You can use "plastigauge", sold at automotive supply houses to measure clearance. Thumbrule is 0.001 inches of clearance per inch of journal diameter.

Thanks Fred, what should I use for spacer? To open up the bearing halves.

You can get laminated brass shim stock from McMaster Carr. This allows for future bearing adjustments by peeling off a layer as needed.
