The Chelsea 871XDFJP-B3RF or 871XDFJPB3RF is a 10-bolt PowerShift (hydraulic) Power Take-Off from Chelsea's 871 Series, designed for Allison transmission applications. This series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 N-m) and nine available speed ratios covering both low and high speed ranges. Thirteen output configurations are offered, including SAE B, SAE BB, and SAE C pump splines and multiple flange options. The compact housing keeps installation height low, reducing clearance conflicts on tight-fit truck chassis.
