The Chelsea 281GDFJP-B5RF or 281GDFJPB5RF is a Power Take-Off assembly built for continuous duty applications. Nine speed ratios cover both low and high speed ranges, giving fleet operators and upfitters broad flexibility across hydraulic-driven equipment. Ductile iron bearing caps deliver 117% greater strength than standard gray iron caps. An O-ring sealing configuration reduces the effect of vibration and improves clamp load retention. Rotatable cast-iron flanges reduce interference fit issues at installation. The Positive Stop feature on driveline outputs eliminates oil seal damage from coupling contact. Wet spline lubrication is available as an option, extending shaft life by 7 to 10 times. SmartStart technology softens shock load at engagement, and Electronic Overspeed Control (EOC) protects driven equipment from overspeed events. Sold by Pro Gear and Transmission.
