The Chelsea 281GDFJP-B5XD or 281GDFJPB5XD is a Power Take-Off assembly built around a nine-ratio gear range covering both low and high speed selections. Bearing caps are ductile iron, rated 117% stronger than gray iron, and flanges are rotatable cast iron to reduce interference clearance issues. An O-ring sealing configuration controls vibrational effects and improves clamp load over standard seal designs. Driveline outputs include a positive-stop feature that prevents oil seal damage from coupling contact. The assembly supports a Wet Spline Lubrication option that extends shaft life 7 to 10 times compared to dry-spline configurations. SmartStart reduces shock load at start-up, and Electronic Overspeed Control (EOC) protects driven equipment from overspeed events. A hose is included in the assembly. Cross-references include 280GDFJP-B5XD and 3252PCE633SE. Call us to confirm proper fit for your application.
