When this ring fails or becomes deformed, adjacent components lose their positional retention, leading to accelerated wear, misalignment, and potential mechanical failure during operation.\u003c\/p\u003e\u003cp\u003eDesigned to seat precisely into an external groove on a shaft or pin, this ring provides a reliable, low-profile shoulder that keeps assemblies properly located without the need for threaded fasteners. On ride-on trowels, these rings are commonly found in drivetrain, blade pitch, and linkage assemblies where compact retention solutions are essential. Technicians should inspect retaining rings any time a related assembly is disassembled, replacing any ring that shows signs of distortion, corrosion, or loss of spring tension. Always use the correct retaining ring pliers to install and remove this part safely and without damage to the groove.\u003c\/p\u003e\u003cp\u003eThis part is compatible with the following Bartell Global models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBXR836HYD\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":43412761542704,"sku":"21712","price":36.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21712.jpg?v=1784314169","url":"https:\/\/cce-industries.com\/products\/bartell-21712-external-retaining-ring-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
