Check end clearance of piston rings
Prerequisite
Cylinder path is cleaned.
Cylinder was measured and is within the permissible tolerances.
NOTE:
Schematic diagram is for example purposes. Some parts may differ in certain details.
Check
- Connect the upper piston ring to the cylinder and push it with the piston to the upper dead center.
- Check the end clearance of the upper piston ring with a feeler gauge.
TECHNICAL DATA - CLEARANCE OF UPPER PISTON RING SPECIFICATION
| End clearance of upper piston ring | ||
|---|---|---|
| Before measuring the end clearance, make sure the cylinder is within the permissible tolerance. | 0.20 mm... 0.28 mm | |
Result
» End clearance is outside tolerance.
Measure
- Replace upper piston ring.
Check
- Take upper piston ring out of the cylinder.
- Connect the central piston ring to the cylinder and push it with the piston to the upper dead center.
- Check the end clearance of the center piston ring with a feeler gauge.
TECHNICAL DATA - CLEARANCE OF CENTER PISTON RING SPECIFICATION
| End clearance of center piston ring | ||
|---|---|---|
| Before measuring the end clearance, make sure the cylinder is within the permissible tolerance. | 0.20 mm... 0.28 mm | |
Result
» End clearance is outside tolerance.
Measure
- Replace center piston ring.
