The Chelsea 878XAKVW-M5RF or 878XAKVWM5RF is a constant mesh Power Take-Off assembly from the Chelsea 878 Series, engineered to fit Allison and CAT 10-bolt transmissions. The 878 Series delivers up to 670 lb-ft of continuous torque in a compact package, with nine available speed ratios covering both low and high speed ranges. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap improve clamp load and reduce vibration-related damage. Rotatable, cast-iron flanges reduce interference clearance issues, and driveline outputs include a positive stop to prevent oil seal damage. The Wet Spline Lubrication option extends shaft life 7 to 10 times over standard configurations. A hydraulic hose is included. Call us to confirm proper fit for your application.
