E46 series BMW 3

1 — the Candle head - Is equipped with the special elastic loose leaf excluding possibility of casual damage of a porcelain insulator at a reversing of a candle.
2 — the Dinamometrichesky key - without entering into number of obligatory tools, provides a reliable guarantee of correctness of effort of a tightening of spark plugs.
3 — the Ratchet drive - Is applied in a set with a candle head and a dinamometrichesky key.

4 — the Extension piece - Depending on model and a complete set access to spark plugs can be limited by its auxiliary units in various degree therefore use of extension pieces of the corresponding form and a design will allow to facilitate procedure performance considerably.
5 — the Adaptation for measurement and correction of interelectrode gaps of spark plugs - Is issued some this sort of types of tools - make sure that the tool is completed shchupy, to gaps of candles of your car corresponding on the size.

4 Candle gap is checked by insertion of a measuring instrument of the necessary thickness between electrodes on the candle end. The gap should correspond specified in Specifications. The delay should concern each of electrodes only. If the gap does not correspond to norm, slightly turn in the bent part of an electrode by means of a regulator with notches before achievement of necessary size of a gap.

At adjustment of a gap of a new candle turn in only the basis of an electrode of weight, without touching its end. If the electrode of weight is displaced rather central electrode, by means of a regulator with notches level them. Check a porcelain insulator on existence of the cracks indicating those, it is necessary to replace a candle.

Replacement of candles should be made only on cold or slightly warm engine. If candles are turned out on the hot engine, the carving in openings of a head of the cylinders executed from light metal can be damaged.

8 Disconnect the cable channel at the lower part of the case of the filter-2-, having opened clips and take out a cable.

11 Hook a screw-driver and remove covers of bolts of fastening (an arrow on an accompanying illustration), turn out two bolts being under them.

13 Unscrew fastening bolts at each coil of ignition, carefully take out coils.

Pay attention to tapes of grounding of a cover of a head of cylinders at coils of cylinders 1 and 6. At installation they should be again fixed on the former places.

Thus do not warp a key not to damage a ceramic insulator.

If available there is no dinamometrichesky key, tighten new spark plugs on a corner 90 ° (1/4 turns). The candles which were in the use should be tightened only on a corner 15 °.

21 Fix the tire of weight-3-connecting plates of coils to a forward bolt of the coil of ignition. The tire of weight-1-cable mines should be connected by bolts to a connecting plate of-2-spark plugs.

In the presence of carving damages under spark plugs it is necessary for restoring. For this purpose there is the corresponding tool and a repair kit, for example, BERU firms. The special drill drills an old carving for what to remove a head of cylinders it is not necessary. Then in a head the new carving is cut and the candle with a special carving insert is rolled. The insert sits reliably and tightly.
