The Chelsea 880XDAKX-M6XS or 880XDAKXM6XS is an 8-bolt, lever mechanical shift Power Take-Off from Chelsea's 880 Series, built for high-torque, heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large truck recovery rigs. The output shaft is a 1-1/2"-10T spline fitted with a 1410 series companion flange, rated for up to 500 lb-ft of intermittent torque. Shaft power output reaches 48 HP at 500 RPM and 95 HP at 1,000 RPM. The cast iron housing carries constant mesh input gears, and the removable shift cover makes backlash adjustment faster and more accurate during installation. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other 8-bolt aperture manual transmissions. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 880 Series is suited for on-highway and off-highway demanding environments: oil and gas, aerial, mining, fire apparatus, and large recovery trucks. The 880 series uses constant mesh input gears and tapered cone bearings for strong load-bearing performance. Backlash adjustment is simplified by the removable shift cover. The dual-pump output configuration supports mounting a hydraulic pump on each end of the PTO, making this series a practical choice for multi-circuit hydraulic systems on bulk haulers, winch trucks, and similar equipment.
