The Chelsea 281 Series Power Take-Off, part number 281GCKVP-B8RK or 281GCKVPB8RK, is a hydraulically shifted hot-shift PTO built for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar applications. Evolved from the popular 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 for improved clamp load, and an enhanced clutch pack with 80% thicker steel discs to resist premature tooth wear. Nine speed ratios cover both low and high-speed requirements. Rotatable cast-iron flanges reduce interference issues with pump mounting. A genuine Chelsea part sold by Pro Gear and Transmission.
