3.3.16. Installation of piston rings
THE GENERAL DATA

Arrangement of piston rings on the piston

1. A maslosemnoe ring

2. An average sealing ring

3. The top sealing ring


Before installation of new piston rings check up a backlash in the ring lock.

PERFORMANCE ORDER
1. Arrange pistons and piston rings according to cylinders in which they will work.
2. 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.


3. Using щуп, measure a backlash in the ring lock.
4. Repeat process of measurement with a ring established in the top part of the cylinder, and compare results of measurement to specifications (subsection 3.3 see).
5. If too small, it it is necessary to increase a backlash, сошлифовывая ring end faces.
6. If a backlash in the lock of a ring too big, check up correctness of conformity of rings to the engine.
7. Repeat operation of check for each ring in the first cylinder and then for rings in other cylinders.
8. Establish piston rings on pistons in the same way, as well as at removal. At assemblage маслосъемного rings at first insert a spring and from above on a spring establish a ring so that the ring lock was from an opposite side from the spring lock. Check up that the average sealing ring is established by marks (a label a paint or a word "TOP") upwards (the Arrangement of piston rings fig. see the piston). Sealing rings establish so that their locks have been displaced concerning the lock маслосъемного rings on 120 every which way. Do not mix the top and average sealing rings since they have various profiles.
