Replacement of spark plugs (each 48 000 km (30 000 miles) run, or times in two years)

Open a cowl and mark candle wires for a guarantee of their correct connection at assemblage.

In most cases the number of spark plugs of tools necessary for replacement includes the candle head equipped with a soft insert of the employee for prevention of damage of a porcelain insulator of a candle complete with a ratchet drive and a set of collars and extension pieces, and also the tool for measurement and adjustment of candle backlashes. Special tools for safe removal of tips of candle wires from shafts of candles Besides, are issued, however application of the given tool is not an indispensable condition of performance of procedure. For a tightening of new candles it is necessary динамометрический a key.

The tools necessary for product of replacement of spark plugs.

1 — the Candle head - Is equipped by the special soft insert serving for protection against damage of a porcelain insulator of a candle
2 — the Dinamometrichesky key - Though is not absolutely necessary tool, its use extremely is desirable at realisation of a tightening of new candles with demanded effort
3 — the Ratchet drive - Represents the standard metalwork tool applied to work with replaceable face heads
4 — the Extension piece - Depending on model and the car equipment auxiliary units, for вывинчивания candles can be necessary application of a various configuration of the extension pieces equipped карданными with hinges
5 — the Tool for measurement and adjustment of candle backlashes - Is issued a wide spectrum of a various design of such tools. Make sure available probeа a thickness demanded for your car

The best approach to performance of the given procedure of service of the car is acquisition of new candles beforehand. After realisation of adjustment of backlashes of a candle it is necessary to replace on one (passing to вывинчиванию old the second after installation new the first etc.). At purchase of new candles pay special attention on conformity of their standard size to technical characteristics of the engine of your car. The necessary information can be found on information шильде systems of decrease in toxicity of the fulfilled gases of the car (VECI), located under a cowl, in the operation manual on the car or in Specifications to the given Chapter. At different interpretations always it is necessary to give preference to data VECI.

 PERFORMANCE ORDER

  1. Before starting removal of candles, wait full cooling of the engine. Take advantage of time necessary for it for check of a condition and adjustment of backlashes of new candles.
  2. Measurement of a candle backlash is made by introduction between electrodes of a candle of a working part probeа a demanded thickness. The backlash size should correspond to data VECI. Щуп should slip between electrodes only with insignificant resistance. If the backlash demands adjustment, take advantage built in in a body of a measuring instrument of a regulator for подгибания a lateral electrode. If the lateral electrode is located not precisely over central, correct it by means of the same regulator. Check up a surface of a porcelain insulator of a candle on presence of cracks (in case of detection of those replace a candle).
  1. Manufacturers of spark plugs recommend to use for measurement of an interelectrode backlash probeом wire type - if probe does not slip between electrodes with easy resistance, carrying out of adjustment of a backlash is required.
  1. For backlash adjustment turn in a lateral electrode accordingly in one of the directions specified by arrows, operating extremely cautiously not to damage surrounding central electrode a porcelain insulator.
  1. After engine cooling remove a wire from the first spark plug. Pull only for a tip, and at all for a wire. It is desirable to take advantage of the special tool (the item "In most cases see...").
  1. At removal of a wire from a spark plug pull only for its tip, turning it thus.
  1. If there is a source of compressed air, take advantage of it for blowing from a candle niche of extraneous particles. For this purpose can approach and the usual bicycle pump not is worse. A problem of the given procedure is not to admit hit in the cylinder through a candle aperture of dust after candle removal.
  2. Put on a candle a candle head and unscrew a candle from the engine, rotating it counter-clockwise.
  3. Check up a candle condition at the help of a card of conditions of spark plugs [should be inserted somewhere into the Management]. The external condition of a candle can give the important information about about the general condition of the engine.
  4. Screw one of the prepared new candles in an aperture by hand against the stop, then tighten it with the help динамометрического a key (if that is available) or a ratchet drive. Good idea at наживлении candles will put on its shaft a piece of a fuel hose and to rotate a candle for it. It will allow to avoid damage of a carving to a case перекашивания a candle at its installation in an aperture as the hose at resistance increase will start to slip.
  5. Before installation of a tip of a wire on a candle shaft check up carefully its condition according to instructions Check of a condition of candle wires, covers and бегунка the distributor (each 48 000 km (30 000 miles) run, or times in two years) Has undressed.
  6. Connect a wire to a new candle, again making vrashchatelno-progress by a tip before its full landing to a candle.
  7. Repeat procedure for the remained candles, replacing them serially in order to avoid wrong connection of wires.
