The Chelsea 880 Series Power Take-Off, part number 880XRDAX-P5AF or 880XRDAXP5AF, is an 8-bolt, lever mechanical shift PTO built for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, rated for intermittent torque in the 401-500 lb-ft range (check Chelsea application pages for the torque rating specific to your transmission pairing). Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing and removable shift cover make backlash adjustment straightforward during installation. Compatible with a broad range of transmissions including Volvo/Mack, Allison, and Eaton/Fuller. Call us to confirm proper fit for your application.
The Chelsea 880 Series is designed for high-torque, high and low speed service with constant mesh input gears and tapered cone bearings for strong load-bearing performance. Typical applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial units, and large truck recovery vehicles. The removable shift cover simplifies backlash adjustment for faster, more accurate installation. The series supports continuous operation with a 30% de-rating. Sold by Pro Gear and Transmission.
