The Chelsea 878XBFJP-M5XV or 878XBFJPM5XV is a constant-mesh Power Take-Off assembly from the Chelsea 878 Series, designed to mount on Allison and CAT 10-bolt transmissions. The 878 Series delivers up to 670 lb-ft of continuous-duty torque in the smallest package available at that rating. A ductile iron bearing cap, 117% stronger than gray iron, anchors the design, while an O-ring sealing configuration between the housing and bearing cap reduces vibration-related wear and improves clamp load. Nine speed ratios cover both low and high ranges. Rotatable cast-iron flanges minimize interference clearance issues on driveline outputs, and the Wet Spline Lubrication option extends shaft life 7 to 10 times compared to standard configurations. Hydraulic hose is included. Call us to confirm proper fit for your application.
