Description
The Chelsea 871XAFJP-H3AC or 871XAFJPH3AC is a 10-bolt PowerShift (hydraulic shift) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series delivers continuous-duty torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. A ductile iron bearing cap rated 117% stronger than gray iron and an O-ring sealing configuration between the housing and bearing cap reduce vibrational stress and improve clamp load. Nine gear ratios and thirteen output options give installers a wide range of speed and mounting configurations. Available options include Wet Spline pump flange for extended shaft life, Quiet Gear input, SmartStart for reduced shock load at start-up, and Electronic Overspeed Control (EOC) for driven equipment protection.
