Lock cylinder (Fig. 3.5) cast iron integrally with the cylinder. According to the diameter of the cylinders are divided into five size groups, these figures on the upper end surface of the block in front of each cylinder from the fuel pump. The dimensional characteristics of the cylinder are presented in Table. 3.1. Checking the technical condition and repair cylinder diesel engine is similar to the instructions of the relevant Sect. "Gasoline Engines."
