It is intentionally the weakest link in the chain. It takes up small misalignments and absorbs the shock of starting, and it wears out over time so that the shafts and bearings on either side of it do not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA tired insert makes noise before it fails outright, usually a rattle or a knock that rises and falls with load. Left long enough it lets go completely, and then the motor runs while the pump does nothing. Because the kit is inexpensive next to the parts it protects, it is worth changing at the first sign of wear rather than waiting.\u003c\/p\u003e\u003cp\u003eThis is the Raypak part, number 015285F, built from durable materials and intended as a routine service item.\u003c\/p\u003e","brand":"Raypak","offers":[{"title":"Default Title","offer_id":48628951646420,"sku":"RAY-151-9554","price":111.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_78c7d9b5-5735-4151-ac73-d90266ab5a3f.png?v=1788758432","url":"https:\/\/www.activepoolsupply.com\/products\/raypak-015285f-4j-pump-coupler-insert-taco-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
