Built from iron for heat dissipation and wear resistance, it accepts a 3\/4\" shaft with a 3\/16\" keyway and mates to #35 chain sprockets via its 12-tooth profile. The package includes mounting hardware so you can install it on many hobby and light utility builds without hunting down extra bolts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Vashly clutch engage and protect the engine on startup?\u003c\/h3\u003e\n\u003cp\u003eThe Vashly clutch uses centrifugal shoes that move outward as engine speed rises, engaging the drum and pulling the sprocket to turn the chain only after rpm passes the engagement threshold. That gradual engagement reduces shock loads to the crank and drivetrain compared with direct coupling. It also helps the engine idle without driving the wheels, useful for stalling prevention and smooth low-speed operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e12-tooth drum designed for #35 chain compatibility\u003c\/li\u003e\n  \u003cli\u003eCentrifugal engagement smooths load transfer during acceleration\u003c\/li\u003e\n  \u003cli\u003eAllows engine to idle without propelling the machine\u003c\/li\u003e\n  \u003cli\u003eIron construction helps dissipate heat from slipping or repeated engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and machines will this clutch fit?\u003c\/h3\u003e\n\u003cp\u003eThis clutch fits engines with a 3\/4\" crank shaft and a 3\/16\" keyway, including many common small engines and clone units. It’s commonly used on Predator 212cc conversions, Honda GX160\/GX200\/GX140\/GX120 series, many 5.5–6.5 HP clone motors, and several Briggs\/Tecumseh variants. Always verify shaft diameter and keyway before buying to ensure proper fit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with Predator 212 and many clone engines\u003c\/li\u003e\n  \u003cli\u003eFits Honda GX160, GX200, GC160, GC190 and similar models\u003c\/li\u003e\n  \u003cli\u003eWorks with most 4–7 HP motors that use a 3\/4\" shaft and 3\/16\" keyway\u003c\/li\u003e\n  \u003cli\u003eCommonly used on go-karts, minibikes, hand-built fun karts and small utility rigs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat hardware and build quality does the clutch include?\u003c\/h3\u003e\n\u003cp\u003eThe clutch arrives with the mounting bolt set, washers and the necessary Allen wrench, so you can mount it immediately without sourcing extra fasteners. Its iron housing offers improved wear resistance and faster heat dispersion than some low-cost alloys, which helps when the clutch experiences brief slippage during startup or heavy acceleration. The 12 teeth are machined to fit #35 chain sprockets and tolerate routine recreational use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComes with 2 clutch bolts, 2 washer kits and 2 screw wrenches included\u003c\/li\u003e\n  \u003cli\u003eIron construction for improved durability and heat dissipation\u003c\/li\u003e\n  \u003cli\u003e12-tooth profile milled for standard #35 chain mesh\u003c\/li\u003e\n  \u003cli\u003eSupplied hardware makes installation straightforward\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I check fit and maintain the centrifugal clutch for longevity?\u003c\/h3\u003e\n\u003cp\u003eBefore installing, measure your engine’s crank shaft diameter and keyway size to confirm a 3\/4\" shaft with a 3\/16\" keyway. During break-in and early use, avoid prolonged slipping and check mounting bolts and chain alignment regularly. Periodic inspection of the shoes and drum for glazing or wear keeps engagement consistent and extends service life.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVerify 3\/4\" shaft and 3\/16\" keyway before purchase\u003c\/li\u003e\n  \u003cli\u003eEnsure chain alignment and proper tension after installation\u003c\/li\u003e\n  \u003cli\u003eInspect shoes\/drum for glazing or overheating signs every few rides\u003c\/li\u003e\n  \u003cli\u003eRetighten mounting hardware after initial run-in and periodically thereafter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Vashly 12T 3\/4\" bore centrifugal clutch is aimed at hobbyists, fabricators and small-engine modifiers building or repairing go-karts, minibikes, pocket bikes and light utility machines. It’s a practical choice for anyone adapting horizontal shaft engines (Predator, Honda clones and similar) to a #35 chain drive who wants a simple, bolt-on clutch with included hardware. If you need a different bore, tooth count, or a clutch rated for heavy industrial loads, choose a model designed specifically for those requirements.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this clutch fit a Predator 212 engine?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it commonly fits Predator 212-style horizontal shaft engines that use a 3\/4\" crank shaft and 3\/16\" keyway.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the package include mounting bolts and tools?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the clutch ships with two clutch bolts, two washer kits and screw wrenches for installation.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Vashly","offers":[{"title":"Default Title","offer_id":55167575359831,"sku":"B09FQ34HKW","price":55.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/vashly-clutch-front-view.jpg?v=1790388896","url":"https:\/\/britishgarage.co.uk\/products\/vashly-go-kart-centrifugal-clutch-12t-3-4-bore-for-35-chain-iron-includes-mounting-hardware","provider":"British Garage","version":"1.0","type":"link"}
