Wires of a high voltage of the distributor incorporate to spark plugs according to sequence of ignition in the engine of 1,6 l. By figures it is shown, to what cylinder there should be this wire (numbering system in front back). The letter "Z" designated the main wire of a high voltage to candles.

Engine in capacity of 74 kW

Distributor somewhat the two-storeyed. Each floor performs different work:

    In the top part the rotating finger of the distributor submits a high-tension current on separate spark plugs. In the lower part of the distributor the sensor of the Hall sending impulses of ignition settles down.

How to open the distributor


    Wring out a screw-driver metal fixing brackets of a cover. Disconnect the wire of the screen connected to weight. Uncover the distributor, the wire of a high voltage remains connected. Disconnect a distributor finger, remove the dustproof cover located under it. At installation a dustproof cover put so that its fixing ledge entered into a groove on the brink of the distributor case. On a finger of the distributor there is a welded-on ledge which enters into dredging of a shaft of the distributor. On a distributor cover also there is the welded-on ledge protecting from a prokruchivaniye which should enter into cut in the distributor case.

     Important: smooth out contacts of wires of ignition on distributor inside. The layer of an oxide causes ignition violations.

    The graphite contact brush in the middle should be smooth and brilliant, it is easy to be compressed and without jamming again to be unclenched. The finger of the distributor should not be melted into areas of a uvula of contact and over a filling compound of antinoise resistance between average contact and a uvula. On a finger of the distributor there should be «R1» designation. The strips reminding pencil, on a cover of the distributor are traces of burns from creeping currents which laid itself a way at the expense of dirt or dampness and left these burns. In this case as the temporary help it is possible соскрести their screw-driver or a knife and to cover with universal glue, nail polish or in emergency lipstick.
