In the high-voltage element, the distributor slider distributes the ignition pulse to the candles.
At the lower level of the distributor is a Hall sensor that causes control pulses.
Disassembly of the ignition distributor
Pry out the metal fastening brackets of the cover with a screwdriver.
Disconnect wire «masses» from shielding.
Remove the distributor cap, high voltage wires remain connected.
Remove the distributor slider, remove the dust cover located below.
When installing, insert the dust cover in such a way that the guide lug enters the groove along the edge of the distributor housing.
Disassembled ignition distributor of a 5-cylinder engine:
1 - slider of the ignition distributor;
2 - dust cover;
3 — a cover of the distributor of ignition;
4 - plug;
5 - perforated diaphragm;
6 - Hall sensor.
The distributor runner has a lug that fits into a recess on the distributor shaft.
The cover of the distributor is also provided with a lug as a displacement protection, it must fit into the cutout on the distributor body.
Checking the ignition distributor
Remove the ignition distributor cap. It must be clean both inside and out, so that conductive deposits of dirt, friction products or moisture do not divert high voltage current from the ignition system.
The contact charcoal in the middle should be smooth and shiny to move without jamming or jamming.
The distributor slider must not be burned on the contact tongue and on the filling mass of the noise suppression resistor between the middle contact and the tongue.
A correctly selected distributor slider should be marked «R1».
The stripes, like from a graphite pencil, along the distributor cap are traces of current leakage, which burned out these stripes due to dirt or moisture.
This can be fixed temporarily by scratching them with a screwdriver or knife and topping them with a layer of glue, nail polish or, for lack of a better way, just lipstick.
Removing the ignition distributor
Removal: set the first cylinder to the TDC position of the ignition moment, see chapter «Engines».
Remove the ignition distributor cap.
Loosen the screw on the distributor (down at the base), remove the ignition distributor.
Installation: camshafts and crankshafts must still be at TDC (control).
4-cylinder models only: The slot on the end of the oil pump shaft must be installed in the distributor bore parallel to the crankshaft.
Turn the distributor shaft so that the contact plate of the distributor slider coincides with the mark on the edge of the distributor housing.
Insert the ignition distributor, if necessary, turn its housing until it matches the mark. Finally, adjust the ignition, see end of chapter.
