The Chelsea 871 Series Power Take-Off, part number 871XFQTP-B5XV or 871XFQTPB5XV, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. Continuous torque capacity reaches 670 lb-ft (908 N-m), and the series is rated for continuous-duty operation without derating. Nine speed ratios and thirteen output options cover a wide range of installation requirements. The compact housing reduces clearance concerns during installation, and multiple assembly arrangements maximize mounting flexibility. The 871 Series includes all three of Chelsea's premium options: Wet Spline pump flange, SmartStart for reduced shock load at start-up, and Quiet Gear input. A ductile iron bearing cap, 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap address vibration from modern engine designs. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
