BMW 3 series E46

1 — the Candle head - Is equipped by 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 the complete set with a candle head and динамометрическим a 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 application of extension pieces of the corresponding form and a design will allow to facilitate procedure performance appreciably.
5 — the Adaptation for measurement and updating of interelectrode backlashes of spark plugs - Is issued some this sort of types of tools - make sure that the tool is completed щупом, to backlashes of candles of your car corresponding on the size.

4 Candle backlash is checked by insertion of a measuring instrument of the necessary thickness between electrodes on the candle end. The backlash should correspond specified in Specifications. The delay should concern only each of electrodes. If the backlash 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 backlash.

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

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

8 Disconnect the cable channel at the bottom 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 which are under them.

13 Turn away bolts of fastening at each coil of ignition, cautiously 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 is not present динамометрического a 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 tyre of weight-3 connecting plates of coils to a forward bolt of the coil of ignition. The tyre of weight-1 cable mines should be connected bolts to a connecting plate-2 spark plugs.

In the presence of carving damages under spark plugs it is necessary for restoring. For this purpose there is a corresponding tool and the repair complete set, for example, firms BERU. 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.
