ChME3 ball supports: clearance to gauge smaller, on the control one — larger
The gauge clearance on treated supports decreased, on the control one it grew over the same mileage. 0.04–0.07 mm — clearance to gauge on the treated supports, single maximum 0.65 mm; 0.08–0.1 mm — clearance on the control support without XADO, 0.3–0.32 → 0.38–0.42 mm (2003).

Clearance to the R110 gauge — before treatment and after mileage
| LOCOMOTIVE | BODY SUPPORT | BEFORE TREATMENT, mm | AFTER MILEAGE, mm |
|---|---|---|---|
| ChME3 No. 1736 | Front left (post No. 1) | 0.9-0.1 | 0.83-0.06 |
| ChME3 No. 1736 | Rear left (post No. 4) | 0.22–0.25 | 0.16–0.20 |
| ChME3 No. 3825 | Front left | 0.2–0.22 | 0.14–0.18 |
| ChME3 No. 3825 | Rear left | 0.1–0.12 | 0.06–0.07 |
| ChME3 No. 7218 | Front left | 1.45–1.5 | 0.8–0.85 |
| ChME3 No. 7218 | Rear left — control, without XADO grease | 0.3–0.32 | 0.38–0.42 |
Clearance between the R110 ± 0.1 mm gauge and the working surface of the spherical washer; the range is the spread across measuring points. The control support ran the same mileage on the same machine.
Conclusion of the depot commission
