The Chelsea 880XGAKX-M6XK or 880XGAKXM6XK is an 880 Series Power Take-Off assembly built for heavy-duty applications on 8-bolt manual transmissions compatible with Volvo/Mack, Allison, Eaton/Fuller, and other transmission families. It uses lever mechanical shift and delivers output through a 1-1/2"-10 spline shaft fitted with a 1410 companion flange. Shaft power reaches 48 HP at 500 RPM and 95 HP at 1000 RPM, with an intermittent torque rating of up to 500 lb-ft (check application pages for actual ratings). The cast iron housing stands up to demanding service in bulk hauling, fire truck, oil field, aerial, and large truck recovery applications. Call us to confirm proper fit for your specific transmission.

The Chelsea 880 Series is designed for high-torque, high and low speed applications with constant mesh input gears. Tapered cone bearings provide excellent load-bearing capability. Typical applications include bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large truck recovery vehicles. The 880 Series also supports markets including oil and gas, mining, aerial, and on-highway vehicle use.
