The Chelsea 871 Series Power Take-Off, part number 871LFFJW-B5TS or 871LFFJWB5TS, is a 10-bolt PowerShift (hydraulic) 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 applications. Nine speed ratios and thirteen output options cover a wide range of working equipment. A ductile iron bearing cap rated 117% stronger than gray iron, combined with an O-ring sealing configuration between the housing and bearing cap, address the vibrational effects of modern engine designs. The compact housing reduces clearance problems at installation. Optional Wet Spline pump flange, SmartStart shock-load reduction, Quiet Gear input, and Electronic Overspeed Control (EOC) make the 871 Series the only Chelsea PTO to offer all three of Chelsea's core protection solutions in one unit. Call us to confirm proper fit for your specific Allison transmission and application.
