Ignition distributor
Distributor of ignition of the 5-cylinder engine in unassembled form
To open the ignition distributor: to wring out a screw-driver fixing brackets (arrows), to lift a cover of the distributor (4) from the case (3), to remove the runner of the distributor (1), to remove a dustproof cover (2).
|
|
VMT – position of the distributor of ignition: the contact payment of the runner of the distributor has to be opposite to a mark on the edge of the case (shooter). A mark it is visible at the removed dustproof cover.
|
Models with 4-and 5-cylinder engines
The distributor of ignition is in a sense words two-level. At each level various works are performed:
- In a high-voltage element the runner of the distributor distributes an ignition impulse on candles.
- At the lower level of the distributor the Hall sensor causing the operating impulses is located.
Dismantling of the distributor of ignition
|
|
- To wring out metal fixing brackets of a cover by means of a screw-driver.
- To disconnect a wire of "weight" from shielding.
- To uncover the distributor, high-voltage wires remain connected.
- To remove the distributor runner, to take out the dustproof cover located below.
- At installation to insert a dustproof cover so that the directing ledge entered a groove on edge of the case of the distributor.
- The runner of the distributor has an inflow which enters dredging on a distributor shaft.
- The cover of the distributor is also supplied with inflow as protection against shift, it has to enter cut on the distributor case.

Check of the distributor of ignition
|
|
- To uncover the ignition distributor. It has to be pure both inside, and outside in order that the conducting raid from dirt, products of friction or moisture did not take away a high-tension current from system of ignition.
- Contact coal in the middle has to be smooth and brilliant, move without jammings and jammings.
- The runner of the distributor should not be scorched on a contact uvula and on the filling mass of the noise suppressing resistor between average contact and a uvula.
- Correctly chosen runner of the distributor has to have marking of "R1".
- Strips as from a graphitic pencil, on a cover of the distributor are traces of leakage of current which burned out these strips because of dirt or moisture.
- Temporarily it can be corrected if to stsarapat them a screw-driver or a knife and to cover from above with a layer of glue, nail varnish or, for want of something better, simply lipstick.

Removal of the distributor of ignition
|
|
- Removal: to install the first cylinder in situation the provision VMT of the moment of ignition, see the head Dvigateli.
- To uncover the ignition distributor.
- To turn out a bolt on fixture of the distributor (below at the basis), to remove the ignition distributor.
- Installation: distributive and cranked shaft still have to be in situation VMT (to check).
- Only models with the 4-cylinder engine: the cut at an end face of a shaft of the oil pump needs to be established in an ignition distributor opening parallel to a cranked shaft.
- To turn the distributor roller so that the contact payment of the runner of the distributor coincided with a mark on the edge of the distributor case.
- To insert the ignition distributor, if necessary to turn its case, before coincidence to a mark. In summary to adjust ignition, see at the end of the head.
