The Chelsea 871XGQTP-N5AC 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 torque up to 670 lb-ft (908 Nm) with no derating required for continuous duty use. A compact housing keeps overall height low to reduce clearance conflicts during installation, and multiple assembly arrangements give added mounting flexibility. The 871 Series features a ductile iron bearing cap rated 117% stronger than the gray iron cap used in its predecessor, the 870 Series, along with an o-ring sealing configuration between the housing and bearing cap to improve clamp load and resist the vibrational effects of modern engine designs. Part number 871XGQTP-N5AC or 871XGQTPN5AC is sold by Pro Gear and Transmission.
