7.4. Check of spark plugs

1. Disconnect a wire from the negative plug of the storage battery. For a tip disconnect high-voltage wires from spark plugs.

The prevention

At a detachment of high-voltage wires from spark plugs pull for a wire tip, instead of for a wire as it can be damaged.

2. Compressed air clear candles that will exclude dirt hit in cylinders of the engine after вывинчивания spark plugs. Turn out a candle, using a candle key. For an exception of damage of a candle establish a candle key strictly along a candle axis.
3. Check up spark plugs on presence of following defects:

1) insulator damage;
2) the worn out electrodes;
3) a deposit;
4) lining damage;
5) an insulator condition on a spark plug tip.
4. A wire template check up an interelectrode backlash of a spark plug. Backlash updating is carried out подгибанием a lateral electrode.
The interelectrode backlash of a spark plug is of great importance, as at too big and at too small backlash the size of a spark that leads to decrease in an overall performance of the engine changes. The backlash should correspond to technical requirements always.

The central electrode in no event cannot be bent, as it can lead to breakage of an insulator and a candle exit out of operation. For подгибания a lateral electrode of a candle it is necessary to use the special tool.

Interelectrode backlash of a spark plug: 1,0-1,1 mm

5. Screw a spark plug in a head of the block of cylinders.

The inhaling moment: 20-30 Н•м
