If you see a blue or purple discoloration along the steel casing, the metal has overheated, losing its structural temper and warping out of round. A warped bell will instantly ruin a brand new set of clutch shoes.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eInstallation Tip:\u003cstrong\u003e Before sliding this new clutch bell onto the rear pulley shaft, use a bit of brake cleaner on a clean rag to wipe down the inside friction track. Factory parts are shipped with a micro-thin layer of anti-rust oil that must be removed so your clutch pads don’t instantly glaze over on the first ride.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003ePro Tip:\u003cstrong\u003e If your scooter’s transmission feels sluggish from a dead stop, changing the clutch bell is only half the battle. Take this opportunity to check the thickness of your clutch friction pads. If they are worn down near the backing plates, swapping in a matching performance or OEM replacement clutch assembly will guarantee that snappy, off-the-line launch power.\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e \u003ca href=\"https:\/\/www.P65Warnings.ca.gov\" target=\"_blank\" title=\"California Proposition 65\" rel=\"noopener\"\u003eCalifornia Proposition 65\u003c\/a\u003e \u003c\/p\u003e","brand":"RMS","offers":[{"title":"Default Title","offer_id":50895815868696,"sku":"82517R-AFT","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0782\/1728\/1816\/files\/82517R-AFT.webp?v=1771965463","url":"https:\/\/www.scooterworks.com\/products\/clutch-bell-vespa-gts-250-300-82517r-aft","provider":"Scooterworks USA, LLC","version":"1.0","type":"link"}
