I. Compression rings
II. Lateral elements of the oil scraper ring
Installation
1. Before installation, it is necessary to check the end and side clearances of the piston rings.
2. Install the upper compression ring into the cylinder using the piston.
3. Measure the ring end clearance with a feeler gauge. If the clearance is too small, replace the piston rings or file the ends of the existing rings with a fine file. Be careful, piston rings are sharp and break easily.
