The Chelsea 878XCFJW-M3RZ or 878XCFJWM3RZ is a constant-mesh Power Take-Off assembly from the Chelsea 878 Series, designed to fit Allison and CAT 10-bolt transmissions. The 878 Series is Chelsea's improvement on the proven 877 Series platform, featuring 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 steel clutch disc thickness increased 80% over the previous design. Nine speed ratios cover both low and high speed applications. Rotatable cast-iron flanges reduce interference clearance issues, and driveline outputs include a positive stop to eliminate oil seal damage. A genuine Chelsea part sold by Pro Gear and Transmission.
