871XGFJW-B3RY Chelsea PTO Assembly

The Chelsea 871 Series Power Take-Off (part number 871XGFJW-B3RY or 871XGFJWB3RY) is a 10-bolt, hydraulic PowerShift 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 give this unit flexibility across fire and rescue, refuse, truck crane, and pumper cleaner applications. 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. Options include Wet Spline pump flange, SmartStart for reduced start-up shock load, Quiet Gear input, and Electronic Overspeed Control (EOC). The compact housing minimizes clearance concerns during installation. Call us to confirm proper fit for your specific application.
