|
Dismantling
Components of assemblage of a head of cylinders are presented on an accompanying illustration.
Components of assemblage of a head of cylinders
|
1. Take out pushers of valves and lay pushers as installation. 2. Remove forward and back elevating eyes of the engine. 3. Remove gauge ECT.
|
4. Remove levers of a drive of valves and arrange them as installation (address to an accompanying illustration). |
5. Remove valves. For this purpose: And. Compress a stripper a spring and remove 2 crackers; b. Remove a spring plate, a spring and its saddle; arrange details of each complete set as installation; c. Remove маслосъемные caps. |
|
Assemblage
|
1. Carefully clear all details and grease their rubbing surfaces with fresh engine oil.
|
2. Establish elevating eyes of the engine (address to an accompanying illustration). |
|
3. Establish a segment insert, preliminary having put on it hermetic (address to an accompanying illustration).
|
4. Establish the valve in an order, the return to a removal order. 5. Обстучите a plastic hammer an end face of a core of the valve. 6. Establish pushers of valves and adjusting washers. Be convinced that pushers freely rotate by hand.
|
7. Establish levers of valves and make sure of smoothness of their course (address to an accompanying illustration). |
8. Establish gauge ECT. |
|
Installation
|
1. Interfaced surfaces of heads of cylinders and their covers should be absolutely pure and dry. By means of a scraper remove all traces of old hermetic and fragments of the destroyed lining, then wipe surfaces the rags moistened in acetone. Presence on interfaced surfaces of traces of oil can lead to development of leaks.
|
2a. Measure size of the maximum ledge of each piston in two points, calculate arithmetic-mean value of a ledge and compare it to requirements of Specifications (address to an accompanying illustration). |
|
2b. If necessary replace the piston in gathering with a rod (address to an accompanying illustration). |
|
3. Define the greatest value of a ledge of the piston and in conformity with it pick up a lining of a head of cylinders, being guided by the table resulted more low.
|
As spare parts linings №№ in 1, 3 and 5 thickness according to 0.85 – 0.95, 0.95 – 1.05 and 1.05 – 1.15 mm are delivered only. |
Lining number is defined on number of cuts on it (address to an accompanying illustration). |
Ledge поршя, mm |
Lining number |

1 |
0,226 – 0,325 |
3 |
Not less than 0,326 |
5 |
4. Establish the piston of the first cylinder in position ВМТ.
|

Lay a lining of a head of cylinders on the block of cylinders, grease a carving and the bottom part of heads of bolts of fastening of a head of cylinders with impellent oil and tighten bolts by hand. Then tighten bolts in the established sequence with effort of 69 Nanometers then hold on them twice on 90 hailstones., observing sequence (address to an accompanying illustration).
|
Bolts «B» (№№ 21, 13, 5, 4, 12, 20) have length of 133.5 mm, and bolts "And" (others) – 121.5 mm. |
|
|

|
Establish the loose leaf in width in the bearing №1, and loose leaves in width of 20 mm – in other bearings. |
|
|
6b. Establish a persistent ring of a camshaft (address to an accompanying illustration). |
|
7. Lay a camshaft in a head of cylinders шпоночной a flute upwards (address to an accompanying illustration).
|
8. Establish the top loose leaves in covers of bearings. 9. Establish covers of bearings, коромысла, clips of atomizers and an axis коромысел in gathering.
|
10. Tighten 14 bolts of fastening of covers of bearings in certain sequence and 7 bolts "And" (address to an accompanying illustration). |
11. Establish atomizers. 12. Check up and if necessary adjust клапанные backlashes.
|
13. Remove old hermetic from an interfaced surface of a back cover of a belt, put new hermetic and establish a cover (address to an accompanying illustration). |
14. Establish pulleys and a gear belt.
|
15a. Fill in the landing grooves segment rubber stoppers, having made sure of their suitability (address to an accompanying illustration). |
|
15b. Grease with their hermetic (address to an accompanying illustration). |
16. Lay a lining of a cover of a head of cylinders, establish a cover with 12 new sealing washers and tighten bolts of its fastening with effort of 6.5 Nanometers. 17. Establish a back arm of the engine. 18. Collect a final collector in sequence, return procedure of its dismantling. 19. Establish linings, турбокомпрессор and assemblage of a final collector. 20.
