Your pinblock is likely over 100 years old. It is cracked. IMHO, it is very risky to simply repin with one or two size bigger pins. I strongly suggest restoring the pinblock with plugs (if the block appears to be in pretty good structural condition after close inspection with the plate out), or replacing the pinblock. I see so many "rebuilt" old pianos where bigger pins were installed and so often several or many pins will not hold a tuning or are near that point and torque across the block is all over the place. New holes in a strong block with original sized pins is the way to go. The Bechsteins with an open faced pinblock have those nice 1/0 pins. Sure would be nice to retain use of that size. Stepping up one pin size and doing nothing to the block (maybe reaming holes to remove any glazing) is for blocks (generally speaking - any given block may vary) that are anywhere from nearly new to less than 50 years old (basically on a piano that has a pinblock that looks real, real good and has a history of nice even torque).
