Description
The Chelsea 281GDFJP-B3XV or 281GDFJPB3XV is a 281 Series Power Take-Off built for automatic transmissions with a 10-bolt aperture, including Allison transmissions. It uses hydraulic PowerShift engagement and supports continuous-duty operation. The 281 Series features a ductile iron bearing cap rated 117% stronger than gray iron, an O-ring sealing configuration between the housing and bearing cap to improve clamp load, and an enhanced clutch pack with 80% thicker steel discs to resist premature tooth wear. Rotatable cast-iron flanges reduce interference clearance issues. Nine speed ratios cover low and high-speed applications. Available with the Wet Spline Lubrication option for up to 7 to 10 times greater shaft life. SmartStart reduces shock load at start-up, and Electronic Overspeed Control (EOC) protects driven equipment. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
