Abstract: A variable vane assembly for use in a gas turbine engine includes a variable vane, an actuator, and a mechanical linkage. The mechanical linkage connects the variable vane to the actuator. The mechanical linkage includes a bellcrank rotatable about an axis, a first bellcrank arm having a first clevis at an inner end, and a first pin extending through the first clevis and a first flange of the bellcrank to fasten the first bellcrank arm to the bellcrank.
