The Chelsea 871XJFJP-N5AC is a 10-bolt PowerShift (hydraulic shift) 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 is engineered to reduce clearance conflicts during installation, and multiple assembly arrangements provide flexibility across a range of mounting configurations. The ductile iron bearing cap is 117% stronger than the gray iron cap used in the predecessor 870 Series, and an o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related stress. Output shaft options across the 871 Series include SAE B, SAE BB, and SAE C pump spline configurations as well as flange outputs. The 871 Series is available with Wet Spline, SmartStart, and Quiet Gear options. Sold by Pro Gear and Transmission.
