The Chelsea 871 Series Power Take-Off assembly, part number 871XFFJP-G5RF or 871XFFJPG5RF, is a 10-bolt hydraulic PowerShift PTO designed for Allison transmissions. The series delivers continuous torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous-duty applications. Nine speed ratios and thirteen output options cover a wide range of installation requirements, while the compact housing height keeps clearance issues to a minimum. A ductile iron bearing cap, 117% stronger than gray iron, pairs with an O-ring sealing configuration between the housing and bearing cap to resist vibration-induced clamp-load loss. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options in a single platform, serving fire and rescue, refuse, truck crane, and pumper-cleaner applications. Call us to confirm proper fit for your specific transmission and application.
