The Chelsea 288GKFJP-M3RK is a 10-bolt, constant mesh Power Take-Off from the 288 Series heavy-duty platform. The 288 Series delivers a continuous duty torque rating of up to 390 lb-ft and is built on the 281 Series platform with upgrades including ductile iron bearing caps rated 117% stronger than the gray iron caps used in the predecessor 287 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. The round shaft output (1-inch, 1/4-inch key) features a positive stop design that prevents oil seal damage from driveline couplings. Nine speed ratios are available across the 288 Series. Pressure lube and wet spline lubrication are supported. A genuine Chelsea part sold by Pro Gear and Transmission.

Additional Information
The 288 Series is engineered for demanding duty cycles in snow and ice control, vacuum, aerial, and refuse applications. Nine speed ratios are offered across the series, covering both low and high speed requirements. Wet Spline technology routes a continuous flow of clean oil through the PTO and pump shaft, providing up to 7 to 10 times greater shaft life compared to standard configurations. A hose is included with the unit.
