GYMMEDS Torque Converter CVT Clutch for 3/4" Bore Engines – 30-Series Kit with Belt, 10T & 12T Sprockets (Fits Predator 212cc)

This complete drive kit replaces worn Comet/TAV2 30-series torque converters and is built for 3/4" straight crankshafts commonly found on Predator 212cc (6.5 hp) and other 2–7 HP engines. The kit combines durable iron and aluminum components with two sprocket options and a drive belt so you can swap between #35 and #40/41/420 chain drives. Designed for hobbyists and small-vehicle mechanics, it’s intended to restore performance, reduce engine load, and let you fine-tune engagement range with spring and setup changes.

Will this torque converter fit my engine and vehicle?

It fits engines with a 3/4" straight crankshaft and flat key, including many Predator 212cc and similar 2–7 HP motors. The kit replaces common Comet TAV2 30-series units and suits go-karts, mini bikes, ATVs, and other light equipment.

• Compatible with 3/4" straight-shaft engines with a flat key
• Recommended for Predator 212cc (6.5 hp) and similar engines
• Replaces Comet TAV2 30-series torque converters
• Works on go-karts, mini bikes, small tractors, and utility machines

What’s included and how difficult is installation?

The kit ships with driver pulleys, mounting plate, belt, two sprockets, a plastic cover, and full mounting hardware so you can complete a swap without hunting parts. Basic mechanical skills and common hand tools are all that’s required for most installs; follow engine-specific torque specs and alignment checks.

• 1 × 3/4" driver pulley and 1 × 5/8" driver pulley for flexibility
• 1 × 10T sprocket (#40/41/420 chain) and 1 × 12T sprocket (#35 chain)
• Aluminum mounting plate, plastic cover, belt, and full hardware kit
• Two screw kits: UNF and metric options for different crank threads

How does it affect performance and engagement?

The torque converter helps the engine deliver power more smoothly to the driven wheels by adjusting effective gearing through centrifugal action. Engagement is factory-like around mid RPM and can be tuned by changing springs and adjustments (springs not included) to shift engagement points for your application.

• Standard engagement around 2350 RPM, adjustable roughly 1200–3100 RPM with setup changes
• Reduces engine loading during low-speed operation for easier starts
• Aluminum and iron construction balances strength and weight savings
• Two sprocket choices let you match final drive ratios to your vehicle

What maintenance or parts should I plan for?

Routine checks include belt tension, visible wear on the pulley faces, sprocket condition, and secure fasteners. Replace springs or the belt if you notice slipping, inconsistent engagement, or unusual noises; chains and sprockets wear together and should be inspected regularly.

• Inspect belt and pulley faces after first few hours, then periodically
• Check sprocket teeth for wear and chain compatibility
• Keep mounting bolts torqued and keyed shaft properly aligned
• Swap springs to change engagement RPM as needed (not included)

Who is this for: This GYMMEDS 30 Series Torque Converter Kit is aimed at DIY mechanics, kart and mini-bike enthusiasts, small-farm equipment users, and anyone restoring or upgrading a Comet-style 30-series CVT on 3/4" straight-shaft engines. If you need a complete, ready-to-install replacement with sprocket options and both UNF and metric fasteners, this kit covers common fitments and offers the parts needed for a reliable drive rebuild.
