281GPFJP-D5XV Chelsea PTO Assembly

The Chelsea 281GPFJP-D5XV or 281GPFJPD5XV is a hydraulically shifted hot-shift Power Take-Off in Chelsea's 281 Series, designed for automatic transmissions with a 10-bolt aperture - most commonly Allison and Caterpillar transmissions. The 281 Series mounts with a 10-bolt pattern and carries a continuous torque rating of 390 lb-ft (529 Nm). Shift type is PowerShift (hydraulic). Output options in this series include SAE B and SAE C pump flanges, ISO 7652 flange, and driveline configurations. The ductile iron bearing cap is 117% stronger than the gray iron cap used in predecessor designs, and the clutch pack features steel discs that are 80% thicker for reduced tooth wear. An o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibrational effects. Call us to confirm proper fit for your application.
