The Chelsea 871 Series Power Take-Off, part number 871XGFJP-B3RY or 871XGFJPB3RY, is a 10-bolt PowerShift (hydraulic shift) PTO designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications, making it a fit for fire and rescue, refuse, truck crane, and pumper-cleaner equipment. Nine speed ratios and thirteen output options cover a wide range of drive configurations. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibration-induced clamp-load loss. Wet Spline lubrication, SmartStart, and Quiet Gear are all available on this series. Call us to confirm the right fit for your application.
