The Chelsea 880 Series Power Take-Off Assembly, part number 880XTDUX-Y3XV or 880XTDUXY3XV, is an 8-bolt, lever mechanical shift PTO built for heavy-duty on-highway and off-highway work. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, rated for up to 500 lb-ft intermittent torque. Shaft power runs 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible with Volvo/Mack, Allison, and Eaton/Fuller transmissions, among others. The 880 Series fits 8-bolt manual transmission apertures and is suited for applications including bulk haulers, fire trucks, oil field equipment, winch systems, and large truck recovery. The removable shift cover makes backlash adjustment straightforward on installation. Available from Pro Gear and Transmission - call us to confirm proper fit for your transmission and application.
The Chelsea 880 Series is designed for high-torque, high and low speed applications using constant mesh input gears. Tapered cone bearings provide load-bearing capacity suited to bulk haulers, winch systems, fire trucks, oil field equipment, aerial units, and large truck recovery operations. The 880 Series is available for a wide range of manual transmissions with 8-bolt apertures, including Eaton Endurant. Standard shift is lever mechanical; air shift is available as an option. The dual-pump output configuration allows hydraulic pumps to be mounted on both ends of the PTO simultaneously.
