The Chelsea 871XAFJP-N5RK is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. 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 conflicts at installation, and a ductile iron bearing cap delivers 117% greater strength than the gray iron predecessor used in the 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the effects of drivetrain vibration. Output options span thirteen configurations, including SAE B, SAE BB, and SAE C pump splines, companion flanges, and DIN flange types. Available with Wet Spline, SmartStart, and Quiet Gear options.
