The Chelsea 880 Series Power Take-Off, part number 880XBITX-A3XK or 880XBITXA3XK, is an 8-bolt, heavy-duty PTO built for high-torque, high- and low-speed applications. It uses a lever-mechanical shift and delivers up to 500 lb-ft intermittent torque, with shaft power rated at 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. Constant mesh input gears and tapered cone bearings handle demanding loads across bulk hauler, fire truck, oil field, aerial, and large truck recovery applications. The removable shift cover simplifies backlash adjustment, and the dual-pump output allows a hydraulic pump to be mounted on each end. Fits most manual transmissions with an 8-bolt aperture. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series is suited for bulk haulers, winch applications, fire trucks, oil field equipment, aerial units, and large truck recovery vehicles. The 880 Series supports continuous operation with a 30% de-rating. Multiple output flange options are available across the series, including SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline configurations. Constant mesh input gears maintain engagement under load. Tapered cone bearings provide load-bearing capacity suited to high-torque intermittent service.
