Replacing the large spider plate restores proper blade seating and rotor balance, making this a critical part for any technician performing a trowel overhaul or responding to uneven blade wear and vibration complaints.\u003c\/p\u003e\u003cp\u003eNo specific torque values or installation intervals were available in the referenced manual for this part, but as a high-wear rotary component subject to continuous impact and lateral stress during concrete finishing operations, it should be inspected at every major service interval and replaced immediately upon any sign of cracking, deformation, or blade-mount looseness. Using a genuine OEM spider plate ensures correct blade arm geometry and proper fit with the rotor assembly, which directly affects finish quality and operator safety.\u003c\/p\u003e\u003cp\u003eCompatible with the following Bartell Global walk behind trowel models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eB446\u003c\/li\u003e\n\u003cli\u003eB446 MEGA-T\u003c\/li\u003e\n\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":43412751843376,"sku":"10820","price":495.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/10820.jpg?v=1784313137","url":"https:\/\/cce-industries.com\/products\/bartell-10820-spider-plate-large-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
