1. Remove a weight wire from the accumulator. |
2. On the four-cylinder engine disconnect wires from spark plugs. |
3. On V6 engines merge cooling liquid from the cooling system, remove a casing of the air filter and other elements which interfere with removal of a cover of a head of the block of cylinders. |
4. Using compressed air, remove dirt from installation sites of candles that it after unscrewing of candles did not get to cylinders. Unscrew spark plugs. |
5. Uncover a head of the block of cylinders. |
6. Install the piston of the first cylinder in the top dead point in a compression step. |
|
7. Using a probe edge, measure gaps of valves and write down their values. (See figures 1-3) |
8. On four-cylinder engines turn a bent shaft on one whole revolution and repeatedly combine установоч ny tags. Check valvate gaps on other cylinders (See fig. 4). On four-cylinder engines at installation of the piston of the fourth cylinder in the top dead point in a step of compression check gaps of final valves of the cylinder No. 2 and No. 4 and gaps of inlet valves of the cylinder No. 3 and No. 4. |
9. On V6 engines turn a bent shaft on 240 ° clockwise and check a gap of the valves shown in fig. 5, 6. Further turn a bent shaft for 240 ° and check a gap of valves on other cylinders (See fig. 7). |
10. After measurement of gaps of valves turn a bent shaft of the engine in such situation that distribute a cam a telny shaft over the valve on which it is necessary to make adjustment was established up. |
11. Turn dredging in a valve pusher to a spark plug. Using the special tool, press a valve pusher down and record a pusher in this situation. Using tweezers or a magnet, take from a pusher an adjusting plate (See the drawings Use of the Special Tool for pressing of a pusher of the valve, Fixing of a pusher of the valve in the pressed situation, Removal of an adjusting plate from a valve pusher). |
|
12. Measure by a micrometer thickness of an adjusting plate. For determination of the required thickness of an adjusting plate use the following formula: N = T + (A – V),
T – thickness of an old adjusting plate, And – a valve gap, N – thickness of a new adjusting plate, V – the required valve gap. |
12. Choose an adjusting plate thickness of which is closest to calculated. There are adjusting plates from 2,500 to 3,300 mm thick with a step of 0,05 mm. |
13. Install the device for pushers of valves with the long sponge covering bottom edge of a pusher and with the lower shorter sponge covering the upper edge of a pusher press a pusher down, having squeezed handles of adaptation and establish an adjusting plate of the required thickness. Remove the device for installation of an adjusting plate and measure a valvate gap. |
14. Replace with the Analochichny image adjusting plates on which on valves adjustment is required. |
15. Establish spark plugs, a cover of a head of the block of cylinders, high-voltage wires and other earlier removed elements. |
