The Chelsea 871LDFJW-B5TY is a Hot Shift (hydraulic PowerShift) Power Take-Off from the 871 Series, mounted on a 10-bolt pattern and 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 work, making it well suited for fire and rescue apparatus, refuse trucks, truck cranes, and pumper-cleaner equipment. The compact housing is engineered to reduce clearance conflicts during installation. A ductile iron bearing cap provides added durability over gray iron, and an o-ring sealing configuration between the housing and bearing cap improves clamp load. This part also cross-references to 870LDFJW-B5TY or 870LDFJWB5TY. Call us to confirm proper fit for your specific transmission and application.
