caqeg 30-Series Torque Converter Kit for Go-Kart & Mini Bike — 3/4" Driver, 5/8" Driven 6" Pulley with 725 Belt

caqeg's 30 Series torque converter kit is a complete replacement clutch set for small-engine karts and mini machines, featuring a 3/4" driver clutch, 5/8" driven clutch, and a 725 drive belt.

Swap in this ready-to-install assembly when your go-kart, mini bike, or other light-duty equipment needs dependable power transfer. Designed to match common 30-series dimensions, the kit provides the main moving parts required for smooth CVT operation: a driver clutch with a 3/16" keyway and 3/4" bore, a 6" diameter driven pulley with a 5/8" bore, and a 725 V-belt sized to fit the package. All parts are new and intended to replace popular OEM items used on a variety of compact engines.

What parts are included and what do their sizes mean?

The kit contains a 3/4" bore driver clutch, a 5/8" bore driven clutch (6" diameter), and a 725-series V-belt. Bore measurements indicate the shaft diameter each clutch mounts to, while the driven pulley diameter affects belt wrap and final drive ratio.

• Driver clutch: 3/4" internal diameter, 3/16" keyway for secure shaft fit
• Driven pulley: 5/8" internal diameter, 6" outer diameter for standard 30-series fit
• Belt: 725 length, compatible with included clutch pair

How does this kit fit my go-kart or mini bike?

This assembly is made to match common 30-series dimensions used across many small recreational and utility machines. It replaces several widely used OEM part numbers, so it will fit machines that originally shipped with similar 30-series clutches and a 725 belt.

• Replaces common part numbers used on 30-series CVT setups
• Fits small engines typically up to roughly 7 HP when used as a direct swap
• Intended for go-karts, mini bikes, small ATVs, lawn equipment, and similar machines

What performance should I expect after installation?

Once properly installed and adjusted, the kit restores the expected automatic engagement and variable gearing behavior of a CVT system. You should see consistent belt engagement, predictable acceleration, and smooth idling under light loads when components are mounted correctly.

• Automatic engagement across RPM range for user-friendly operation
• Smoother acceleration compared with worn or mismatched clutches
• Durable construction for routine recreational and utility use

What do I need to install it and how do I maintain it?

Installation requires basic mechanical tools and a few minutes of setup if you are familiar with clutch swaps. Regular inspection and correct belt tension will keep the kit operating reliably; replace the belt if you notice cracking or glazing.

• Requires shaft key and correct torque on mounting hardware
• Check belt wear and adjust tension periodically
• Inspect clutch faces and springs for wear during routine maintenance

Who is this for: This caqeg 30 Series torque converter kit is aimed at hobbyists, DIY mechanics, and small-vehicle owners who need a direct replacement for worn or broken CVT components on go-karts, mini bikes, small ATVs, lawn machines, and portable equipment. If you need a straightforward replacement that matches common 30-series dimensions and keeps your small-engine machine running predictably, this kit gives the essential clutches and belt in one package.
