The Chelsea 871 Series Power Take-Off, part number 871XJFJP-D5RY or 871XJFJPD5RY, is a compact 10-bolt hydraulic PowerShift PTO engineered for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 N-m) with no derating required for continuous-duty use. Nine available speed ratios and thirteen output options give spec teams broad flexibility across fire and rescue, truck crane, pumper/cleaner, and refuse applications. The ductile iron bearing cap is 117% stronger than gray iron, and the o-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. Wet Spline, SmartStart, and Quiet Gear options are all available on this series. Call us to confirm the correct assembly arrangement for your installation.
