The Chelsea 880 Series Power Take-Off Assembly, part number 880XJAHX-P5AF or 880XJAHXP5AF, is an 8-bolt PTO built for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. It delivers up to 500 lb-ft intermittent torque and 95 HP at 1,000 RPM via a 1-1/2"-10T spline output shaft with a 1410 companion flange. The lever mechanical shift keeps the installation straightforward, and the removable shift cover simplifies backlash adjustment. Cast iron housing and tapered cone bearings handle the sustained loads common in winch and blower applications. Compatible with a wide range of transmissions including Eaton/Fuller, Allison, and Volvo/Mack. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 880 Series is suited for oil and gas, aerial, mining, on-highway, and other mobile applications. Typical uses include bulk haulers, winch systems, fire trucks, oil field equipment, aerial platforms, and large truck recovery. The 880 Series supports continuous operation with a 30% de-rating and is available with pressure lube (P) or no pressure lube (X) configurations. Tapered cone bearings provide strong load-bearing performance under high-torque, variable-speed conditions.
