Values of axial mounting clearances of piston rings
| Piston ring, dimension in mm | Gap for new ring | Clearance at wear limit |
| 1st compression ring | 0.04-0.08 mm | 0.15 mm |
| 2nd compression ring | 0.04-0.08 mm | 0.15mm |
| Oil scraper ring | Impossible to measure | |
Checking clearance between piston ring and groove in axial direction
Before checking, the groove in the piston should be cleaned.
