The Chelsea 880GRAHX-V5XS or 880GRAHXV5XS is an 880 Series Power Take-Off (PTO) built for heavy-duty, high-torque applications on 8-bolt manual transmissions. It uses a lever mechanical shift and delivers up to 500 lb-ft (678 Nm) 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. Compatible transmissions include Volvo/Mack, Allison, and Eaton/Fuller platforms. The cast iron housing holds up in oil field, fire truck, bulk hauler, and large recovery truck service. A genuine Chelsea part available from Pro Gear and Transmission.

The Chelsea 880 Series is suited for demanding on-highway and off-highway service including bulk haulers, fire trucks, oil field equipment, aerial units, winch systems, and large truck recovery. The series uses constant mesh input gears for both high and low speed operation, and tapered cone bearings for strong load-bearing performance. The 880 Series is also available for the Eaton Endurant transmission. An optional air control shift is available in addition to the standard lever control.
