The Chelsea 880XRAHX-P5AZ is an 880 Series Power Take-Off designed for 8-bolt manual transmission apertures. The 880 Series features constant mesh input gears and is rated for up to 500 lb-ft of intermittent torque, making it a proven choice for bulk haulers, fire trucks, oil field equipment, aerial units, winch applications, and large recovery trucks. Shift is lever/mechanical, with an optional air control shift available for the series. A rugged cast iron housing and tapered cone bearings handle demanding, high-torque duty cycles. The removable shift cover simplifies backlash adjustment during installation. Output options across the series include SAE B, SAE C, and ISO 7652 pump flanges as well as driveline configurations.
