The Chelsea 878XALNP-M5RZ or 878XALNPM5RZ is a constant mesh Power Take-Off from the Chelsea 878 Series, engineered to fit Allison and CAT 10-bolt transmissions. Built around a cast iron housing, this PTO carries a continuous duty torque rating and delivers nine speed ratios spanning low and high speed ranges. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration-related wear. Rotatable cast iron flanges reduce interference clearance issues, and driveline outputs include a positive stop feature that prevents oil seal damage from coupling contact. A hose is included. Call us to confirm proper fit for your specific transmission configuration.
