The Chelsea 680 Series Power Take-Off Assembly, part number 680XQAHX-P3AF or 680XQAHXP3AF, is a medium-to-heavy-duty 8-bolt mount PTO engineered for higher-torque demands including pneumatic blower applications. It mounts to transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers with an 8-bolt PTO aperture, and includes a deep-mount housing option suited for Mack installations. The 1-1/4" round output shaft with keyway delivers wire/cable mechanical shift operation. Intermittent torque capacity spans 301-400 lb-ft (501+ Nm), with shaft power rated at 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. The cast iron housing uses tapered cone bearings on the output shaft and tapered bearings on the input shaft for strong load-bearing capability.
