16.11.4. Replacement of spark plugs


Candles are established in a head of the block of cylinders on the left side.
We blow in a candle nest compressed air from the compressor or the pump to remove pollution.
We change candles in turn not to mix an order of connection of wires.

We remove a candle tip.

Candle key from set or a special head "on 21" we turn off a candle.

Before installation of a new candle we check a gap between its electrodes (see Adjustment of a gap between spark plug electrodes) and we are convinced that the sealing washer on the place and is not deformed. We wrap a candle at first "by hand", then we tighten a key (see Appendices).
