The invention concerns a device for determining the internal measurements of a cylinder lining (6). Primarily large-size cylinder linings (6) are concerned, such as those used in marine engines. The device comprises a suspension unit (4) which is arranged to be placed above an essentially vertically upright cylinder lining (6). The device further comprises a measuring unit (5) which is arranged to be lowered from the suspension unit (4) into the cylinder lining (6) and which is provided with means (28, 34, 36) for performing a series of measuring operations and determining distances from a line of reference (11) extending between the suspension unit (4) and the measuring unit (5) to the inner wall (26) of the cylinder lining (6) at a plurality of levels and in several different radial directions at each level. |
