Cylinder liner overhaul

2021-07-05

The PC ring and cylinder liner are designed to always follow each other. Therefore, when a cylinder unit is overhauled, the PC ring must be inspected, cleaned and if intact, reused.

If the PC ring is removed from the liner for some reason, it is important to mark the correct position on the parts. The PC ring must be installed in the same position as when removed, because it is worn together with the cylinder liner.

Since the PC ring is worn to the same extent as the liner, it is not necessary to replace the PC ring during over-haul.
