The Chelsea 281 Series Power Take-Off, part number 281GGFJW-G5RK or 281GGFJWG5RK, is a hydraulically shifted (PowerShift) hot-shift PTO designed for automatic transmissions with a 10-bolt aperture, most commonly Allison and Caterpillar transmissions. It carries a continuous torque rating of 390 lb-ft and delivers output options that include SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline configurations. The 281 Series is an evolution of the 280 Series, featuring a ductile iron bearing cap 117% stronger than gray iron, an enhanced clutch pack with 80% thicker steel discs, and nine available speed ratios spanning low and high ranges. Common markets include fire and rescue, truck cranes, refuse, and pumper cleaner equipment. Call us to confirm proper fit for your specific transmission and application.
