YOHIB 30 Series Torque Converter Clutch Driver Pulley Kit — 3/4" Bore, Direct-Fit 2–8 HP with Replacement Belt

YOHIB's 30 Series torque converter clutch driver pulley is a direct-fit replacement for Comet/Manco 30-series kits, built for 2–8 HP small engines with a 3/4" bore and compatible drive belt.

This complete clutch driver and belt set swaps into common go-kart and mini-bike torque converter installations to restore smooth, reliable power transfer. Designed to match the form and function of the Comet TAV2-style 30 series, the assembly works with 5–7 HP recreational karts and supports engines up to 8 HP. Included belt and pulley sizing make it a practical service or upgrade part for hobbyists and fleet operators alike.

How will this torque converter improve my go-kart or mini-bike performance?

Replacing a worn or mismatched clutch driver restores correct belt engagement and torque delivery, reducing slipping and improving acceleration under load. The 30 series profile is engineered to mimic the factory Comet/Manco geometry so pulley angles and belt seating behave the way manufacturers intended.

• Direct-fit 30 series driver profile for consistent belt tracking
• 3/4" bore to suit common small-engine shafts
• Compatible with engines from 2 HP up to 8 HP for wide application
• Includes a replacement drive belt sized for Manco 5959 / Comet 203589 swaps

Which engines and machines is this compatible with?

The kit is made for small gasoline engines typically found on go-karts, mini bikes, and similar recreational equipment. It suits most Comet TAV2-style bolt-on torque-a-verter setups and works with a broad range of brands that use 30 series hardware.

• Recommended engine range: 2 HP to 8 HP (commonly used with 5–7 HP karts)
• Fits go-karts, mini bikes, lawn equipment, fun karts, and mini choppers
• Works on many Manco, Comet, American Sportworks, and Ken-Bar applications
• Center-to-center driver/driven pulley spacing: 6 5/8" to 6 11/16"

Is this a true direct replacement for Comet and Manco parts?

Yes — the YOHIB 30 Series unit was produced to interchange with common Comet/Manco part numbers and mounting patterns. You’ll get a compatible bore, face width and belt profile so installation is straightforward for anyone familiar with torque converter servicing.

• Interchanges with Comet TAV2 30-series hardware
• Replaces Manco part 5959 and Comet part 203589 belt sizes
• 3/4" maximum bore matches standard small-engine shafts
• Supplied as a clutch and belt replacement kit for convenience

What should I check before buying and installing this kit?

Measure the existing shaft bore, confirm the required center-to-center distance between driver and driven pulleys, and match the engine horsepower range to ensure proper fit and longevity. Also inspect the driven pulley and mounting hardware for wear; replacing both pulleys at once prevents premature belt failure.

• Verify shaft diameter is 3/4" or compatible with supplied bore
• Confirm pulley spacing between 6 5/8" and 6 11/16"
• Match your engine horsepower to the recommended 2–8 HP range
• Consider replacing the driven pulley if heavily worn for best results
