The Chelsea 680XQAHX-A5XR is a 680 Series Power Take-Off designed for manual transmissions with an 8-bolt PTO aperture. The 680 Series is a medium-to-heavy-duty PTO well suited for Eaton Fuller transmissions, with a deep-mount housing option for Mack applications. Cast iron construction and tapered cone bearings on the output shaft give this series a high intermittent torque rating and long service life. Shift options include wire/cable and mechanical actuation. Output configurations span SAE A, SAE B, and SAE C pump flanges as well as driveline outputs, making it adaptable to a wide range of hydraulic and pneumatic-blower installations.
