The Chelsea 871XFQTP-D5RY or 871XFQTPD5RY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The series carries a continuous torque rating up to 670 lb-ft (908 N-m) with no derating required for continuous-duty operation. Nine speed ratios and thirteen output options cover a wide range of installation requirements. A ductile iron bearing cap delivers 117% greater strength compared to gray iron, while an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Wet Spline lubrication, SmartStart, and Quiet Gear options are all available on this series. The 871 Series succeeds the earlier 870 Series. Call us to confirm proper fit for your application.
