The Chelsea 680 Series Power Take-Off assembly, part number 680ZSDAX-A5XV or 680ZSDAXA5XV, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. It uses a wire/cable mechanical shift and delivers an intermittent torque rating of 375 lb-ft (508 Nm) - check the Chelsea application pages for your specific installation. The 1-1/4" round output shaft with keyway drives output power of 56+ HP (51+ kW), with shaft power measured at 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. A deep-mount housing option supports Mack transmission applications, and the cast iron housing with tapered cone bearings on the output shaft suits higher-torque work such as pneumatic blower systems. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 680 Series is suited for aerial, dump truck, refuse, fire and rescue, snow and ice removal, service truck, and blower and product pump applications. The cast iron housing and tapered cone bearings on the input and output shafts provide strong load-bearing capability. Chelsea's 360-degree rotatable flange output option (where applicable within the series) gives additional pump placement flexibility. Four internal speed ratios and ten shift options are available across the 680 Series - confirm the correct configuration for your truck by calling Pro Gear and Transmission.
