The Chelsea 680 Series Power Take-Off Assembly, part number 680XQAHX-P3AZ or 680XQAHXP3AZ, is built for medium- to heavy-duty applications demanding a high intermittent torque rating in the 301-400 lb-ft range (verify actual rating on the Chelsea application pages). It mounts to 8-bolt transmission openings and uses a wire/cable mechanical shift. The 1-1/4" round output shaft fits a wide range of pump and driveline configurations. A cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft give this unit strong load-bearing capability. The deep mount housing option makes it compatible with Mack transmission applications, and it sees regular use on pneumatic blower trucks, dump trucks, aerial units, and refuse vehicles. Output power exceeds 56 HP, with shaft power ratings of 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. Call us to confirm proper fit for your transmission.
