-bikes but is not intended for certain 16mm crankshaft minibike engines.

Will this pulley fit my go-kart or mini-bike engine?

Check your crankshaft diameter first: the KT196 is made for a straight 3/4" (0.75") crankshaft only. It works with many 30-series clutches and typical 6.5hp/212cc engines used in recreational go-karts and mini-bikes.

• Fits engines with 3/4" straight crankshaft bore
• Compatible with 30-series torque converter clutches
• Commonly used with 6.5hp (212cc) engines
• Not compatible with 16mm crankshaft Hisun Colemans

How does installing this driver pulley affect performance?

The pulley is a structural replacement part—when installed correctly it restores the torque converter’s intended mechanical engagement and power transfer. You should notice consistent belt engagement and reliable RPM response, assuming the rest of the drive components are in good shape.

• Re-establishes correct pulley-to-clutch fit
• Promotes stable belt contact and reduced slippage
• Helps maintain predictable acceleration and load handling

What comes in the package and what tools are required?

The KT196 unit ships with the driver pulley, a metal spacer washer, and the mounting bolt—everything needed for a basic swap. Installation typically requires common hand tools and basic mechanical skills; a torque wrench and thread-locker are recommended for a secure mount.

• Included: driver pulley, mounting bolt, metal spacer washer
• Suggested tools: socket set, torque wrench, thread-locking compound
• Typical time: 20–45 minutes depending on access and experience

Are there any fitment exceptions or compatibility notes?

Yes. While the KT196 fits a broad set of 30-series clutch systems, it is not universal. Inspect your crankshaft dimension and clutch model before ordering to avoid returns or improper fit.

• Designed for 3/4" straight crankshafts only
• Works with Comet, Trail Master, Manco, BT200X, Baja M200 style applications
• Does not fit 16mm crankshaft Hisun Coleman minibikes
