The Chelsea 281GKFJP-D3RZ or 281GKFJPD3RZ is a 281 Series hydraulically shifted PowerShift power take-off designed for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar transmissions. An evolution of the Chelsea 280 Series, the 281 Series adds 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 an 80% thicker steel clutch pack to resist premature tooth wear. Nine speed ratios cover both low and high ranges, and the wet spline lubrication option delivers 7 to 10 times greater shaft life. A genuine Chelsea part from Pro Gear and Transmission.
