The exhaust side balance shaft must be replaced after removal.
Because of the small play between the balance shaft and cylinder block, the balance shaft may need to be cooled in order to install it. Check if the balance shaft can be inserted into the cylinder block without forcing it in. If this is not the case, then the balance shaft must be installed cooled.
