A compromised arm causes the power trowel to bounce and vibrate, particularly at high speed, and results in an uneven surface finish due to blades sitting out of level with one another. When an arm cannot be returned to its original straight condition, replacement with a new OEM part is required.\u003c\/p\u003e\u003cp\u003eDuring installation, the trowel arm adjustment screw must never protrude below the underside surface of the arm. If it is not flush, blade-level issues will persist regardless of other adjustments. The lift lever is reinstalled onto the replacement arm by threading the set screw and securing with the jam nut. Final blade-level verification using the Bartell trowel arm adjustment fixture (Part #20801) is recommended after any arm replacement.\u003c\/p\u003e\u003cp\u003eCompatible with the following Bartell Global walk-behind trowel models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBC446\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":43412764098608,"sku":"21833","price":114.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21833.jpg?v=1784314347","url":"https:\/\/cce-industries.com\/products\/bartell-21833-trowel-arm-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
