The Chelsea 871 Series Power Take-Off Assembly, part number 871XFFJP-D3AC or 871XFFJPD3AC, is a 10-bolt PowerShift (hydraulic) PTO designed for Allison transmissions. The series carries a continuous torque rating of 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 improves clamp load while reducing vibrational effects from modern engine designs. Optional Wet Spline, SmartStart, and Quiet Gear features are available within the 871 Series. Call us to confirm the correct configuration for your application.
