The Chelsea 281 Series Power Take-Off Assembly, part number 281GPFJP-B5RK or 281GPFJPB5RK, is a hydraulically shifted (PowerShift) PTO designed for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar transmissions. The 281 Series is an evolution of the 280 Series, featuring 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 a Wet Spline Lubrication option extends shaft life by 7 to 10 times. Cross-references: 280GPFJP-B5RK or 280GPFJPB5RK, and 3252PME633SA. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
