Check that the walls of the cylinder bore are perfectly smooth. Measure the cylinder bore diameter (D) at three different
heights and in two directions offset by 90°, thereby determining the assembly clearance, taper, and ovality (see specified
values in Section 3 - 1.1,
Cylinder/Piston).
In the event of damage or excessive wear the barrel must be renewed as it has a silicon carbide coating (which provides
the cylinder walls with excellent anti-friction and anti-wear properties) and therefore cannot be rebored.
The cylinders are marked by a letter (punched into the specific surface on the cylinder side) showing the size class to
which they belong.
Always match cylinders with pistons from the same size class.
