The Chelsea 878 Series Power Take-Off, part number 878LFFJW-M5TF or 878LFFJWM5TF, is a constant mesh PTO designed for Allison 10-bolt transmissions. Built around a ductile iron bearing cap that is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap to reduce vibrational effects and improve clamp load. The cast iron housing features rotatable flanges to minimize interference clearance issues, and driveline outputs include a positive-stop design that eliminates oil seal damage from coupling contact. A wet spline lubrication option extends shaft service life by 7 to 10 times compared to standard dry spline operation. The hose is included, eliminating a separate order. Call us to confirm proper fit for your specific transmission and application.
