The Chelsea 288 Series Power Take-Off Assembly, part number 288GSFJP-M5AC or 288GSFJPM5AC, is a 10-bolt constant mesh PTO built on the 281 Series platform. It delivers a single, continuous duty torque rating of up to 390 lb-ft, supported by wider gears and larger capacity bearings. Ductile iron bearing caps are 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration damage from modern engine designs. Nine speed ratios cover both low and high speed applications. The standard output shaft includes a positive stop feature that eliminates oil seal damage from shaft couplings. A Wet Spline Lubrication option extends pump shaft life by 7 to 10 times. The 288 Series replaces the Chelsea 287 Series PTO. Call us to confirm proper fit for your application.
