  Note!
t  For higher values, rectify the cylinders up to the allowance that they admit, according to the replacement piston oversize scale.
t  After rectifying, wash and dry the cylinders and eliminate the particles on the walls with thick oil.
t  The calibrating operation must not be carried out with the block fixed on the rotating stand, as incorrect measurements could result from the stresses.
