The Chelsea 281 Series Power Take-Off Assembly, part number 281GMFJW-B5RZ or 281GMFJWB5RZ, is a hydraulically shifted hot-shift PTO designed for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar units. An evolution of the proven 280 Series, the 281 features 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 80% thicker steel discs in the clutch pack to resist premature tooth wear. Nine speed ratios cover both low and high ranges, and rotatable cast-iron flanges reduce interference with pump clearance. Applications span fire and rescue, truck cranes, pumper-cleaner, and refuse vehicles. Call us to confirm proper fit for your application.
