|Fig. 2.134. Components of the second stage of dismantling of the block of cylinders: 1–the balancing block (L3, L3 with the mechanism of change of phases of a gazoraspredeleniye); 2–rod cover; 3–bottom shatunny bearing; 4–top shatunny bearing; 5–rod and piston assembled; 6–piston ring; 7–cover of the radical bearing; 8–bottom radical bearing, persistent bearing; 9–cranked shaft; 10-top radical bearing, persistent bearing; 11-valve of a maslorazbryzgivayushchy nozzle; 12-block of cylinders; 13-adjusting laying
Remove the balancing block (engines L3, L3 with the mechanism of change of phases of a gazoraspredeleniye, see fig. 2.134
Uncover a rod. Before removal of a cover of a rod check a lateral gap of a rod (see further). Take out a shatunny bolt from a rod cover, striking on a bolt with a kapron hammer.
Remove the bottom shatunny bearing.
Remove the top shatunny bearing.
Remove a rod and the piston assembled.
Remove piston rings.
|Fig. 2.135. Order of weakening of bolts of fastening of a cover of radical bearings
Before removal of a cover of radical bearings check an axial gap of a cranked shaft. Weaken bolts of fastening of a cover of radical bearings for two or three receptions in an order specified in drawing 2.135
Remove the bottom radical and persistent bearings.
Remove a cranked shaft.
Remove the top radical bearings, persistent bearings.
Remove the valve of a maslorazbryzgivayushchy nozzle.
