GENERAL INFORMATION

Arrangement of locks of piston rings on the piston

PERFORMANCE ORDER
1. Clear a back part of an insert and the place of its installation in a rod and a rod cover. At the same time openings for lubricant in a rod and an insert have to be combined.
2. Put locks of piston rings on pistons as it is shown in the drawing Arrangement of Locks of Piston Rings on the piston.
3. Remove pieces of a rubber hose from hairpins of fastening of the lower head of a rod.
4. Grease pistons and piston rings with pure engine oil.
5. Squeeze piston rings on the piston the special device for compression of piston rings.
6. Turn a bent shaft in the provision of the top dead point of the first cylinder and apply a butter layer on cylinder walls.
7. Insert the piston with adaptation squeezing rings into the top part of the first cylinder. At the same time dredging on the piston has to be directed towards a gear belt. 8. Using wooden whetstone or the handle of the hammer, press the piston into the cylinder.
9. Check combination of the lower head of a rod with a neck of a bent shaft. If necessary tighten the piston a rod and establish the lower head of a rod with an insert on a neck of a bent shaft.
10. Check a gap of conrod bearings.
11. Clear a back part of an insert and the place of its installation in a rod and a rod cover.

12. For check of a working gap of the bearing of the lower head of a rod use the Plastigage method. In this case to an ispolz the round plastic core which contracts between an insert and a neck of a bent shaft etsyatsya. After removal of a cover of the conrod bearing the deformed plastic core is measured by a special template which is available complete with Plastigage. The procedure for Plastigage use following. Establish without lubricant rods on a bent shaft. Necks of a bent shaft and inserts have to be absolutely pure and dry. Cut off several pieces of a plastic core and establish them on each neck of a bent shaft. Establish covers with the lower inserts and tighten fastening bolts the required moment.

13. In the course of measurement of a gap by Plastigage method do not rotate a bent shaft of the engine. Unscrew the lower cover of a rod, remove it and apply the large-scale ruler printed on packing to the deformed plastic core. Comparing width of the deformed plastic core to control width on a large-scale ruler, determine gap size. In conclusion carefully clear Plastigage traces - material from inserts and a bent shaft.
14. Apply a thin film of engine oil on working poverkhno st of conrod bearings and establish a rod on a neck of a bent shaft. Establish the lower cover of a rod and tighten fastening nuts the required moment.
15. Similarly install other pistons with rods.
