It is a \u003cstrong\u003e12-rib belt, 64.0 in long and 1.68 in wide\u003c\/strong\u003e, specified for \u003cstrong\u003e2011-2013 Mack CHU and CXU\u003c\/strong\u003e tractors and \u003cstrong\u003eVolvo VNL 660, 670 Gen 2, 730 and 780\u003c\/strong\u003e applications. A belt this wide is doing serious work, and when it goes glazed or cracked you hear it first as a squeal and feel it next as accessories dropping out one by one. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eTwelve Ribs of Bite: The Conti Extreme Poly-V Advantage\u003c\/h2\u003e\n\n\u003cp\u003eTwelve ribs across \u003cstrong\u003e1.68 in of belt width\u003c\/strong\u003e is a lot of seating surface, and that is the point. Spreading the drive load across twelve grooves instead of a handful keeps contact pressure per rib low, which is what stops a heavily loaded accessory drive from polishing its own belt smooth and then slipping every time the load steps up. The \u003cstrong\u003eConti Extreme\u003c\/strong\u003e construction is built for exactly that duty - the long, hot, high-mileage running that a Class 8 tractor does for a living.\u003c\/p\u003e\n\n\u003cp\u003eLength is the deciding spec on any serpentine belt. At \u003cstrong\u003e64.0 in\u003c\/strong\u003e, this belt is cut for the drives it is listed against, which puts the automatic tensioner in the middle of its travel instead of at the end of its range with nothing left for stretch. The belt weighs 0.6 lbs and ships in a 16 x 6 x 1 in carton, so it is an easy and inexpensive spare to carry.\u003c\/p\u003e\n\n\u003cp\u003eAt FleetPro Parts \u0026amp; Tires, we know a belt failure is never just a belt. This Conti Extreme belt is a direct replacement for highly searched industry numbers including \u003cstrong\u003eContitech 4120640X\u003c\/strong\u003e and 4120640, and \u003cstrong\u003eGates K120640\u003c\/strong\u003e and K120640HD. Check the tensioner condition at every belt change, because a fresh belt on a tired tensioner will chirp and wear out on the same schedule as the one you removed.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis Conti Extreme Poly-V belt is intended for the following commercial applications:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e 2011-2013 Mack CHU, CXU612 and 613\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e Volvo VNL 660, 670 Gen 2, 730 and 780\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBelt Path:\u003c\/strong\u003e 12-rib poly-V accessory drive, 64.0 in loop\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Group:\u003c\/strong\u003e Engine \/ Belts \u0026amp; Tensioners\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis Continental serpentine belt serves as a direct replacement for the following part numbers:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eContitech Interchange:\u003c\/strong\u003e 4120640X, 4120640\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGates Interchange:\u003c\/strong\u003e K120640, K120640HD\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomann Distributor #:\u003c\/strong\u003e 815.4120640X\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Conti Extreme Poly-V serpentine belt\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRibs:\u003c\/strong\u003e 12\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 64.0 in\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 1.68 in\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.6 lbs\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePackage Dims:\u003c\/strong\u003e 16 x 6 x 1 in\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 889626420368\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-Year FleetPro Warranty\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Level:\u003c\/strong\u003e OEM\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Continental (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Continental","offers":[{"title":"Default Title","offer_id":43024031350855,"sku":"815.4120640X","price":29.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/image_1920_e8ee42c7-eb32-4537-a0af-c9129ced055e.jpg?v=1785427781","url":"https:\/\/fleetpropt.com\/products\/continental-conti-extreme-poly-v-belt-12-rib-64-in-mack-chu-cxu-volvo-vnl-4120640x-k120640-815-4120640x","provider":"FLEETPRO PARTS \u0026 TIRES ","version":"1.0","type":"link"}
