The Chelsea 871 Series Power Take-Off, part number 871XCQTP-D5RY or 871XCQTPD5RY, 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 need to derate for continuous-duty operation. Nine speed ratios and thirteen output options cover a wide range of application requirements, from fire and rescue apparatus to refuse trucks and pumper cleaners. 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 and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear features are available within this series. Call us to confirm proper fit for your application.
