2. Lay out the pistons assembled with connecting rods and new piston rings in such an order that the set of rings corresponds to the cylinder in which the clearance will be measured and in which the checked rings will be installed.
3. Insert the upper ring into the first cylinder and push the piston head inward by 15-20 mm so that the ring inside the cylinder becomes perpendicular to its axis. Take out the piston.
4. Measure the gap with a feeler gauge and compare the result with the standard (see photo).
5. If the gap is too small, then carefully file the ends of the ring with a thin file.
6. If the clearance is higher than normal, then make sure that the ring corresponds to this engine and cylinder size group.
7. Repeat the procedure for each ring of the first cylinder, as well as for the rings of the remaining cylinders. Keep rings and pistons corresponding to the same cylinder together.
8. Install the oil scraper ring on the piston. Install the expander into the groove. Then, between the expander and the piston groove pads, install in order the upper and lower disks of the oil scraper ring (see photo).
9. Install the lower compression ring (see photo). Install the top compression ring with the correct orientation.
Attention! When installing rings, follow the instructions that come with the ring kit, as different manufacturers recommend different procedures for installing rings on the piston. Do not mix up the top and bottom compression rings. On some of the engines under consideration, there is no orientation mark on the upper compression ring.
10. Arrange the joints of the rings in accordance with the photo.
