The Chelsea 871XBQTP-B5XV is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 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 applications. Its compact housing is engineered to reduce clearance conflicts during installation, and multiple assembly arrangements expand mounting options. The 871 Series succeeds the popular 870 Series, featuring a ductile iron bearing cap rated 117% stronger than the gray iron predecessor, plus an o-ring sealing configuration between the housing and bearing cap for improved clamp load and resistance to engine-induced vibration. Nine speed ratios and thirteen output options give this unit broad application coverage across fire and rescue, refuse, truck crane, and pumper cleaner vocations.
