Prevention
Final valves of the 6-cylinder engine in capacity to 174 h.p. for improvement of a heat-conducting path are filled with sodium. It is impossible to send these valves at once in a breakage as because of availability of sodium there is a danger of explosion when melting. Use of these valves in quality of "the special tool", for example, a punch is similarly inadmissible. Therefore it is recommended to transfer these valves to workshop care on AUDI repair. If it is impossible, before sending to a breakage it is necessary to take the following measures: a hacksaw on metal cut a core of the valve and throw both parts into the big tank filled with water. As a result of promptly coming chemical reaction sodium filling burns down, thus it is necessary to recede back and to protect eyes.
Removal
| PERFORMANCE ORDER |
1. Remove a head of cylinders.
Prevention
If details of a drive of valves are used repeatedly, they should be established on the former places. That there was no shift of details by places, it is recommended to prepare the corresponding ukladochny board.
|
| 2. Remove a camshaft. |
3. Tarelchatye pushers mark and pull out.
Prevention
Tarelchatye pushers stack a working surface (the camshaft party) down.
|
| 4. Remove springs of valves. In workshops the special tool (V.A.G-2037) is for this purpose used. |
| 5. Crackers, and together with them and springs of valves it is possible to remove valves also by means of a standard stripper of springs of valves. For this purpose first of all should be removed, depending on circumstances, inlet or final branch pipes. |
| 6. Compress springs of the valve and take out crackers. Remove the top plate of springs of valves and a spring of valves. The valve take out. |
| 7. Remove a maslosjemny cap. |
|
8. The bottom plates of springs of valves – the shooter – remove by means of the special V.A.G-3047 or HAZET 791-5/791-2 tool. |
|
Installation
| PERFORMANCE ORDER |
1. Before installation of valves check and if necessary дообработайте or grind in saddles of valves.
Prevention
New plates of springs of valves at bottom edge of an opening for crackers in places have very sharp edges. Such edges can damage to (scratch) cores of valves. The damaged valves replace, from plates of springs of valves before installation remove sharp edges.
|
| 2. Insert the bottom plate of a spring of the valve. |
| 3. Remove sharp edges from a surface of a core of the valve, contacting to crackers. |
| 4. For reliability increase surely replace maslosjemny caps of cores of valves. |
| 5. A valve core easily grease and insert the valve. |
6. Dress a new maslosjemny cap.
Prevention
If to carry out assembly without the plastic directing plug, maslosjemny caps are damaged! The engine will spend a lot of oil.
|
| 7. Establish valve springs. If springs of the valve are replaced, both at the same time. |
|
8. Insert the top plate of a spring of the valve. The top plates of springs of valves have outside a wide facet – And – and a facet inside – Century. |
| 9. Springs of the valve compress by means of a stripper of springs of valves and insert crackers so that they lay down in grooves of a core of the valve. A stripper of springs weaken and insert the following valve. |
| 10. Check an axial gap of a camshaft. |
| 11. All tarelchaty pushers grease with engine oil and according to marking insert into openings. |
| 12. Establish a camshaft. |
| 13. Replace sealing laying of a head of cylinders, establish a head of cylinders. |
