2.9.1. Check and adjustment of gaps of valves

GENERAL INFORMATION

The piston of the 1st cylinder in VMT of a step of compression

When the piston of the 1st cylinder is in VMT of a step of compression it is possible to check gaps of final valves of the 1st and 3rd cylinders, and also inlet valves of the 1st and 2nd cylinders

The piston of the 4th cylinder in VMT of a step of compression

When the piston of the 4th cylinder is in VMT of a step of compression it is possible to check gaps of final valves of the 2nd and 4th cylinders, and also inlet valves of the 3rd and 4th cylinders

Prevention

For adjustment of gaps of valves the special adaptation for an otzhatiya of pushers is required.

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Disconnect high-voltage wires (see subsection 2.8.3) and provide access to a cover of a head of cylinders, having removed all necessary details.
3. Blow sites near spark plugs the compressed air to remove all pollution which can get to the cylinder. Turn out spark plugs (see subsection 2.8.2).
4. Uncover heads of cylinders (see subsection 3.1.1.3).
5. Establish the piston of the 1st cylinder in VMT of a step of compression (see subsection 3.1.1.2).
6. When the piston of the 1st cylinder is in VMT of a step of compression, it is possible to check gaps of final valves 1 and 3rd of cylinders, and also inlet valves 1 and 2nd of cylinders (see fig. The piston of the 1st cylinder in VMT of a step of compression).
7. Measure shchupy gaps in valves. At a normal gap щуп should pass with small effort. Write down those gaps which do not correspond to norm. Later these data will be used for calculation of thickness of remote laying.
8. Turn the crankshaft on 1 turn and combine adjusting labels. Measure shchupy gaps in other valves. When the piston of the 4th cylinder is in VMT of a step of compression, it is possible to check gaps of final valves 2 and 4th of cylinders, and also inlet valves 3 and 4th of cylinders (see fig. The piston of the 4th cylinder in VMT of a step of compression).
9. After measurement of gaps turn the crankshaft so that the cam of a cam-shaft of the first valve which gap will be regulated, was directed vertically up, aside from a pusher.
10. Turn a pusher so that dredging was turned towards a candle. Then by means of pincers and a shovel of the adaptation wring out a pusher. Pincers of the adaptation to establish as it is shown in a picture, longer capture of pincers should press out the lower part of a cam of a cam-shaft, and short capture presses out the top, pushing part of a cam. Wring out a pusher, having compressed handles of pincers, then rest an adaptation shovel against a pusher, thereby holding him in the wrung-out situation, and remove pincers.
11. By means of a small screw-driver or tweezers get remote laying of a pusher. Keep in mind that the adaptation is completed with a wire hook clamp which puts on on a handle of pincers and allows to fix a pusher in the wrung-out situation at laying removal.
12. Get laying by tweezers or a magnet.
13. Measure by a micrometer thickness of the removed remote laying. Then by formulas given below determine thickness of remote laying at which the gap in the valve will correspond to the standard:
N= + + (A-V)
T – thickness of the removed remote laying
And – the measured gap
N–thickness of new remote laying
V–a demanded gap in between the valve and a pusher (it is specified in subsection 2.1)
14. Pick up laying so that the thickness of established remote laying was as it is possible closer to settlement. The manufacturer in the spare part delivers laying from 17 dimensional groups, the thickness lies in limits from 2,5 mm to 3,3 mm and differs on 0,05 mm (see the table Thickness and number of remote laying delivered in the spare part).

Prevention

The number of acquired laying can be reduced if carefully to measure thickness of each of laying and it is simple to trade places. Laying of a pusher of one valve at which the gap does not correspond to norm, can approach to a pusher of other valve.


15. Establish pincers of the adaptation as it is specified in drawing so that long capture of pincers pressed out the lower part of a cam of a cam-shaft, and short capture – the top, pushing part of a cam. Wring out a pusher, having compressed handles of pincers and establish new laying (thus keep in mind that it is possible to establish laying having put on handles of pincers a hook from an adaptation set). Check a gap between the valve and a pusher to be convinced of correctness of selection of laying.
16. Repeat procedure for other valves gaps in which did not correspond to norm.
17. Establish all removed details (candles, high-voltage wires, tips, etc.) upside-down.
