The Chelsea 281GCFJP-D5AC or 281GCFJPD5AC is a hydraulically shifted hot-shift Power Take-Off from Chelsea's 281 Series, designed for automatic transmissions with a 10-bolt aperture, commonly Allison applications. This PTO carries a single, continuous duty torque rating and offers nine speed ratios covering low and high ranges. A ductile iron bearing cap delivers 117% greater strength than gray iron, while an o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational effects. The clutch pack features 80% thicker steel discs to resist premature tooth wear. Rotatable cast-iron flanges reduce interference issues, and the Positive Stop feature protects driveline output oil seals from coupling damage. The Wet Spline Lubrication option extends shaft life 7 to 10 times. SmartStart reduces shock load at start-up, and the Electronic Overspeed Control (EOC) safeguards driven equipment. Common markets include fire and rescue, refuse, pumper-cleaner, and truck cranes. Call us to confirm proper fit for your application.
