A worn or damaged pulley can cause accelerated belt wear, loss of trowel blade speed, vibration, and uneven finishing performance, all signs that this component should be inspected and replaced during routine drivetrain servicing. When installing, ensure the bore is properly seated and secured on the shaft to prevent lateral movement under load. Verify belt alignment after installation and inspect belt tension, as an incorrectly tensioned belt running on a new pulley will cause premature wear to both components. Always inspect the mating belt for wear before reinstalling, as a worn belt on a new pulley will degrade performance and shorten service life.\u003c\/p\u003e\u003cp\u003eCompatible with the following Bartell walk behind trowel models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eB424\u003c\/li\u003e\n\u003cli\u003eB430\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":43412754399280,"sku":"11685","price":181.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/11685.jpg?v=1784313426","url":"https:\/\/cce-industries.com\/products\/bartell-11685-pulley-4-5-dia-x-3-4-bore-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
