Replacement of candles ignition/check of electric contacts The special tool will be required:
- Candle key.
- It is in addition recommended to buy special nippers, for example, of HAZET 1849 for simplification of removal of tips of candles.
The following spare parts have to be bought:
Removal
|
|
- To disconnect all tips of candles, at the same time it is necessary to pull for plugs, but not for cables. Above-mentioned nippers facilitate removal.
- To blow niches of candles compressed air that by the removed candlelight dirt could not get to openings.
- To turn out candles a candle key and to check a condition of candles (appearance). In the presence of some experience it is possible to draw conclusions on a condition of the engine from this:
|
|
Electrodes and insulators
Average-gray — the correct work of a secha of ignition and quality of mix
Black — mix too rich
Light gray — mix too poor
Are greasy — interruptions in work of the corresponding candle or low insulation of piston rings (to check a compression).
|
|
- To check insulators of candles for superficial currents of leak. Superficial currents leave thin, uneven marks on a surface. Perhaps it is required to replace untight tips of candles.

|
Installation
|
|
|
|
- Before installation to check distance between electrodes by means of the flat probe.
|
- At new candles the distance between electrodes is, as a rule, established correctly, see the Head Sistem of ignition, the Section of the Candle for MAZDA 323.
|
|
- For adjustment of distance between contacts it is necessary to turn in a weight electrode. For this purpose there is simple, practical adaptation, otherwise to knock on a weight electrode. At a podgibaniye to rest the small screw-driver against a candle carving, at all not against the central electrode as differently it will be damaged.
|
- To clear a carving on candles a pure rag.
- To screw in spark plugs a hand to a prileganiye to a head of cylinders.
| At the same time not to warp a candle. |
- To tighten spark plugs with effort of 20 Nanometers.
| If there is no dynamometer key, to tighten new spark plugs a candle key on 90 ° (1/4 turns). To tighten the candles which were in the use only on 15 °. Too strongly tightened candles can break or damage at a vyvinchivaniye a carving in a head of cylinders. In this case to make repair of a carving repair inserts of UTC or Heli - Coil. |
- To connect tips of candles according to an order of ignition 1-3-4-2.
- To check durability of landing of tips of candles and cables of ignition.
|
|
Check of electric sockets
|
|
- To check durability of landing of all electric sockets on the ignition coil.
- To replace the burst plugs.
- To clear corroded contacts by a wire brush or a skin, if necessary to spray spray for contacts.
- Contacts should not be damp, otherwise clear contacts and spray spray for contacts.
- To bend cables of ignition and to check existence of cracks. If necessary to replace all cables of ignition.
