The Chelsea 281GDFJP-D5RY is a PowerShift (hydraulic) hot-shift power take-off assembly from the Chelsea 281 Series, designed for 10-bolt aperture automatic transmissions commonly used with Allison applications. The 281 Series is an evolution of the 280 Series platform, featuring a ductile iron bearing cap rated 117% stronger than the gray iron predecessor, an o-ring sealing configuration between the housing and bearing cap for improved clamp load, and clutch pack steel discs increased 80% in thickness to resist premature wear. Continuous torque for the series is 390 lb-ft. Output options across the series include SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline. Applications span fire and rescue, refuse, truck cranes, and pumper/cleaner trucks. Call us to confirm the exact output configuration and gear ratio for your specific chassis before ordering.
