| 1. Remove a head of the block of cylinders and clear it of a dirt. |
|
2. Using the adaptation for compression of a spring of the valve, compress each spring and remove crackers from a valve end face. Remove the adaptation for compression of a spring and take a plate of a spring and a spring. Flat-nose pliers, being careful, take маслоотражательный a cap from a valve rod. Take the bottom plate of a spring. Keep in mind that the bottom plates of a spring inlet () and final () the valve differ. |
| 3. When the valve spring is compressed also a spring plate does not act in film from crackers, it is necessary to strike a hammer through wooden брусок on a spring cup that will lead to clearing of crackers. |
| 4. Take the valve through the combustion chamber. Each valve store in a separate polyethylene package together with a spring plate, a spring, the bottom plate of a spring and crackers for their further installation on the places. |
| 5. Check up a condition of saddles of valves. If they are burnt, worn out or have defects, it is necessary to replace them. If deterioration of a saddle of the valve is insignificant, they are necessary for grinding in. Check up directing plugs of valves on deterioration, inserting into them a core of the valve and moving it aside. Moving should be insignificant. |
| 6. Using a metal ruler and probe, check up planeness of an interfaced surface of a head of the block of cylinders. At неплоскостности more than 0,1 mm it is necessary перешлифовать a head, thus its height should correspond to requirements. |
| 7. Check up a condition of nests of pushers in a head of the block of cylinders. If nests of pushers are worn out, replace a head of the block of cylinders. Also check up a condition of apertures in a head of the block of cylinders for oil giving to hydraulic pushers. |
| 8. On engines with the big term of operation, probably, pollution have got in the hydraulic valve, the poet recommends to assort and clear each time at dismantling of a head of the block of cylinders hydraulic pushers. Spare parts to hydraulic pushers do not go on sale, therefore at failure of any detail of a pusher it is necessary to replace a hydraulic pusher in gathering (fig. of the Detail of a hydraulic pusher see). |
| 9. Remove the bearing from the top part of the cylinder of a hydraulic pusher, thus do not deform it. Take from the cylinder of a hydraulic pusher плунжер and a spring. An edge of a small screw-driver, being careful, uncover the basis плунжера and take a spring and a ball. |
| 10. Clear details of a hydraulic pusher kerosene or solvent and wipe or dry up pusher details. Check up a condition of springs and, in the presence of damages or deformation, replace a hydraulic pusher in gathering. |
| 11. Grease details of a hydraulic pusher with pure engine oil and collect a pusher. |
|
12. Turn плунжер and insert a ball (1) into an aperture (2) in the basis плунжера. |
|
13. Establish a small spring (1) in a cover плунжера, then, being careful, establish a cover with a spring. Check up that the spring draws in a ball (2). |
|
14. Using a screw-driver edge, press a cover into a flute плунжера. |
|
15. Establish the big spring on a cover плунжера. |
|
16. Establish плунжер with a spring in the cylinder of a hydraulic pusher. |
|
17. Establish the bearing (1) on the top part плунжера and, being careful, hands compress плунжер before accurate fixing of the bearing in a flute of the cylinder of a pusher (2). |
|
18. On some engines in a head of the block of cylinders the valve (it is specified by an arrow), stabilising pressure of the oil submitted to pushers of valves is established. For valve extraction unscrew a carving stopper and tap М10 take the valve from a nest. At installation of the new valve observe cleanliness that pollution have not got to oil channels. |
| 19. Grease cores of valves with engine oil and insert them on the places. The valve establish on those places where they have been ground in. |
| 20. Establish the bottom plate of a spring. |
| 21. In the complete set new маслоотражательных caps there is an adjusting plug which is established on a core of the valve and protects working edges маслоотражательных caps at their installation. Establish the adjusting plug on a valve core, lower маслоотражательный a cap in fresh engine oil and establish it on a valve core into place, being careful not to damage its working edges. For installation маслоотражательных caps use special metal оправку. |
| 22. Establish клапанную a spring and the top plate a spring. |
| 23. The special adaptation compress клапанную a spring and establish crackers in dredging of a core of the valve and grease them. Remove the adaptation for spring compression. Repeat this operation on other valves. |
| 24. With a hammer through wooden брусок knock on an end face of a core of the valve that all elements of the valve were accurately established on the places. |
| 25. On engines 1,6 (16 SH), 1,8 and 2,0 l at the removed head of the block of cylinders replace a sealing ring of a casing of the thermostat. |
