The Chelsea 871 Series Power Take-Off, part number 871XDFJP-G5RY or 871XDFJPG5RY, is a 10-bolt PowerShift (hydraulic-shift) PTO designed for Allison transmissions. The 871 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 application requirements, from fire and rescue apparatus to refuse trucks, pumper cleaners, and truck cranes. A ductile iron bearing cap delivers 117% greater strength than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. The compact housing profile reduces clearance issues during installation. The 871 Series replaces the earlier Chelsea 870 Series PTO. Call us to confirm proper fit for your application.
