The Chelsea 871 Series Power Take-Off, part number 871XGQTP-D5RY or 871XGQTPD5RY, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmission applications. The compact housing reduces clearance concerns during installation, while nine speed ratios and thirteen output options give you broad flexibility across fire and rescue, truck crane, pumper cleaner, and refuse applications. Continuous torque capacity reaches 670 lb-ft (908 N-m), with no derating required for continuous-duty operation. This unit carries three of Chelsea's specialized options: Wet Spline pump flange for extended PTO and pump shaft life, SmartStart to reduce shock load at start-up, and Quiet Gear input. A ductile iron bearing cap delivers 117% greater strength than gray iron, and an O-ring sealing configuration between housing and bearing cap improves clamp load while reducing vibration effects. Call us to confirm proper fit for your application.
