Repair of the Two-Machine Unit MVT25/9+MVG25/11

The MVT25/9+MVG25/11 unit is a complex piece of equipment used to ensure the reliable operation of the TEM2 diesel locomotive and requires regular maintenance and repair to maintain its functionality and longevity.

The repair of the MVT25/9+MVG25/11 two-machine unit installed on the TEM2 locomotive involves several key stages.

First, a complete diagnosis of the unit is performed to identify any malfunctions and defects. This may include checking the cooling system, the condition of the piston rings, main and connecting rod bearings, as well as analyzing the operation of the fuel and exhaust systems.

After diagnosis, the unit is disassembled into its components. It is important to carefully label and package all parts to avoid confusion during reassembly.

Next, all key components of the unit, such as cylinders, pistons, shafts, and bearings, are checked. Worn or damaged parts are replaced with new or repaired ones.

After checking and replacing the necessary parts, the unit is reassembled in the reverse order. All connections must be properly tightened, and all assemblies checked for compliance with technical requirements.

Following assembly, the unit undergoes testing. Its functions and performance are checked under conditions close to real operational scenarios.

After successful testing, the unit is installed on the TEM2 locomotive. Its integration with the locomotive’s systems is carried out, and its correct operation is verified.
