3.3.12.2. Installation and check of gaps in shatunny bearings
GENERAL INFORMATION

Arrangement of joints of piston rings

 1. Top kompressionny ring

2. Dilator of a maslosjemny ring

3. Bottom kompressionny ring

4. Top disk of a maslosjemny ring

5. Dredging (are turned to a forward part of the engine)

6. Bottom disk of a maslosjemny ring

Before installation of pistons assembled with rods the surface of the cylinder should be absolutely pure, the facet should be removed from edges of cylinders, and the cranked shaft is established in the block of cylinders.

PERFORMANCE ORDER
1. Wipe a back surface of the new top shatunny loose leaf and lay it in a place in a rod. Be convinced that the ledge on the loose leaf came into sample in a rod and lubricant openings (1) coincided. The loose leaf not to grease. Similarly establish in a rod cover the bottom loose leaf.
2. Place joints of piston rings according to the scheme.
3. Grease pistons and rings with pure oil for the engine, compress rings the adaptation, having left an acting site of the piston.
4. Turn the crankshaft to NMT in the first cylinder, oil cylinder walls for the engine.
5. Soriyentiruyte the piston so that dredging (1) was turned towards a forward part of the engine (2 – a ledge).
6. Carefully enter the lower part of the piston with a rod into the first cylinder against the stop adaptations in the block of cylinders. Slightly knock on the upper edge of an opravka for uniform contact to the plane of the block of cylinders.
7. Enter the piston into the cylinder, carefully tapping with the wooden handle of a hammer on the piston bottom. Big effort not to apply.
8. Draw a rod to a neck of the crankshaft and check a gap in a rod the bearing c the help of a piece of calibre (it is specified by an arrow). Procedure of check differs nothing from procedure for radical bearings (see subsection 3.3.9.3). Rotation of the crankshaft or the slightest hit of oil on loose leaves at measurements are not allowed.
9. Nuts of a cover of a rod tighten with the set moment.
10. Define gap size. If the gap does not correspond to norm, be convinced of lack of greasing and dirt and again check diameter of a neck and correctness of selection of the loose leaf.
11. Carefully remove the calibre remains, grease loose leaves and a crankshaft neck, establish a cover and evenly tighten nuts with the set moment.
12. Repeat these operations for other rods. Check freedom of rotation collected Kalevala.
13. After final installation of pistons with rods check freedom of rotation of the crankshaft.
14. Check axial люфт a rod (see subsection 3.3.8). Keep in mind that after installation of new details люфт a rod there can be less norm and polishing of rods is required.
15. Collect and establish the engine, being guided by appropriate sections
