I checked the documentation. Standard size is 70.062mm, which currently it is. Regrind should be 69.762mm, 0,3mm under. So we will take 0,25mm main bearings but they will do it with the crankshaft and the block to the exact measurements of the oversize bearings.
There is big marking "R" still visible on one of the counterweights.
Will replace the bearing with the SKF, too (made in China currently installed).
