3.16.23. Installation of piston rings
THE GENERAL DATA

Arrangement of piston rings on the piston


Arrangement of label R or N on a piston ring

Label R or N on a piston ring should be directed to piston top.

Arrangement of locks of piston rings on the piston


PERFORMANCE ORDER
1. Before installation of new piston rings check up a backlash in the lock of a piston ring.
2. Arrange pistons and piston rings according to cylinders in which they will work.
3. Establish a piston ring in a piston flute.
4. By an edge щупа measure a backlash of a piston ring in a piston flute.
5. Establish the top sealing ring in the first cylinder and the piston bottom push it in the cylinder to the cylinder basis.
6. Using щуп, measure a backlash in the lock of a piston ring.
7. Repeat process of measurement with a ring established in the top part of the cylinder and compare results of measurement to technical requirements.
8. Repeat operation of check for each ring in the first cylinder, then for rings in other cylinders.
9. Establish piston rings on pistons in the same way, as well as at removal (the Arrangement of piston rings fig. see the piston).
10. First of all it is established маслосъемное a ring which consists of three separate elements. Establish a dilator маслосъемного rings in a piston flute, then consistently establish top and bottom маслосъемные rings.
11. Establish компрессионное a ring № 2 so that the label at an end face has been directed upwards (the Arrangement of label R or N fig. see a piston ring). Do not mix the first and the second компрессионные a ring as they have a various profile.
12. After installation of piston rings on the piston check up ease of moving of a piston ring in a piston flute.
13. Establish locks of piston rings on the piston how the Arrangement of locks of piston rings on the piston is shown on fig.
