Worn or cracked spider plates can cause excessive vibration, uneven blade loading, and accelerated wear on surrounding drivetrain components. Replacement is recommended any time visible cracking, deformation, or play in the blade arm mounting points is observed during routine inspection. When installing the replacement assembly, ensure all blade arm attachment points are clean and free of debris before seating the new unit, and verify correct torque on all fasteners per the B424 service manual specifications.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBartell B424 Walk Behind Power Trowel\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":43412761509936,"sku":"21616","price":769.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21616.jpg?v=1784314165","url":"https:\/\/cce-industries.com\/products\/bartell-21616-spider-plate-assembly-oem-replacement-part-walk-behind","provider":"CCE Industries","version":"1.0","type":"link"}
