The Chelsea 878XCFJP-M5RY or 878XCFJPM5RY is a constant mesh Power Take-Off assembly from the Chelsea 878 Series, engineered to fit Allison and CAT 10-bolt transmissions. The 878 Series delivers up to 670 lb-ft of continuous duty torque in the smallest package in its class. Key structural improvements over the previous 877 Series include a ductile iron bearing cap rated 117% stronger than gray iron, an O-ring sealing configuration between the housing and bearing cap for improved clamp load, and rotatable cast-iron flanges that reduce interference clearance issues. A Wet Spline Lubrication option extends shaft life by 7 to 10 times. Nine speed ratios covering both low and high speeds are available within this series. The hydraulic hose is included. Call us to confirm proper fit for your specific transmission and application.
