The Chelsea 680 Series Power Take-Off Assembly, part number 680XQAHX-V3XY or 680XQAHXV3XY, is a medium- to heavy-duty PTO built for 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. The 680 Series features a cast iron housing with tapered cone bearings on the output shaft, delivering an intermittent torque rating of 375 lb-ft (508 Nm) - check application pages for actual torque ratings for your specific setup. Output shaft is a 1-1/4" round with key. Wire/cable mechanical shift type. Shaft power output reaches 36 HP at 500 RPM, 71 HP at 1000 RPM, and 107 HP at 1500 RPM. A deep-mount housing option accommodates Mack transmission applications. Call us to confirm proper fit for your application.
The Chelsea 680 Series is engineered for vocational applications requiring sustained, higher-torque output - including pneumatic blowers, refuse, aerial, fire and rescue, dump truck, and service truck work. The cast iron housing and tapered bearings on both the input and output shafts contribute to the series' load-bearing capability. Continuous operation is supported with a 30% de-rating. The 680 Series offers multiple output configurations across the broader product line, including SAE A, SAE B, and ISO 7652 pump flanges, various spline options, and a 360-degree rotatable flange for pump fitment flexibility - confirm which output configuration applies to part number 680XQAHX-V3XY for your specific installation. Available as a genuine Chelsea part from Pro Gear and Transmission.
