GYMMEDS 30-Series Torque Converter Driver Pulley 3/4" Bore for Comet TAV2 — 6" OD, 3/16" Keyway, Iron-Aluminum

GYMMEDS 30 Series Torque Converter Driver Pulley is a direct-fit 3/4" bore replacement for 30-series Comet TAV2 CVT clutches, built to restore power transfer for 6.5HP (212cc) and similar small engines.

If your go-kart, mini bike, or small utility machine is using a Comet-style 30-series torque converter and the driver pulley is worn, this GYMMEDS replacement is engineered to match OEM dimensions while offering durable iron and aluminum construction. It’s intended for straight crankshafts with a 3/4" diameter and works across many 2HP–8HP engines, making it a practical service part when restoring CVT performance or swapping damaged pulleys.

Will this pulley fit my engine and clutch?

Yes—this pulley is built to the 30-series Comet TAV2 standard with a 3/4" bore and 3/16" keyway, so it fits engines that have a straight 3/4" crankshaft and torque converters that accept 30-series driver pulleys.

• 3/4" internal bore for straight crankshafts
• 3/16" keyway for secure shaft engagement
• 6" outer diameter matching 30-series specifications
• Compatible with many Comet TAV2-style housings

How durable and precise is the GYMMEDS replacement pulley?

This pulley combines iron and aluminum components to balance light weight with structural strength, aiming to reduce wear while keeping rotating mass reasonable for CVT responsiveness.

• Iron sections for long-term wear resistance
• Aluminum elements to lower overall weight
• Machined bore and keyway for accurate shaft fit
• Surface finish that resists premature belt slippage

What vehicles and applications can use this pulley?

Designed with broad compatibility, the 30 Series pulley suits small off-road vehicles and utility equipment that utilize 30-series torque converters; it’s a common choice for hobby and light-duty commercial machines.

• Go-karts, fun karts, and mini choppers
• Mini bikes and small ATVs
• Lawn mowers, small tractors, and utility carts
• Winches, water-ski winches, and other belt-driven accessories

How do I install and maintain this pulley for best results?

Installation generally requires removing the existing driver pulley, aligning the keyway, and tightening to OEM torque specifications; regular inspection of belt alignment and bearings will prolong service life.

• Ensure crankshaft diameter is 3/4" and key matches 3/16" slot
• Clean shaft and key before sliding pulley into place
• Torque to manufacturer specs and check belt tension
• Inspect periodically for wear, scoring, or imbalance
