Check and compensation of spark plugs, check of a condition of high-voltage lines (petrol models)
|
|
You replace spark plugs only on cold or a little warm motor. If candles on the hot motor are pulled out, the work of a slice of the head of cylinders which is filled from light metal can be damaged. |
Spark plugs are replaced, depending on type, each 96 000 km or 160 000 km. Prior to work you prepare all necessary tools (before several producers of spark plugs special tools deliver for measurement of freedom of action of candles):
Key of candles of 16 mm, for example, HAZET 900AKF. 100 Mercedes Benz use for this purpose a key of candles 3122B.
HAZET 1849 which is in addition recommended to get special nippers, for example, which facilitate otworatschiwanije of candles. Mercedes Benz uses for this purpose a key of installation 3277A.
Depending on number of cylinders of the motor necessary quantity of spark plugs. The used spark plugs are listed in specifications. For each cylinder 2 of a spark plug are used.
The best way of compensation of spark plugs is a preliminary purchase of new candles, regulation of its freedom of action and compensation of each candle in turn. When purchasing candles it is very important to choose just those candles which are intended for the motor of your car. Information on them is provided in specifications.
Handy having new candles, you allow the motor completely that it cooled down prior to removal of old men. For this time it is possible to look at new candles on existence in them of defects and which check freedom of action of candles.
The freedom of action of candles is checked by means of adjustment of the measuring device of necessary thickness between electrodes to a candle at the end. The freedom of action has to correspond it is specified in specifications. The delay has to concern each of electrodes only. If the freedom of action of norm, a few podognite the bent part of an electrode by means of the regulator with notches up to achievement of necessary size of freedom of action does not correspond.
|
|
At regulation of freedom of action of a new candle of podgibajte only the weight electrode basis, the end without concerning. If the weight electrode concerning the central electrode is postponed, level by means of the regulator with notches them. Check the porcelain insulator for existence of cracks which designate on it, a candle it is necessary to replace it is necessary. |

1. Will leave ignition.
2. Exclude the cable pipeline (12). On motors of 120.980 cable pipelines at compensation of spark plugs it has to be excluded.
3. Accept a rubber condensation of a cover (A) and plugs of the line () (watch sopr. Illustration).
4. Accept ignition coils. On motors 104 you accept coils of ignition T1/1, T1/2, T1/3 with control incentives and high-voltage lines of ignition.
5. Exclude tops of spark plugs by means of soft proworatschiwanija. Check an internal part of Sharp WW lines for lack of a side spark (change of color) and check a condensation for absence of damage.
6. Wipe tops and produjte from compressed air.
7. Replace spark plugs. For prevention of damage of the work of a slice now of candle saworatschiwanija you use the rubber listener (internal diameter 5/16 duties), interested on its isolation center. In attempt of saworatschiwanija after the work of a slice the rubber listener will not begin proworatschiwatsja candles to damage on the insulator without allowing, the work of a slice.
8. Establish tops and you are convinced of correctness of its device. |

A, In — covers
21 — a spark plug
29/1 — a strengthening element |
|
|
|
1. Be lowered covers (A) and ().
2. Accept spark plugs (21).
3. Use the spark plugs recommended by the producer. Check freedom of action between electrodes of 0.8 mm. |
|
Check
|
|
| 1. Compare the taken-out candle with shown in the head the electric equipment of the motor. |
2. Check schtschupom interudaleny electrodes. The necessary value of freedom of action is given in specifications.
|
|
By new candlelight the interudaleniye of electrodes is correctly defined, as a rule. |
|
|
| 3. If the work of a slice of a candle has a damage, it is necessary to replace them. For this purpose there is the corresponding instrument and the offer of repair, including BERU. By means of specially swerla old opening of a slice can take place. It should not accept the head of cylinders for this purpose. After it in the head of naresana cylinders the new work of a slice can be and by means of a special insert of a slice the candle is screwed up. Inserts of a slice sit, of course, and densely. |
| 4. For the removal device between contacts of podognite the corresponding mass electrode. For this purpose you tap along with it a mass electrode. At podgibanii oboprite the small screw-driver over edge of the work of a slice. You do not lean at all on the central electrode as it is possible to damage it. |
|
5. Charge a few medsoderschaschtschego antimitnehmenden of structure on the work of a slice of a new candle. Establish a candle in the head of cylinders and screw up from her fingers before blow, then you delay with the help of the head of a key of candles. If it is possible, use a key for dinamometritscheski candle delay to be convinced that it is correctly defined. The effort of a delay of candles is made in the specification.

|
For prevention of a possibility of wwintschiwanija of a candle after the work of a slice you do not rise by them chwostowik a small piece of a rubber sleeve or the plastic listener. The flexible listener will be as it is universal - kardannyj a joint work, equating of a candle concerning network of candles, and guaranteeing if begins a candle of perekaschiwatsja, the hose on it will slip, without promoting to take down the work of a slice. |
6. Before accession to a candle you carefully watch the high voltage (WW) of the line at it on damages, corrosion of internal contact and you measure resistance. If it significantly passes 30 clots/m - you replace all offer of lines.
7. Include the line to a certain new candle, reusing the removing movement to themselves and in the plug including until it is not put on a candle up to the end.
8. Repeat the procedure described above for other spark plugs consistently to avoid a wrong adjunction of a candle of WW lines. |
