The Chelsea 871 Series Power Take-Off, part number 871XEFJP-L3XV or 871XEFJPL3XV, is a 10-bolt PowerShift (hydraulic-shift) PTO engineered for Allison transmissions. 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 configurations give installers broad flexibility across fire and rescue, refuse, pumper cleaner, and truck crane applications. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Optional Wet Spline pump flange, SmartStart, and Quiet Gear features are available within the 871 Series. Call us to confirm the exact configuration for your application.
