The reviewer found the kit to be a direct-fit substitute for Comet TAV2 units that accept a 3\/4 in straight crankshaft, and highlighted the included dual sprockets and complete mounting hardware as the single biggest reason to buy if you need a ready-to-install replacement that covers both #35 and #40\/41\/420 chain setups.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement:\u003c\/strong\u003e Fits Comet TAV2 models 218353A, 219552A, 219456A and 217610A so installation follows existing mounting points on most karts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4 in shaft compatibility:\u003c\/strong\u003e Works with engines that have a 3\/4 in straight crankshaft and covers common small engine sizes from 2 hp to 8 hp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual sprocket kit:\u003c\/strong\u003e Includes both a 12 tooth sprocket for #35 chain and a 10 tooth sprocket for #40\/41\/420 chain so you can adapt to different rear axle or chain standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt and cover included:\u003c\/strong\u003e The kit ships with a drive belt (approx 27.76 in length), a plastic assembly cover and an aluminum mounting plate for a more complete installation than clutch-only replacements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30 series asymmetrical design:\u003c\/strong\u003e The CVT clutch geometry is intended to reduce engine load and provide smoother takeoff and improved speed range compared with a simple centrifugal clutch.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis torque converter kit is aimed at do-it-yourself mechanics and kart owners running live-axle go-karts, mini-bikes, or other small machines that use a TAV2 style torque converter and a 3\/4 in shaft. It is particularly useful when rear tires are larger than 16 in and a centrifugal clutch cannot reliably deliver the required traction or speed range.\u003c\/p\u003e\u003cp\u003eThose who should look elsewhere include riders needing a sealed OEM Comet unit by original manufacturer branding or people with crankshafts that are not 3\/4 in straight shafts.

It delivers strong practical value thanks to the included sprockets, belt and mounting hardware, and fits the common 2 hp to 8 hp engines used on many karts. Buy this if you need a complete, direct-fit CVT swap and are comfortable with an aftermarket reproduction rather than an OEM-branded unit.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWill this fit my engine?\u003c\/strong\u003e\u003cbr\u003eThis fits engines with a 3\/4 in straight crankshaft and is intended for engines from about 2 hp to 8 hp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit include sprockets for different chains?\u003c\/strong\u003e\u003cbr\u003eYes, it includes a 12 tooth sprocket for #35 chain and a 10 tooth sprocket for #40\/41\/420 chain; chain is not included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the original Comet part?\u003c\/strong\u003e\u003cbr\u003eNo, this is an aftermarket reproduction that is compatible with Comet TAV2 units but not manufactured by Comet.\u003c\/p\u003e","brand":"MOOSUN","offers":[{"title":"Default Title","offer_id":48202133471451,"sku":"B07T1KRS4V","price":54.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/1043\/1707\/files\/516UsAZ6O9S._AC.jpg?v=1770275873","url":"https:\/\/gearmusthave.com\/products\/go-kart-torque-converter-cvt-clutch-3-4-in-tav2-replacement-smooth","provider":"GearMustHave","version":"1.0","type":"link"}
