Can anyone tell me how to determine whether or not the crank is within specifications?

A friend of mine mentioned they used to measure the tolerance with the crank still in the engine casing. Can you do this with the NSR crank or does it need to be in V-Blocks?

Also I noticed one of the bearings (closest to the flywheel side) has the retaining pin broken off. The other two bearings are fine. Will the bearing spinning around in the crankcase be a problem?

Thanks
