The Chelsea 871XAFJP-E5XV is a 10-bolt PowerShift (hydraulic shift) Power Take-Off Assembly 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 is engineered to reduce clearance issues, and the ductile iron bearing cap is 117% stronger than the gray iron cap used in its predecessor, the 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and helps reduce the effects of engine vibration. Common markets for this series include fire and rescue, refuse, pumper cleaner, and truck crane applications. Pro Gear and Transmission carries this as a genuine Chelsea part.
