4.21. Installation of pistons and rods, check of working gaps of bearings

GENERAL INFORMATION

Arrangement of locks of piston rings on the piston

PERFORMANCE ORDER
1. Clear a back part of the loose leaf and a place of its installation in a rod and a rod cover. Thus openings for greasing in a rod and the loose leaf should be combined.
2. Establish locks of piston rings on pistons how the Arrangement of locks of piston rings on the piston is shown in drawing.
3. Remove pieces of a rubber hose from hairpins of fastening of the bottom head of a rod.
4. Grease pistons and piston rings with pure engine oil.
5. Compress piston rings on the piston the special adaptation for compression of piston rings.
6. Turn a cranked shaft in the provision of the top dead point of the first cylinder and apply a thin film oils on cylinder walls.
7. Insert the piston with the adaptation compressing rings, into the top part of the first cylinder. Thus dredging on the piston should be directed towards a gear belt. 8. Using wooden whetstone or the hammer handle, press the piston into the cylinder.
9. Check combination of the bottom head of a rod with a neck of a cranked shaft. If necessary tighten the piston a rod and establish the bottom head of a rod with the loose leaf on a neck of a cranked shaft.
10. Check a gap of shatunny bearings.
11. Clear a back part of the loose leaf and a place of its installation in a rod and a rod cover.

12. For check of a working gap of the bearing of the bottom head of a rod use the Plastigage method. In this case использу ется a round plastic core which is compressed between the loose leaf and a neck of a cranked shaft. After removal of a cover of the shatunny bearing the deformed plastic core is measured by a special template which is available complete with Plastigage. Procedure for Plastigage use following. Establish without greasing rods on a cranked shaft. Necks of a cranked shaft and loose leaves should be absolutely pure and dry. Cut off some slices of a plastic core and establish them on each neck of a cranked shaft. Establish covers with the bottom loose leaves and tighten bolts of fastening the demanded moment.

13. In the course of gap measurement by the Plastigage method do not rotate a cranked shaft of the engine. Unscrew the bottom cover of a rod, remove it and to the deformed plastic core put the large-scale ruler printed on packing. Comparing width of the deformed plastic core with control width on a large-scale ruler, define gap size. In end carefully clear Plastigage traces - a material from loose leaves and a cranked shaft.
14. Apply a thin film engine oil on working poverkhno сти shatunny bearings and establish a rod on a neck of a cranked shaft. Establish the bottom cover of a rod and tighten nuts of fastening the demanded moment.
15. Similarly establish other pistons with rods.
