The Chelsea 871XGFJP-B3SV is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmissions. The 871 Series features a compact housing to minimize clearance issues and a ductile iron bearing cap rated 117% stronger than gray iron. An o-ring sealing configuration between the housing and bearing cap improves clamp load and reduces vibration-related wear. The series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 N-m) and shaft output of 128 HP at 1,000 RPM. Nine speed ratios and thirteen output options give installers broad flexibility across fire and rescue, refuse, truck crane, and pumper cleaner applications.
