The Chelsea 871XJQTP-N5AC is a 10-bolt, hydraulic PowerShift Power Take-Off from the 871 Series, designed for Allison transmissions. The 871 Series carries a continuous torque capacity of up to 670 lb-ft (908 Nm) with no derating required for continuous duty operation. A compact housing keeps clearance issues to a minimum, and the ductile iron bearing cap is 117% stronger 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 reduces the effects of engine vibration. The 871 Series supports Wet Spline, SmartStart, and Quiet Gear options, and offers nine speed ratios across thirteen output configurations. Shaft power output is rated at 64 HP at 500 RPM and 128 HP at 1,000 RPM.
