Piston Ring Replacement Method?
1 Answers
Here are the steps for replacing piston rings: 1. For the twist ring, the inner circular groove should face upward, while the outer circular groove ring's groove should face downward. 2. The small end of the taper-faced ring should face upward. 3. For rings with inner circular chamfers, the chamfer should face upward. 4. For rings with outer circular chamfers, the chamfer should face downward. 5. Some piston rings are marked with "TOP" or "0", "△" symbols on one side. During installation, the marked side must face upward. 6. Barrel-faced rings or chrome-plated rings should be installed in the first groove. 7. When installing a composite steel oil ring, first insert the expander into the groove, then install the upper and lower scraper rails, ensuring their openings are staggered by 180°.
