1. Remove camshafts. |
2. Remove the spark plugs. |
3. Remove the protective coating on the wires of the engine bulkhead. |
| 4. Screw supporting web (2) with the movable member (7) to the bearings 5 and one of the camshaft or after the bearings 6 and 10 to 20 Nm |
5. Turn the piston at top dead center of the corresponding cylinder wrench with a nozzle. 4-cylinder engine: the TDC pulley pistons 1 and 4 are at TDC. When a match is 180-degree mark pulley with a base in the TDC mark are the pistons of cylinders 1 and 6. The 6-cylinder engine: the pulley TDC TDC are the pistons and cylinders 1 and 6. In case of coincidence of 120-degree mark pulley - pistons cylinders 2 and 5; at 240-degree mark - Piston 3 and 4. A warning When you rotate the crankshaft high lift control circuit that it is not jammed.

6. Hook the plunger arm. |
| 7. Pull out the pusher plate (3) of the rubber suction cup (diameter 30 mm), for example, HAZET 735-2. |
A warning Do not use a magnetic trap, as magnetized follower plate sliding surface and subsequently deposited on it fine metal chips, resulting in damage to the pusher and cam.
|
8. Lock the crankshaft. To do this, first gear and apply the parking brake. |
9. Install in the combustion chamber of the cylinder gauge pressure of at least 6 bar. To do this, screw in a connector hose (4) device for leak testing cylinder spark plug hole. If there is no leakage control device can be made suitable hose with an old spark plug. |
| 10. Bite electrode "weight" of the old spark plug (1). Break the ceramic insulator (2) with a screwdriver and break off, swinging back and forth, the middle electrode (3) and remove. Push the punch (about 3 mm) remains of the middle electrode with the glass (4) and a connecting pin (5). At the same time, hold the spark plug in a vice or use the appropriate vintonareznoy machine. |
A warning Do not damage the threads of the spark plug so as not to spoil the thread holes in the cylinder head.
|
11. Screw the spark plug into the corresponding cylinder, connect the hose to the discharge of air in the cylinder and set an overpressure of at least 6 bar. |
| 12. Install the pusher arm (9) with the pressure piece (5) on the valve spring plate. Place the piece of pressure and a movable piece in parallel. Moving parts lock bolt (8). |
13. Tighten the valve spring. A warning Do not compress the valve spring without compressed air, otherwise it may damage valves and pistons.
|
| 14. Details of the valve stem (14), remove the valve stem with tweezers (6) or a magnetic trap. |
15. Remove the valve spring plate (15) and a valve spring (17). |
| 16. Remove the valve stem seal (86) from the valve stem with special pincers, for example, HAZET 791-6. |
A warning Do not damage the stem and the valve guide.
|
17. Remove the valve spring plate (15) and a valve spring (17). |
18. If necessary, remove any burrs from the groove of the valve stem particulate emery cloth. |
19. Check the valve guide wear in fit them to the valve stem seals. Replace the valve guides (job for repair shops). |
