The Chelsea 281GGFJP-B3RK or 281GGFJPB3RK is a Series 281 Power Take-Off Assembly built for continuous-duty commercial truck applications. Nine speed ratios cover both low and high speed demands, while a ductile iron bearing cap construction delivers 117% greater strength than gray iron. The O-ring seal configuration reduces vibration effects and improves clamp load retention. Rotatable cast-iron flanges cut interference clearance issues, and the positive-stop driveline output protects oil seals from coupling damage. The optional Wet Spline Lubrication circuit extends shaft service life 7 to 10 times over a dry spline. Electronic Overspeed Control (EOC) safeguards driven equipment, and SmartStart reduces shock load at engagement. Hose is included. Call us to confirm proper fit for your application.
