Description
The Chelsea 871 Series Power Take-Off, part number 871XEFJW-B5RY or 871XEFJWB5RY, is a 10-bolt PowerShift (hydraulic) PTO engineered for Allison transmissions. The 871 Series is rated for continuous-duty operation at torque capacity up to 670 lb-ft (908 N-m), with shaft power reaching 128 HP at 1,000 RPM. Nine speed ratios and thirteen output options give installation flexibility across a wide range of truck applications, including fire and rescue, refuse, truck cranes, and pumper-cleaner equipment. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects while improving clamp load. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear as available options on a single platform. Call us to confirm proper fit for your application.
