**IE S004**  
Ukrzaliznytsia Locomotive Department · Ukraine · 2003–2005

Compressor current dropped, the air system filled up faster, treated gearbox teeth gained thickness. Ukraine · 2003–2005. 7-19 % — air system fill time.

## Measured

- current drawn by the compressor motor, 10.5-90 → 9.5-80 A — **5.5-12.8 %**
- air system fill time, 17.5-82 → 15-72 s — **7-19 %**
- diameter of worn compressor cylinders at teardown — **0.04-0.09 mm**
- tooth thickness of treated traction gearboxes — **0.25-0.55 mm**

## Conclusion

Compressor current dropped, the air system filled up faster, treated gearbox teeth gained thickness
