The Chelsea 871 Series Power Take-Off assembly, part number 871LFFJW-B3TF or 871LFFJWB3TF, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options cover a wide range of application requirements, including fire and rescue, truck cranes, refuse, and pumper-cleaner trucks. 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 and improves clamp load. The 871 Series is the only Chelsea PTO to offer all three of Chelsea's premium options: Wet Spline, SmartStart, and Quiet Gear. Call us to confirm proper fit for your application.
