The Chelsea 281 Series Power Take-Off, part number 281GGFJW-B5RF or 281GGFJWB5RF, is a hydraulically shifted hot-shift PTO designed for automatic transmissions with a 10-bolt aperture, including Allison transmissions. The 281 Series is an evolution of the top-selling 280 Series, featuring a ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between housing and bearing cap for improved clamp load, and an enhanced clutch pack with steel discs 80% thicker than the previous design. Nine speed ratios cover both low and high-speed requirements. Rotatable cast-iron flanges reduce interference issues at the pump mounting face. Available output types include SAE B and SAE C pump flanges, ISO 7652 pump flange, and driveline outputs. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
