Check of a condition and replacement of VV of candle wires, covers and distributor begunka


1. Check of a condition of VV of wires should be made each time at replacement of spark plugs (see. Section Check of a condition and replacement of spark plugs).
2. Check begins with external survey of isolation of wires at the working engine. Tire out the car in a dark, well ventilated room, start the engine and make sure of lack of an iskroobrazovaniye on wires. Iskroobrazovaniye is a sign of breakdown of isolation. Try not to touch moving components in an impellent compartment. Make necessary marks on replacement of defective wires, then let's to the engine cool down and start checks of a condition of a cover and a begunka of the distributor of ignition.
3. Check of candle wires is made serially in order to avoid violation of an order of their connection at assembly. Usually on isolation of firm wires there is the corresponding marking. In case of absence that, put it independently by means of an adhesive tape and a marker.
4. Disconnect VV a wire from a spark plug (best of all use the special tool). At all do not pull for a wire, only for its tip.
5. Examine internal walls of a tip. Corrosion is usually shown in the form of a fragile korkoobrazny raid of white color.
6. Pull a tip back on a shaft of the candle, make sure of density of its landing. In case of need again remove a tip and as appropriate turn in plugs in a rubber cover.
7. Pure rags wipe a wire on all its length, having completely removed from an isolation surface dirt and greasing traces. Examine wire isolation on existence of cracks, traces прогара and other damages. Try not to bend a wire under acute angles in order to avoid violation of integrity of veins of the conductor in isolation.

8. Disconnect a wire from the distributor, - again pull only for a tip, instead of for a wire. Check a tip on existence of signs of corrosion, estimate density of landing it on the plug. Again connect a wire to the distributor.

9. Operating in a similar manner, serially check a condition of all remained candle wires. Make sure of reliability of their connection to candles and distributor plugs.
10. In need of performance of replacement of VV of wires track that replaceable wires corresponded on the standard size to parameters of the engine of your car. In firm shops of automobile accessories and company service centers always it is possible to get sets of VV of the wires cut on length and equipped with tips ready to the use. Remove and replace wires serially in order to avoid violation of an order of ignition.

11. Having turned out fixing screws, uncover the distributor and attentively examine it both outside, and from within on existence of cracks, coal paths, traces прогара, weakening of contact connections and other damages.

12. Having pulled up, remove a begunok from a shaft of the distributor and examine it on existence of cracks and coal paths. Make replacement of defective components.

13. Good practice is replacement of a cover and a begunka of the distributor of ignition regardless of their condition each time at installation of new VV of wires. When using old components carefully smooth out contact surfaces of their plugs and measure resistive resistance of wires and a roof (see. Specifications to the present Chapter).
14. At installation of a new cover of the distributor transfer on it from old VV of a wire, connecting them it is strict in a former order, - try not to disconnect all wires at the same time, transfer them serially.

The order of ignition is specified in Specifications at the beginning of the present Chapter. On the majority of models the protective ledge (facing) of the plug of connection of a wire of a spark plug of the first cylinder on a cover of the distributor is as appropriate marked.
