The Chelsea 680 Series Power Take-Off Assembly, part number 680XFAHX-P5GZ or 680XFAHXP5GZ, is a medium-to-heavy-duty 8-bolt PTO built for higher-torque applications including pneumatic blowers. It shifts via wire/cable mechanical actuation and features a 1-1/4" round output shaft with keyway. Intermittent torque capacity is rated at up to 375 lb-ft (508 Nm) -- verify against Chelsea application pages for your specific configuration. The cast iron housing runs tapered cone bearings on both the output and input shafts for greater load-bearing capability versus needle-bearing designs. A deep-mount housing option makes this unit compatible with Mack transmission applications, and the series covers Eaton/Fuller as well. Shaft power output reaches 107 HP at 1,500 RPM.
