The Chelsea 680QHLZX-D3AZ is an 8-bolt Power Take-Off from the Chelsea 680 Series, engineered for medium- to heavy-duty manual transmission applications. The cast iron housing and tapered cone bearings on the output shaft support intermittent torque in the 301-400 lb-ft range, making it well suited to higher-torque work such as pneumatic blowers. Output options include SAE A and SAE B pump flanges, with a space-saving air shift cover for clearance under the truck. Eaton/Fuller and Volvo/Mack transmission compatibility makes the 680 Series one of the most widely applied PTOs in vocational and municipal fleets. Available from Pro Gear and Transmission.
