It is the genuine Polaris part, supplied complete rather than as separate pieces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy a sprocket matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA pressure side cleaner earns its keep by covering the whole pool on a repeatable pattern. Everything in the drive train has to hand power along cleanly for that to happen. When sprocket teeth round off or chip, drive slips instead of transferring, and the cleaner ends up running hard while moving slowly and skipping parts of the floor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTake the sprocket out and look at the teeth against a good one. Rounded, cracked or missing teeth are the confirmation. It is also worth checking the rest of the drive train while the cleaner is open, since a sprocket rarely wears in isolation.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48629185249492,"sku":"R0547500","price":25.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_efcf1123-032a-47f3-a602-885e8e4e5543.jpg?v=1788760075","url":"https:\/\/www.activepoolsupply.com\/products\/3900-drive-sprocket-assembly","provider":"Active Pool Supply","version":"1.0","type":"link"}
