This is the genuine OEM replacement trowel arm for Bartell walk-behind trowels, designed to restore correct blade geometry and smooth machine operation.\u003c\/p\u003e\u003cp\u003eDuring service, trowel arms should be inspected for bending and either straightened or replaced. This part is designed for use with the Bartell trowel arm adjustment fixture (Part #20801), which accommodates both left-hand and right-hand arm configurations. When reinstalling, the trowel arm adjustment screw must never protrude below the underside surface of the arm, if it is not flush, blade level will be compromised and bouncing or uneven finishing will result. The lift lever attaches to the arm via a square head set screw and jam nut, which must be loosened before removal and re-torqued securely on installation. The adjustment bar on fixture #20801 should be set to 36\" when servicing arms for the BC436.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBartell BC436\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412763836464,"sku":"21812","price":91.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21812.jpg?v=1784314318","url":"https:\/\/cce-industries.com\/products\/bartell-21812-trowel-arm-oem-walk-behind-trowel-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
