2. First of all, check that the sleeves are not skewed. For this purpose, a dial gauge is connected and installed on the contact surface of the cylinder block. Using a gauge, measure the top edge at five independent points and check whether the cylinder block surface is parallel. The maximum permissible deviation is 0.02 mm.
3. Check the amount of protrusion of each sleeve above the cylinder block using a ruler and a set of feeler gauges. Place a ruler on the surface of the cylinder liner so that it is perpendicular to the crankshaft, and measure the gap between the ruler and the surface of the cylinder block. If checking is performed after installing new cylinder liners, press on the cylinder liners to compress the gasket and only then insert the feeler gauge. Measure the gaps at the front and rear of the sleeve - they should not go beyond the established limits. Take measurements for all cylinders. After installing the new gaskets, you can tap the top edge of the sleeves to seat the gaskets, and then measure the protrusion again.
4. Check the difference in height between adjacent sleeves using a dial gauge. The height of the liners is measured along the central axis, parallel to the crankshaft. The difference in height between adjacent sleeves must not exceed the maximum permissible limits.
5. The three checks mentioned above (parallelism of the liner surface to the cylinder block, the amount of protrusion and the difference in height between adjacent liners) must be carried out sequentially, and the next check can only be carried out after making sure that the previous one has given the correct results. If, for example, you find that the cartridge case is tilted beyond the permissible limit, the cause of this must be identified and corrected (this may just be a device error, so you need to check it first). The reason for the skewing of the sleeve may be its deformation (it is most likely that the check is carried out on the engine while it is on the car) or foreign objects between the sleeve and the block (most likely if the check is carried out after a complete overhaul of the engine).
6. If the tests on the engine while it is in the car give unsatisfactory results, it will be necessary to replace the cylinder liners or even one or more cylinder liners. In any case, this will require removing the engine and gearbox.
7. If the tests are satisfactory, you can continue with the assembly or, if necessary, install temporary metal strips to hold the sleeves in place. Do not turn the crankshaft unless measures have been taken to prevent the cylinder liners from shifting. If you are not going to continue working immediately, cover the engine to prevent dirt from getting into it.
