878XDFJP-M5XV Chelsea PTO Assembly

The Chelsea 878XDFJP-M5XV or 878XDFJPM5XV is a 878 Series constant mesh Power Take-Off engineered to mount on Allison and CAT 10-bolt transmissions. Built around a cast iron housing with a ductile iron bearing cap rated 117% stronger than gray iron, this PTO handles continuous and intermittent duty without a separate torque derating. The 878 Series delivers up to 670 lb-ft of torque in the smallest package available for this class, with nine available speed ratios spanning low and high ranges. Rotatable cast iron flanges reduce interference clearance issues, and the wet spline lubrication option extends shaft service life by 7 to 10 times compared to a dry spline configuration. A hose is included. Call us to confirm proper fit for your application.
