The Chelsea 880 Series Power Take-Off Assembly, part number 880XBAKP-H4XK or 880XBAKPH4XK, is an 8-bolt, lever mechanical shift PTO built for high-torque, heavy-duty applications. Output is through a 1-1/2"-10 spline shaft with a 1410 companion flange, rated at up to 500 lb-ft intermittent torque (678 Nm). Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1,000 RPM. The 880 Series fits most manual transmissions with an 8-bolt aperture, including Eaton/Fuller, Volvo/Mack, and Allison, and is suited for bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. A cast iron housing and constant mesh input gears support demanding duty cycles. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series is suited for oil and gas, aerial, mining, on-highway, and other mobile applications.
