The bearing in the clutch bell is a 6x10x5.

Blade grips are 8x16x5, 2 in each grip and a thrust bearing in each grip.

The bearing that the pinion inserts into, the one in the bottom of the bearing block is a 10x19x5.

I know pretty much all the dimensions by heart and I will get back later with the rest of the dimensions.

MA uses bearings that have metric dimensions. Yes any bearing the size can be posted in inches or millimeters. MA has always used metric measurements for the bearings they use. The bolts are also metric, as is most of the parts on the heli.
Just found it amusing someone would drag out a thread old as this one.
