Measuring a cylinder
Prerequisite
Cylinder path is cleaned.
Check
- Adjusting measuring screw to nominal dimension of cylinder bore.

- Insert internal measuring device into micrometer and set to zero.
- With the internal measuring device, measure the cylinder at the following points and check the deviations from the nominal dimension.
- Lower third of the cylinder bore in direction of travel,
- Lower third of the cylinder bore transversely to direction of travel,
- Middle third of the cylinder bore in direction of travel,
- Middle third of the cylinder bore transversely to direction of travel,
- Upper third of the cylinder bore in direction of travel,
- Upper third of the cylinder bore transversely to direction of travel.
