The Chelsea 288GMFJW-M5RY or 288GMFJWM5RY is a heavy-duty, constant mesh power take-off assembly from the 288 Series, built on a 10-bolt mounting platform. The cast iron housing and ductile iron bearing caps, rated 117% stronger than gray iron, are designed to handle the vibrational demands of modern engine designs. An O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. The output shaft features positive stop for driveline outputs, which eliminates oil seal damage from shaft couplings. The Wet Spline lubrication option extends pump shaft life by 7 to 10 times compared to standard configurations. Nine speed ratios spanning both low and high ranges give this unit broad application flexibility across snow and ice, vacuum, aerial, and refuse truck markets. A hose is included, so no separate order is needed. Call us to confirm proper fit for your application.
