The Chelsea 288GMFJP-M8RK or 288GMFJPM8RK is a heavy-duty, 10-bolt constant mesh power take-off built on the proven 288 Series platform. This PTO delivers a continuous duty torque rating of up to 390 lb-ft and mounts via a 10-bolt pattern, with a round output shaft featuring a 1-1/4" key. Ductile iron bearing caps are 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration damage and improves clamp load. Nine speed ratios cover both low and high speeds. Rotatable cast-iron flanges reduce interference clearance issues, and a positive-stop output protects oil seals from shaft coupling damage. Wet Spline lubrication is available to extend pump shaft life by 7 to 10 times. The 288 Series replaces the Chelsea 287 Series. Call us to confirm proper fit for your application.
