The Chelsea 288 Series Power Take-Off, part number 288GDFJP-M8RY or 288GDFJPM8RY, is a 10-bolt constant mesh PTO built for heavy-duty continuous operation. It delivers a continuous duty torque rating of up to 390 lb-ft and is offered in nine speed ratios covering both low and high speed ranges. Ductile iron bearing caps replace the gray iron used in the predecessor 287 Series, providing 117% greater strength. An O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The standard output shaft features a positive stop design that prevents oil seal damage from driveline couplings. A wet spline lubrication option is available, extending pump shaft life by 7 to 10 times over standard configurations. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 288 Series is suited for demanding vocational applications including snow and ice control, vacuum, aerial, and refuse equipment. The wet spline option routes a fresh, clean flow of oil through the PTO and pump shaft to prevent premature spline fretting. The O-ring sealing configuration specifically addresses vibrational stress introduced by current and future engine designs. This unit is also referenced under part number SP288GDFJP-M8RY in some catalog systems.
