The Chelsea 878XEFJP-M5RS or 878XEFJPM5RS is a constant-mesh Power Take-Off from Chelsea's 878 Series, engineered to mount on Allison and CAT 10-bolt transmissions. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. Rotatable cast-iron flanges cut interference clearance issues, and the Positive Stop design on driveline outputs eliminates oil seal damage from coupling contact. The Wet Spline Lubrication option delivers 7 to 10 times greater output shaft life. Nine speed ratios spanning low and high ranges give this unit broad application coverage across refuse, vacuum, aerial, and snow-and-ice equipment. A hydraulic hose is included. Call us to confirm proper fit for your specific transmission configuration.
