Replacement of candles

Depending on style of driving of a candle it is necessary to change through each 30000–50000 km of run. In process of erosion of electrodes breakdown of a spark interval (size of erosion of 0,025 mm on each 2-4 thousand in km of run) is at a loss and requirements to pressure size on electrodes increase.

Candles it is necessary to replace everyone, numbering wires about a cover of the distributor of ignition.

1. Remove a wire of ignition from a candle, having pulled for a tip.
2. Clear candles and adjoining places that the dirt has not got to cylinders.
3. Turn out candles.
4. Check up a candle condition, compare to a scale of colouring of an insulator. On a condition of candles it is possible to define an engine condition.
5. Check up a backlash between electrodes of a new candle. If necessary adjust подгибанием the central electrode.
6. Slightly grease a candle carving маловязким with oil and screw candles by hand.
7. Tighten candles with the moment 20 Н.м.
8. Dress a wire and repeat the described procedure for each candle.

Check and replacement of high-voltage wires

At detection of damages of a wire are subject to replacement. If visible damages are absent, check up resistance of wires which should be within 9,6–22,4 clod. If resistance does not correspond to norm a wire replace. To replace wires follows separately, without breaking an order of a former arrangement. To bend wires it is not supposed.

The prevention

Cylinders are counted from a forward part of the car.
