ACT OF EXPERIMENTAL LOCOMOTIVE TREATMENT, 2009
TEM2K locomotive: engine, compressor and wheel-motor blocks restored without teardown
with signatures and seals
Key results
| LOCOMOTIVE UNIT | SERVICE SINCE REPAIR | WHAT WAS MEASURED |
|---|---|---|
| 1-PDG4D FO engine No. 133 | 359 days | Oil clearance of main and connecting-rod bearing shells; oil pressure by controller notch |
| KT-6 compressor No. 20-04-311 | 359 days | Fill time from 7.0 to 8.0 atm; oil pressure |
| Wheel-motor blocks 1 and 6 | 359 days | Tooth thickness of pinions and bull gears at the pitch circle |
1-PDG4D engine: oil clearance in crankshaft bearings, mm
| BEARING No. | MAIN, BEFORE → AFTER | CONNECTING-ROD, BEFORE → AFTER |
|---|---|---|
| 1 | 0.15 → 0.15 | 0.16 → 0.16 |
| 2 | 0.16 → 0.16 | 0.17 → 0.15 |
| 3 | 0.18 → 0.16 | 0.19 → 0.17 |
| 4 | 0.17 → 0.15 | 0.15 → 0.15 |
| 5 | 0.15 → 0.13 | 0.14 → 0.10 |
| 6 | 0.15 → 0.15 | 0.15 → 0.09 |
| 7 | 0.15 → 0.15 | — |
According to the conclusion of the act, the clearance decreased by 3.6 % on the main bearing shells and by 15 % on the connecting-rod shells. At no measurement point did the clearance increase.
1-PDG4D engine: oil pressure by driver's controller notch
| CONTROLLER NOTCH | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| 0 | 2.5 | 2.8 |
| 1 | 2.5 | 2.7 |
| 2 | 2.5 | 2.7 |
| 3 | 3.2 | 3.3 |
| 4 | 3.8 | 3.9 |
| 5 | 4.5 | 4.6 |
| 6 | 4.6 | 4.6 |
| 7 | 4.7 | 4.8 |
| 8 | 4.8 | 5.0 |
Measured at an oil temperature of 60 °C. According to the conclusion of the act, the engine oil pressure rose by 3.8 %.
KT-6 compressor No. 20-04-311
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Fill time from 7.0 to 8.0 atm | 30 s | 28 s |
| Compressor oil pressure | 3.8 | 4.0 |
According to the conclusion of the act, the compressor output rose by 6.7 % and the oil pressure by 5.3 %.
Wheel-motor blocks: tooth thickness at the pitch circle, mm
| GEAR | WMB 1, BEFORE → AFTER | WMB 6, BEFORE → AFTER |
|---|---|---|
| Pinion (driving) | 18.4 → 18.5 | 18.3 → 18.3 |
| Bull gear (driven) | 17.8 → 18.1 | 17.8 → 18.0 |
According to the conclusion of the act, the tooth thickness of the wheel-motor block gears increased by up to 3.4 %; the table measurements show a gain of 0.1-0.3 mm.
Findings of the depot commission
The results refer to a TEM2K shunting locomotive with a 1-PDG4D engine, a KT-6 compressor and wheel-motor blocks of the stated service time; on other equipment and under different operating conditions the figures may differ. The original act with signatures and seals is published in full and available for download.
