The Chelsea 288 Series Power Take-Off Assembly, part number 288GGFJW-M3RY or 288GGFJWM3RY, is a heavy-duty 10-bolt constant mesh PTO built on the proven 281 Series platform. The 288 Series carries a continuous duty torque rating of up to 390 lb-ft and features a round shaft output with a 1-inch, 1/4-inch key configuration. Nine speed ratios cover both low and high speed demands. Ductile iron bearing caps deliver 117% greater strength over gray iron, and an O-ring seal between the housing and bearing cap improves clamp load while reducing vibration-related damage. The rotatable cast-iron flanges reduce interference clearance issues. Wet Spline lubrication extends pump shaft life by 7 to 10 times. The hose ships with the unit. Common market applications for this series include refuse, vacuum, aerial, and snow and ice equipment. Call us to confirm proper fit for your application.
