The Chelsea 281GMFJW-B5RK or 281GMFJWB5RK is a Power Take-Off assembly built around nine speed ratios covering both low and high speed ranges. Ductile iron bearing caps deliver 117% greater strength compared to gray iron, while an O-ring sealing configuration reduces vibrational effects and improves clamp load over conventional seal designs. Rotatable cast-iron flanges address interference clearance issues, and driveline outputs include a positive stop to prevent oil seal damage from coupling contact. The optional wet spline lubrication provision extends shaft life by 7 to 10 times. SmartStart technology reduces shock load at start-up, and Electronic Overspeed Control (EOC) protects downstream driven equipment. Call us to confirm proper fit for your transmission and application.
