The program for repairing traction rolling stock in the repair locomotive depot Far Eastern suggests the following types of maintenance and current repairs: maintenance TI_2, TO_3; Current repair TP_1, TR_2, TR_3; Middle Repair of Wed.

In the repair system, much attention is paid to the maintenance of locomotives. Maintenance is a complex of operations to maintain the performance and serviceability of the locomotive.

Maintenance is different from the repair and maintenance of work. Most of the work is performed on the TPS without removing the equipment and the use of machine processing. Main restoration work at: adjustment, plumbing in place, replacement of unsuitable or fast wear parts when they achieve limit tolerances for new, lift, fastening, adding or changing lubricants in friction nodes.

Conducting should provide a high coefficient of technical readiness of locomotives, their uninterrupted and trouble-free operation in accordance with the train schedule, long-term efficiency. Special control is subject to running parts, brake equipment, devices of locomotive alarm, speedymen, vigilance and radio control devices, i.e., all nodes and aggregates, the serviceable state of which ensures the safety of trains.

Maintenance TI_2 and TO_3 is periodic and intended to monitor the technical condition of nodes and locomotive systems in order to prevent failure to operate.

Maintenance TI_2 is performed by a comprehensive brigade at the locomotive maintenance clause (PTOL), which is a specialized separation of the repair locomotive depot. Ptol is equipped with appropriate equipment and the necessary margin of parts and materials. Performed by highly qualified repair workers. In the process, it is checked: the sequence of operation of electrical apparatus, the state of batteries, the operation of diesel-aggregates and the rotational speed regulators, the status of the bucks of wheel steam, spring suspension and lever braking system, and are blurred with compressed electrical machines.

Maintenance TI_3 is performed by a complex brigade of the T-3 workshop and employees - specialists from other depot workshops. This type of maintenance occupies a special place among other types of maintenance. In terms of repair work and time spent locomotives, this type of maintenance more refers to repairs. At T-3 perform the works provided for by TO-2, and additionally: inspect and check the frequency of rotation of the crankshaft of the diesel engine and the timing of the limit regulator; tested tightness and purged by air section of refrigerators; remove and experience at the booth of the nozzle; inspect the pistons and purify the windows of the cylinder sleeves from the car; Filters are washed or replaced by new; inspect and blow electric machines with air; measure the resistance of power and auxiliary chains; Check the mounting of motor-axial bearings and engine suspensions; Check the condition and characteristics of current collectors; inspect the fuses and contactors of high-voltage chains and control circuits; inspect the wheeled pairs, letters, spring suspension; produce fastening of the crew parts; Check the level and density of electrolyte battery batteries, sandbox nozzles and sand and dr.

Repair - a range of operations to restore health, performance and a resource of a locomotive, a regulatory appearance that meets the requirements of the PTE, as well as eliminating failures and faults arising from the operation of the TPS on the line or detected during the maintenance process. Repair system is designed to eliminate malfunctions and restoring performance, ensuring reliability and operational reliability by disassembling, restoring the size and properties or replacement of unsuitable parts, catch and locomotive units.

The volume of mandatory work performed with all types of maintenance and repair of the TPS of each type and type (series) are governed by the rules of the current and overhaul of the electrical composition, diesel locomotives, diesel trains, instructions for the maintenance of electric trains in operation.
