Checking cylinder diameters
Accurately measure cylinder diameters. Measurements to be made with a caliper in three belts as in the transverse direction «A», and in the longitudinal direction «IN», as shown in the diagram.
In cases where wear exceeds the allowable value by more than 0.04 mm, repair the cylinders to the nearest repair size and install pistons of the corresponding repair size.
Cylinder blocks are marked at the factory depending on the diameter of the cylinders and pistons. The corresponding label is located next to the generator mounting location.
