The Chelsea 878 Series Power Take-Off Assembly, part number 878LEFJW-M5TY or 878LEFJWM5TY, is a constant mesh PTO engineered for Allison 10-bolt transmissions. The 878 Series builds on the proven 877 Series platform with 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 a cast iron housing. The series is rated up to 670 lb-ft of torque in both intermittent and continuous duty applications. Rotatable cast iron flanges reduce clearance and interference issues, and a Wet Spline Lubrication option extends shaft life by 7 to 10 times. The hose is included. Call us to confirm proper fit for your application.
