CHECK VALUES FOR PISTON RINGS
| Number | Designation | Engine 156 | ||
|---|---|---|---|---|
| BE03.10-P-1002-05D | Piston ring end gap | Groove 1 | mm | 0.2 to 0.35 |
| Groove 2 | mm | 0.35...0.55 | ||

- Clean cylinder wall.
- Insert both compression rings, one after the other, above running surface in the cylinder bore, and measure end gap with a
feeler gauge; replace piston rings if necessary.
The end gap of the oil scraper ring cannot be measured because of its three-part design. The oil scraper ring must also be replaced when the compression rings are replaced.
