AR03.10-P-7311-01MCC Measure Vertical Clearance Of Piston Rings












Shown on plain compression ring which has been removed
1. Measure the side clearance of the plain compression ring (1) in groove 1 and the taper-faced ring (2) in groove 2 using a suitable feeler gauge (4).
There should be no combustion residues in the piston ring groove during measurement.
The side clearance of the oil scraper ring in groove 3 cannot be checked due to its three-part structure.
The plain compression ring (1), taper-faced ring (2), oil scraper ring must be replaced together with the piston (3) if wear is found.
