The Chelsea 871LGFJW-B3TK is a 10-bolt PowerShift (hydraulic shift) 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 operation. Its compact housing is engineered to reduce clearance conflicts during installation, and multiple assembly arrangements give installers flexibility in tight chassis environments. The 871 Series features a ductile iron bearing cap, reported to be 117% stronger than the gray iron cap used in the predecessor 870 Series, along with an o-ring sealing configuration between the housing and bearing cap to improve clamp load and reduce vibration-related wear. Nine speed ratios and thirteen output options are available across the series. Part number 871LGFJW-B3TK or 871LGFJWB3TK is sold by Pro Gear and Transmission.
