The Chelsea 281GGFJP-B5SD or 281GGFJPB5SD is a Power Take-Off assembly built around a 10-bolt, P-shift mounting configuration. It delivers nine speed ratios spanning low and high ranges, giving fleet and vocational applications broad output flexibility. The bearing cap is ductile iron, rated 117% stronger than gray iron, and paired with an O-ring sealing configuration that resists vibrational loosening and maintains clamp load. Rotatable cast-iron flanges reduce interference-fit clearance problems on installation. A Positive Stop driveline output prevents oil seal damage from coupling contact. The SmartStart feature reduces shock load at engagement, and Electronic Overspeed Control (EOC) protects driven equipment from runaway speed events. Call us to confirm proper fit for your transmission and application.
