The Chelsea 880 Series Power Take-Off Assembly, part number 880XRAHX-A5XY or 880XRAHXA5XY, is an 8-bolt PTO built for high-torque, heavy-duty applications. It delivers up to 500 lb-ft intermittent torque and produces 48 HP at 500 RPM and 95 HP at 1,000 RPM. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange. Shift is lever mechanical. Compatible transmissions span Volvo/Mack, Allison, Eaton/Fuller, and other manufacturers. The cast iron housing and removable shift cover make backlash adjustment straightforward during installation. Typical applications include bulk haulers, fire trucks, oil field equipment, winch rigs, and large truck recovery vehicles. Call us to confirm proper fit for your specific transmission.
The Chelsea 880 Series fits most manual transmissions with an 8-bolt aperture and is suited for bulk haulers, fire trucks, aerial equipment, oil field rigs, winch applications, and large truck recovery. The series offers output options including SAE B, SAE C, and ISO 7652 pump flanges in addition to driveline configurations. Constant mesh input gears support both high and low speed operation. Tapered cone bearings provide load-bearing capability for sustained heavy-duty service. Continuous operation is supported with a 30% de-rating applied.
