The Chelsea 871XBFJP-N5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series delivers continuous torque capacity up to 670 lb-ft (908 Nm) with no derating required for continuous duty operation. Its compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger than the gray iron predecessor. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibrational stress from modern engine designs. The 871 Series offers nine speed ratios and thirteen output options, and is the only Chelsea PTO line to combine Wet Spline, SmartStart, and Quiet Gear options in a single platform. Common markets include fire and rescue, refuse, pumper cleaner, and truck crane applications. Available from Pro Gear and Transmission.
