7.3. Spark plugs



Do not serve a spark plug on the hot engine.


1. Disconnect a wire from the negative plug of the storage battery.
2. Disconnect high-voltage wires.
3. The compressed air clear candles that will exclude dirt hit in engine cylinders after a vyvinchivaniye of spark plugs.
4. 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.


1. Connect a wire to the negative plug of the storage battery.
2. Connect a spark plug to a high-voltage wire.
3. Holding a spark plug special пассатижами with the isolated handles, connect the candle case to mass of the car.


Do not concern a car body during performance of the following operations.

4. The assistant should turn a cranked shaft of the engine a starter, thus between electrodes of a candle the steady strong iskroobrazovaniye should be observed.
5. In the absence of an ignition spark, or an ignition spark weak, check a condition and correct the following defects:
      – in the presence of a deposit clear or replace a spark plug;
      – at pollution by oil clear or replace a spark plug;
      – at wear or burning out of electrodes replace a spark plug;
      – at destruction of a ceramic insulator replace a spark plug;
      – at damage of a ring of a spark plug replace a spark plug;
      – at violation of an interelectrode gap in a spark plug, adjust a gap. Correction of 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. For a podgibaniye of a lateral electrode of a candle it is necessary to use the special tool.

Interelectrode gap of a spark plug:
TED: 0,7–0,8 mm
BFD: 1,0–1,1 mm


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

Inhaling moment: 25–30 N • m

2. Connect a high-voltage wire to a spark plug.

3. Connect a wire to the negative plug of the storage battery.
