The Chelsea 871XBQTP-D5RY or 871XBQTPD5RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 871 Series, designed for Allison transmission applications. Torque capacity reaches up to 670 lb-ft (908 N-m), and the series is rated for continuous duty without derating. The compact housing reduces clearance issues during installation, while a ductile iron bearing cap delivers 117% greater strength than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. Nine speed ratios and thirteen output configurations give technicians broad flexibility to match pump and application requirements. Chelsea's 871 Series also supports Wet Spline, SmartStart, and Quiet Gear options. Call us to confirm the right configuration for your application.
