The ignition distributor

The distributor of ignition of the 5-cylinder engine in the disassembled kind

1 – бегунок the ignition distributor;
2 – a dustproof cover;
3 – a cover of the distributor of ignition;

4 – the tip;
5 – the punched diaphragm;
6 – the Hall gauge.

To open the ignition distributor: to wring out a screw-driver fixing скобы (arrows), to lift a cover of the distributor (4) from the case (3), to remove бегунок the distributor (1), to remove a dustproof cover (2).


ВМТ – position of the distributor of ignition: the contact payment бегунка the distributor should be opposite to a mark on the brink of the case (arrow). A mark it is visible at the removed dustproof cover.

Models with 4 and 5-cylinder engines

The ignition distributor is in a sense words two-level. At each level various works are made:

  • In a high-voltage element бегунок the distributor distributes an ignition impulse on candles.
  • At the bottom level of the distributor the gauge of the Hall causing operating impulses is located.

Dismantling of the distributor of ignition

 PERFORMANCE ORDER

  1. To wring out metal fixing скобы covers by means of a screw-driver.
  2. To disconnect a wire of "weight" from shielding.
  3. To uncover the distributor, high-voltage wires remain connected.
  4. To remove бегунок the distributor, to take out the dustproof cover located more low.
  5. At installation to insert a dustproof cover so that the directing ledge has entered into a groove on edge of the case of the distributor.
  6. At бегунка the distributor there is an inflow which enters into dredging on a distributor shaft.
  7. The distributor cover also is supplied by inflow as protection against displacement, it should enter into cut on the distributor case.

Check of the distributor of ignition

 PERFORMANCE ORDER

  1. To uncover the ignition distributor. It should be pure both inside, and outside that the current-carrying touch from a dirt, products of a friction or a moisture did not take away a power-current from ignition system.
  2. Contact coal in the middle should be smooth and shining, to move without jammings and jammings.
  3. Бегунок the distributor should not be scorched on a contact uvula and on заливочной to weight помехоподавляющего the resistor between average contact and a uvula.
  4. Correctly chosen бегунок the distributor should have marks R1.
  5. Strips as from a graphitic pencil, on a distributor cover are traces of leak of a current which have burnt out these strips because of a dirt or a moisture.
  6. Temporarily it can be corrected, if сцарапать their screw-driver or a knife and to cover from above with a layer of glue, nail polish or, for want of something better, simply lipstick.

Removal of the distributor of ignition

 PERFORMANCE ORDER

  1. Removal: to establish the first cylinder in position position ВМТ of the moment of ignition, Engines see the head.
  2. To uncover the ignition distributor.
  3. To turn out a bolt on distributor fixture (below at the basis) to remove the ignition distributor.
  4. Installation: distributive and cranked shaft still should be in position ВМТ to (check).
  5. Only models with the 4-cylinder engine: the cut at an end face of a shaft of the oil pump is necessary for establishing in an aperture of the distributor of ignition to in parallel cranked shaft.
  6. To turn the distributor platen so that a contact payment бегунка the distributor has coincided with a mark on the brink of the distributor case.
  7. To insert the ignition distributor, if necessary to turn its case, before coincidence to a mark. In summary to adjust ignition, see in the end of the head.
