Position the pistons and piston rings according to the cylinders they will operate in.

1. Install the top sealing ring into the first cylinder and use the bottom of the piston to push it into the cylinder to the base of the cylinder.

Warning! The upper and middle sealing rings are different, the outer surface of the middle ring is conical.

2. Using a feeler gauge, measure the gap in the ring lock.



3. Repeat the measurement process with the ring installed on top of the cylinder and compare the measurement results with the technical data.

4. If the gap is too small, it must be increased by grinding the ends of the ring.

5. If the ring gap is too large, check that the rings are properly matched to your engine.

6. Repeat the checking operation for each ring in the first cylinder and then for the rings in the remaining cylinders.

7. Install the piston rings on the pistons in the same manner as when removing them.

8. After installing the piston rings on the piston, check the ease of movement of the piston ring in the piston groove and install the piston ring locks.
