The Chelsea 880 Series Power Take-Off Assembly, part number 880XGAHX-M3XK or 880XGAHXM3XK, is an 8-bolt, lever mechanical shift PTO built for high-torque, heavy-duty applications. It features a 1-1/2"-10T spline output shaft with a 1410 companion flange and is rated for intermittent torque in the 401-500 lb-ft range (check application pages for your specific rating). Shaft power is 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other major transmission families. The cast iron housing supports dual-pump output, allowing a hydraulic pump to be mounted on each end. A removable shift cover makes backlash adjustment straightforward during installation. Call us to confirm proper fit for your transmission and application.
The Chelsea 880 Series PTO is designed for demanding on-highway and off-highway service, including bulk haulers, fire trucks, oil field equipment, aerial units, winch applications, and large truck recovery. The 880 Series supports continuous operation with a 30% de-rating. Tapered cone bearings provide load-bearing capability suited to high-torque, variable-speed use. The series is available for a wide range of transmissions, including the Eaton Endurant. Constant mesh input gears support both high- and low-speed operation.
