30 Series Torque Converter 3/4ft Bore for Predator 212cc - Direct Fit

Our review of the 30 Series Torque Converter 3/4' bore kit finds it best suited for hobbyists and small-vehicle owners who need a direct replacement for Comet TAV2 style units. This kit's single biggest selling point is its broad compatibility with 3/4' straight crankshafts, including Predator 212cc engines, making installation straightforward for repairs or upgrades. The reviewer noted the clear focus on fitment and a complete parts list in the kit, which simplifies swapping the clutch on go karts, mini bikes, and similar small engines.

Key Features

• Direct replacement: Fits Comet TAV2 30 series and other 3/4' straight crankshaft engines for an easy swap with existing setups.
• Wide engine fitment: Recommended for Predator 212cc 6.5 hp and most 2HP-7HP engines, so it works across many small vehicles and tools.
• Two sprockets included: Supplies a 12-tooth for #35 chain and a 10-tooth for #40/41/420 chain, letting users match common chain sizes without extra parts.
• Adjustable engagement range: Stock engagement is around 2350 RPM, and can be adjusted between 1200 and 3100 RPM by changing springs and settings.
• Complete hardware kit: Comes with driver pulleys, drive belt, plastic cover, aluminum mounting plate and full mounting hardware to reduce fitment guesswork.

Who It's For

This torque converter kit is intended for DIY mechanics, go-kart builders, and small-vehicle owners running engines with a 3/4' straight crankshaft who want a direct Comet-style replacement. The included parts and two sprockets make it practical for common repairs and rebuilds on mini bikes, go karts, ATVs and similar machines.

Those who should look elsewhere include users needing metric-precision performance tuning out of the box or buyers who want included spring sets for engagement tuning. If belt longevity and pulley grip under extreme loads are critical, consider sourcing higher-spec belts or aftermarket clutch components.

Pros & Cons

Pros

• Good overall build with iron and aluminum parts offering solid durability for routine use.
• Comprehensive kit contents make installation easier, including two driver pulleys and mounting hardware.
• Versatile fitment with two sprockets and compatibility across many 2HP-7HP engines.

Cons

• Belt durability has been reported as a concern by multiple users, so expect possible belt replacement sooner than ideal.
• Some users reported grip issues under extreme conditions, so high-stress applications may require additional upgrades.
