The ball bearings in the recirculating circuit are two different sizes. The differ in size by 0.0005 inch. That difference is too small to get an accurate direct measurement with a micrometer. However, you can seperate them by feel! Set the mike and slide them through. Some will be "tight" others will be "loose". Place them in seperate piles and alternate them into the circuit.
Originally they were different colors. They must be placed in the circuit alternating sizes as mentioned above. A competent rebuilder should know this.
