The Chelsea 871 Series Power Take-Off, part number 871XCFJW-D3RS or 871XCFJWD3RS, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce damaging vibrational effects and improve clamp load. The compact housing minimizes clearance concerns during installation. Nine speed ratios and thirteen output options give you broad flexibility across applications including fire and rescue, refuse, truck cranes, and pumper-cleaner equipment. The 871 Series is the only Chelsea PTO to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. A genuine Chelsea part, sold by Pro Gear and Transmission.
