The Chelsea 281GSFJW-B3RK or 281GSFJWB3RK is a 281 Series hydraulically shifted (PowerShift) power take-off built for automatic transmissions with a 10-bolt aperture, including Allison and Caterpillar applications. The series carries a 390 lb-ft continuous torque rating and delivers nine speed ratios spanning low and high ranges. Key structural upgrades over the earlier 280 Series include a ductile iron bearing cap rated 117% stronger than gray iron and an 80% thicker clutch pack to resist premature tooth wear. An O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Common markets include fire and rescue, truck cranes, pumper/cleaner, and refuse. Call us to confirm proper fit for your specific transmission and application.
