The Chelsea 680 Series Power Take-Off, part number 680ZQDAX-A5XV or 680ZQDAXA5XV, is a medium- to heavy-duty 8-bolt PTO built for higher-torque applications including pneumatic blowers, dump trucks, and refuse equipment. It features a cast iron housing with tapered cone bearings on the output shaft for extended service life, and the input shaft uses tapered bearings rather than needle bearings for greater load capacity. The 1-1/4" round output shaft with key suits a range of pump and driveline configurations. Shift is mechanical via wire/cable. Intermittent torque rating for the 680 Series runs 375 lb-ft (508 Nm); verify the exact rating for this configuration on Chelsea's application pages. Shaft power at 1,000 RPM is 71 HP (53 kW). A deep-mount housing option makes it compatible with Mack transmissions. Call us to confirm proper fit for your specific transmission.
