The Chelsea 871XFFJP-N5SB is a 10-bolt PowerShift (hydraulic) Power Take-Off from the 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. Its compact housing is built around a ductile iron bearing cap, which is 117% stronger than the gray iron used in the predecessor 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. The 871 Series supports nine speed ratios and thirteen output options, including SAE B, SAE BB, and SAE C pump spline configurations. Wet Spline, SmartStart, and Quiet Gear options are available within the series.
