The Chelsea 871XAFJP-D5AB is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque rating of up to 670 lb-ft (908 Nm) with no derating required for continuous-duty operation. Its compact housing is engineered to reduce clearance issues during installation, and a ductile iron bearing cap delivers 117% greater strength than the gray iron cap used in the predecessor 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration. The 871 Series is the only Chelsea PTO to offer Wet Spline, SmartStart, and Quiet Gear options within a single platform. Available from Pro Gear and Transmission.
