3.5.16. Installation of piston rings
THE GENERAL DATA

Arrangement of piston rings and locks of piston rings on the piston of the diesel engine of 1,7 l

 1 – the top sealing ring

2 – the bottom sealing ring

3 – маслосъемное a ring

F – an adjusting label on a piston head

Arrangement of piston rings on the piston

  

Arrangement of locks of piston rings of petrol engines

 I – the top and bottom sealing rings

II – маслоотражательное a ring

Arrangement of locks of piston rings of the diesel engine of 2,0 l

 I – the top sealing ring

II – the second sealing ring

III – маслосъемное a ring

PERFORMANCE ORDER
1. Before installation of new piston rings check up a backlash in the ring lock.
2. Arrange pistons and piston rings according to cylinders in which they will work.
3. Establish the top sealing ring in the first cylinder and the piston bottom push it in the cylinder to the cylinder basis.
The prevention

The top and average sealing rings are various, an external surface of an average ring конусная.

4. Using щип measure a backlash in the ring lock.
5. Repeat process of measurement with a ring established in the top part of the cylinder and compare results of measurement to specifications.
6. If too small, it it is necessary to increase a backlash, сошлифовывая ring end faces.
7. If too small, it it is necessary to increase a backlash, сошлифовывая ring end faces.
8. If a backlash in the lock of a ring too big, check up correctness conformity of rings to your engine.
9. Repeat operation of check for each ring in the first cylinder and then for rings in other cylinders.
10. Establish piston rings on pistons in the same way, as well as at removal.
11. On the diesel engine of 1,7 l the top and bottom sealing rings differ and can be identified on labels on the top ring surface. The top ring has a square profile and the ring is noted by T.Vtoroe's letter has a conic profile and is noted by the letter 2Т. Marks on rings should be directed upwards.
12. After installation of piston rings on the piston check up лекгость перемещенияпоршневого rings in a flute of the piston and establish locks of piston rings.
