Numbering of bolts of a head of cylinders


Order of screwing up of bolts

Removal

PERFORMANCE ORDER
1. Disconnect a cable of weight of the battery.

The prevention

Electronic memory, for example, a radio receiver code is thus erased. Before battery switching-off it is necessary to read instructions in subsection 7.2.


2. Completely merge cooling liquid and collect it in a vessel.
3. Remove a reception pipe of the muffler.
4. Disconnect from a head of cylinders all hoses of system of cooling.
5. Remove the air channel.
6. Unscrew a heat-shielding plate of a final collector.
7. Unscrew a final collector.
8. Uncover heads of cylinders with a lining.
9. Establish the piston of 1st cylinder in position ВМТ.

The prevention

After that position of cranked and distributive shaft should not to change.


10. Remove a gear belt.
11. Ослабьте bolts of a head of cylinders in certain sequence for 3 passes (fig. Numbering of bolts of a head of cylinders see).
12. Ослабьте all bolts na1/2 a turn in the set sequence.
13. Ослабьте all bolts on 1 turn.
14. Turn out all bolts.

The prevention

The head of cylinders can be deformed or burst, if the order of easing of bolts is not observed.


15. Check up, that all hoses and the wires conducting from a head of cylinders to the engine and a body, have been disconnected.
16. Remove with the assistant a head of cylinders.

The prevention

After removal do not put a head of cylinders on a sealing surface, completely open valves thus can be damaged. Put a head of cylinders on 2 wooden бруска.


Installation

PERFORMANCE ORDER
1. Clear a head of cylinders and check up on deformation.
2. Check up water, oil and fuel hoses on damages and cracks if it is required replace.
3. Check up valves and saddles of valves on deterioration and damages.
4. Establish a lining of a head of cylinders so that apertures in the block of cylinders and in a lining of a head of cylinders have coincided.

The prevention

There are linings of a head of cylinders of a various thickness which are designated by 1, 2 or 3 notches on the brink. If the lining is replaced only, it is necessary to establish a new lining of the same designation necessarily. If the block of cylinders, pistons, rods and коленвал were replaced or under repair, the thickness of a lining should be chosen according to size выступания pistons (it is carried out in a workshop).


5. Put on a head of cylinders.
6. Cover bolts of a head of cylinders and прокладные washers with a thin layer of pure engine oil and screw in according to designations (fig. the Order of screwing up of bolts see). Watch, that the oblique party прокладных washers has been turned to heads of bolts. The equal party of a washer is turned to a head of cylinders.
7. Screw bolts of a head of cylinders a hand to прилегания with a fillet.
8. Then tighten bolts with 1 on 10 for 5 passes.
9. On each pass bolts should be tightened in the set sequence.
10. Tighten bolts with 1 on 10 with effort 40 Н.м.
11. Tighten bolts with 1 on 10 with effort 90 Н.м.
12. Completely ослабьте bolts with 10 on 1.
13. Tighten bolts with 1 on 10 with effort 40 Н.м.
14. Tighten bolts with 1 on 10 rigid key for one pass on 75 .
15. The measuring instrument of corners if this adaptation is not present for this purpose is required, tighten bolts with 1 on 10 with effort of 90 Nanometers.

The prevention

The tightening of bolts should be made with special carefulness. Bolts should be tightened necessarily for 5 passes. Before an inhaling it is necessary to check up accuracy динамометрического a key. Besides it is necessary to observe sequence of an inhaling precisely.


16. Establish a gear belt.
17. Establish a head of cylinders with a new lining, preliminary put sealing means for covers of bearings 1 and 5.
18. Put sealing means for opposite places of a cover of a head of cylinders.
19. Slightly tighten all bolts effort a maximum 4 Н.м.

The prevention

If bolts tighten too strongly, there can be thinnesses.


20. Screw a final collector with effort 20 Н.м.
21. Screw a heat-shielding plate of a final collector.
22. Establish the air channel.
23. Put on all hoses of system of cooling a head of cylinders and fix collars.
24. Establish a reception pipe of the muffler.
25. Connect a cable of weight of the battery.
26. Fill in cooling liquid.
