The Chelsea 878XCFJP-M3RZ is a constant mesh Power Take-Off from the Chelsea 878 Series, built to fit Allison 10-bolt transmissions. The 878 Series delivers up to 670 lb-ft of continuous duty torque, the highest rating available in its package size. Key structural improvements over the predecessor 877 Series include 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 clutch pack steel discs increased 80% in thickness. Rotatable cast iron flanges reduce interference clearance issues, and a positive-stop driveline output protects oil seals. A genuine Chelsea part from Pro Gear and Transmission.
