SEHNSUCHT CVT Torque Converter Kit for 6.5HP Engines — 3/4" Bore, 3 Belts, Comet TAV2 Replacement

Built to fit common 6.5HP (212cc) horizontal-shaft engines, this complete drive kit includes a 3/4" bore driver clutch, a 6" driven pulley, three high-strength belts (plus two spares included within the three), and both 10-tooth and 12-tooth sprockets to match #40/#41/#420 and #35 chains. Constructed from iron and aluminum, the components are designed for robust torque transfer, heat dispersion, and long wear life while matching the footprint of Comet TAV2 Torq-A-Verter replacements.

How does this kit fit my engine and go kart setup?

The driver clutch accepts a 3/4" straight crankshaft with a flat key and is sized for popular 6.5HP horizontal engines. The assembled driven unit measures about 6" in overall diameter with a 5/8" driven pulley face to interface with the provided belts. A jackshaft with sprocket and full mounting hardware are included to simplify installation.

• Driver bore: 3/4" with flat key
• Driven diameter: 6" (5/8" driven pulley)
• Includes jackshaft, engine mount plate, and hardware
• Designed to match Comet TAV2 replacement dimensions

What belts and sprockets come with the package?

This kit ships with three reinforced belts sized for a center-to-center range of roughly 6-15/16" to 7" and an outside circumference near 27.76" (70.5 cm). You also get a 10-tooth sprocket that fits #40/#41/#420 chain standards and a 12-tooth sprocket for #35 chain installations, giving flexibility for different final-drive ratios.

• Belt length: 27.76" (70.5 cm); width: 3/4" (1.9 cm)
• Center-to-center pulley spacing recommended: 6-15/16" to 7"
• 10T sprocket for #40/#41/#420 chain, 12T sprocket for #35 chain
• Two extra belts provided as spares

How do I install and set belt orientation correctly?

When routing the belt, align the arrow marked on the belt so it faces downward toward the driven pulley as you install it. Most hardware arrives preassembled or partially assembled; follow the included mounting pattern, secure the engine mount plate, and confirm engagement range after installation. If needed, spring and engagement adjustments let you alter the engagement RPM band.

• Ensure belt arrow points down during installation
• Most components preassembled for faster setup
• Adjust springs (not included) to fine-tune engagement RPM
• Recheck chain alignment and torque after first run

What performance and durability can I expect?

Materials and construction are chosen for heavy-duty use: iron for strength where torque is highest and aluminum for lighter-weight sections that need heat dissipation. The kit is built to handle the loads typical of recreational mini bikes, go karts, and small utility vehicles without excessive slippage when installed correctly.

• Iron and aluminum construction for strength and cooling
• Engagement window roughly 2350 ± 200 RPM as shipped
• Rated for common 6.5HP (212cc) engine applications
• Suitable for repeated start/stop use in recreational vehicles

Who is this for: This SEHNSUCHT CVT torque converter kit is intended for DIY mechanics, kart builders, small-tractor and mini-bike owners, and repair shops replacing Comet TAV2-style units or retrofitting 3/4" shaft horizontal engines. It's best chosen by users who can confirm shaft and chain sizes, perform basic mechanical mounting, and who want a durable, ready-to-install replacement drive with extra belts and sprocket options included.
