The Chelsea 871LAFJW-G5TY is a 10-bolt PowerShift (hydraulic) Power Take-Off from the Chelsea 871 Series, designed for Allison transmission applications. The 871 Series features a compact housing that reduces clearance concerns and a ductile iron bearing cap rated 117% stronger than the gray iron cap used in the predecessor 870 Series. An o-ring sealing configuration between the housing and bearing cap improves clamp load and resists vibration from modern engine designs. The series supports continuous-duty operation with torque capacity up to 670 lb-ft (908 Nm) and shaft power of 64 HP at 500 RPM or 128 HP at 1,000 RPM. Nine speed ratios and thirteen output options cover a wide range of working configurations. Available from Pro Gear and Transmission.
