The Chelsea 281GGFJP-H5XD is a PowerShift (hydraulic) hot-shift Power Take-Off assembly from the Chelsea 281 Series, designed for automatic transmissions with a 10-bolt aperture, including Allison applications. The 281 Series is an evolution of the widely used 280 Series and incorporates a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap for improved clamp load, and steel clutch disc thickness increased by 80% over the predecessor. Nine speed ratios are available across the series, and the design supports continuous operation. Common markets include fire and rescue, refuse, truck cranes, and pumper-cleaner trucks.
