It has two distinct jobs. It smooths the power delivery of a single cylinder engine, which fires only once every two revolutions and would otherwise deliver drive in pulses, and it provides the mounting and pivot points that let the shoes fly outward under centrifugal force to engage the clutch bell.\u003c\/p\u003e\u003cp\u003eFlywheels wear at the shoe pivots and can develop cracks around the taper where they clamp to the crankshaft. Both are serious. A flywheel that has worn at the pivots lets the shoes sit unevenly, so the clutch engages inconsistently and the car becomes unpredictable on corner exit. A crack at the taper risks the whole assembly working loose on the crank, which destroys the crankshaft.\u003c\/p\u003e\u003cp\u003eNote that 3PC in Kyosho's naming refers to the three-shoe clutch type this flywheel is built for, not a pack quantity. It pairs with the IF476 flywheel nut.\u003c\/p\u003e","brand":"PowerHobby","offers":[{"title":"Default Title","offer_id":44532858978392,"sku":"KYOIF432","price":16.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0567\/0554\/8376\/files\/kyoif432_1f4a6192-707b-4fdf-b8ea-cb3b9ea07b53.jpg?v=1786242899","url":"https:\/\/beavertonmilestonehobby.com\/products\/kyosho-if432-32mm-3-shoe-flywheel-inferno-mp9","provider":"Beaverton Milestone Hobby","version":"1.0","type":"link"}
