Technicians should inspect bearings whenever the drive gear assembly is opened, and replace immediately if any roughness, play, or noise is detected during rotation. When reinstalling, ensure the bearing housing is clean and free of debris, and that the bearing is seated fully and squarely before reassembly to avoid premature failure. Proper lubrication and torque on all surrounding fasteners, such as the M8 cap head socket screws used in comparable Bartell drive gear assemblies, are essential to maximizing service life.\u003c\/p\u003e\u003cp\u003eThis bearing is compatible with the following Bartell Global walk behind trowel models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBC436\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":43412763508784,"sku":"21786","price":62.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21786.jpg?v=1784314280","url":"https:\/\/cce-industries.com\/products\/bartell-21786-bearing-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
