1.3.3.8. Replacement of spark plugs (SOHC engines)

GENERAL INFORMATION

The correct functioning of spark plugs – one of the most important conditions of effective operation of the engine. It is necessary, that on the engine spark plugs only the ordered type were established. At the serviceable engine cleaning of spark plugs – rare operation.

Tools necessary for vyvinchivaniye of a spark plug and correction of an interelectrode gap

 


Measurement of a gap of a spark plug by a wire template

 


Measurement of a gap of a spark plug shchupy

 


Vyvinchivaniye of a spark plug

 


PERFORMANCE ORDER
1. Mark high-voltage wires in figures from 1 to 4 (the 1st cylinder is located from a gear belt) and remove high-voltage wires from spark plugs.
2. Clear candles, using a brush, the vacuum cleaner or a stream of the compressed air that will exclude dirt hit in engine cylinders after a vyvinchivaniye of spark plugs. Unscrew candles, using a candle key (see spark plug Vyvinchivaniye's fig.).
3. Visual control of a working part of spark plugs can show an engine condition. If the nasal part of an insulator of spark plugs pure and white, without a raid, it testifies to too poor mix. It also specifies that the candle too hot, that is heat from the central electrode is taken away slowly. If it so, is necessary to adjust structure of a fuel mix or to replace a candle.
4. If the nasal part of an insulator is covered with a black raid, it means that a mix too rich. If the raid black and oily, it testifies to wear of the engine and need of its check and repair. If the nasal part of an insulator is covered with a light brown raid, the structure of a mix is optimum and the engine is in a good condition.
5. The interelectrode gap of a spark plug is of great importance, as at too big and at too small gap the size of a spark that leads to decrease in overall performance of the engine changes. The gap should correspond to technical requirements always. Check of a gap is carried out by a wire template or shchupy (see fig. Measurement of a gap of a spark plug by a wire template, Measurement of a gap of a spark plug shchupy). Korrektirov a gap is carried out by a podgibaniye of a lateral electrode. The central electrode by no means cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation.
6. For a podgibaniye of a lateral electrode of a candle it is necessary to use the special tool.
7. Before spark plug installation in the engine, check, that the carving was pure and all threads of a carving whole.
8. Screw in spark plugs by hand and then tighten them the demanded moment.
9. Connect to spark plugs high-voltage wires.
