3.1.3.4. Valves
THE GENERAL DATA

The prevention

Final valves of the 6-cylinder engine capacity to 174 h.p. for heat-conducting path improvement are filled by sodium. It is impossible to send these valves at once in a breakage as because of sodium presence there is a danger of explosion at a meltdown. Application 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 repair AUDI. If it is impossible, before sending in a breakage it is necessary to take following measures: ножовкой on metal cut a core of the valve and throw both parts in the big tank filled with water. As a result of promptly coming chemical reaction натриевое filling burns down, thus it is necessary to recede back and to protect eyes.


Removal

PERFORMANCE ORDER
1. Remove a head of cylinders.
The 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 corresponding укладочную a board.


2. Remove a camshaft.
3. Tarelchatye pushers mark and pull out.
The prevention

Tarelchatye pushers stack a working surface (the camshaft party) downwards.


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 маслосъемный a cap.
8. The bottom plates of springs of valves – the marksman – remove by means of special tool V.A.G-3047 or HAZET 791-5/791-2.

Installation

PERFORMANCE ORDER
1. Before installation of valves check up and if necessary дообработайте or grind in saddles of valves.
The prevention

New plates of springs of valves at a bottom edge of an aperture 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 necessarily replace маслосъемные caps of cores of valves.
5. A valve core easily grease and insert the valve.
6. Dress new маслосъемный a cap.
The prevention

If to carry out assemblage without the plastic directing plug маслосъемные caps are damaged! The engine will spend a lot of oil.


7. Establish valve springs. If valve springs are replaced, both simultaneously.
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. Valve springs compress by means of a stripper of springs of valves and insert crackers so that they have lain down in grooves of a core of the valve. A stripper of springs ослабьте also insert the following valve.
10. Check up an axial backlash of a camshaft.
11. All тарельчатые pushers grease with engine oil and according to marks insert into apertures.
12. Establish a camshaft.
13. Replace a sealing lining of a head of cylinders, establish a head of cylinders.
