The Chelsea 871XEFJP-G5XV or 871XEFJPG5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off Assembly from the 871 Series, 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 operation. Nine speed ratios and thirteen output options give this unit broad application coverage across fire and rescue, truck cranes, pumper/cleaner, and refuse vehicles. 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 the vibrational effects of modern engine designs. Wet Spline, SmartStart, and Quiet Gear options are available. Cross-references include 870XEFJP-G5XV and 870XEFJPG5XV. Call us to confirm proper fit for your application.
