The Chelsea 288 Series Power Take-Off (PTO) is a heavy-duty, 10-bolt constant mesh unit built for demanding continuous-duty applications including refuse, vacuum, aerial, and snow-and-ice equipment. Part number 288GMFJP-M8RF or 288GMFJPM8RF is built on the 288 Series platform, which delivers a continuous duty torque rating of up to 390 lb-ft and features wider gears with larger-capacity bearings compared to the predecessor 287 Series. The round output shaft with a 1-1/4-inch key includes a positive stop design to protect the oil seal from coupling damage. An O-ring sealing configuration between the housing and bearing cap reduces the vibrational effects of modern engine designs. Nine speed ratios cover both low and high speed requirements. Call us to confirm proper fit for your specific transmission and application.
The 288 Series replaces the Chelsea 287 Series PTO. Key upgrades include ductile iron bearing caps and an improved O-ring sealing configuration designed to address vibrational stress from current and future engine designs. Wet Spline technology circulates a fresh flow of oil through the PTO and pump shaft, preventing premature spline fretting. Rotatable cast-iron flanges reduce interference fit concerns during installation. Applicable markets include refuse, vacuum, aerial, and snow-and-ice truck vocations.
