Overhauling the cylinder/piston components

Overhauling the cylinder

Check that the walls of the cylinder are perfectly smooth. Measure the cylinder diameter at three different
heights and in two directions at 90° between them to obtain the coupling, tape and ovality value.
In the event of damage or excessive wear the cylinder must be replaced as it has a silicon carbide coating
(which provides the cylinder walls with excellent anti-friction and anti-wear properties) and therefore
cannot be ground.
The cylinders are marked with a letter (stamped in a specific area on the cylinder side) indicating their size
class.
Always match cylinders with pistons from the same size class.
