When repairing a cylinder block, it is necessary to bore and hone the cylinders to fit the increased diameters of pistons of repair sizes (by 0.4 and 0.8 mm) and taking into account the provision of a gap of 0.025-0.045 mm, which is measured in the same way as on the 2121 engine. To set the bore gauge to zero, the 67.8125.9502 gauge is used.
