281GGFJP-D5XV Chelsea PTO Assembly

The Chelsea 281GGFJP-D5XV or 281GGFJPD5XV is a genuine Chelsea 281 Series Power Take-Off assembly designed for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar applications. The 281 Series uses PowerShift hydraulic engagement for hot-shift operation, allowing engagement and disengagement without stopping the transmission. The series carries a continuous torque rating of 390 lb-ft and supports continuous operation duty cycles. Output options within the series include SAE B and SAE C pump flanges and driveline configurations. The ductile iron bearing cap is 117% stronger than gray iron, and the clutch pack features steel discs 80% thicker than the predecessor 280 Series design.

Additional Information

The Chelsea 281 Series is an evolution of the 280 Series PTO, with three key structural upgrades: a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce vibration, and clutch pack steel discs increased 80% in thickness to resist premature tooth wear. The series supports nine speed ratios including both low- and high-speed ranges, and offers an optional SmartStart feature to reduce shock load at engagement. Electronic Overspeed Control (EOC) is available to protect driven equipment. Typical market applications include fire and rescue, truck cranes, pumper-cleaner trucks, and refuse vehicles. Reference documents for the 281 Series include the 281/288 Series Parts List (HY25-2281-M1/US) and the 267/281/288/871/878 Series Owner's Manual.
