6.4.1. Maintenance service of the distributor of ignition
The distributor cover is necessary for cleaning through certain time intervals inside and outside to remove the coal rests, a dust and a moisture. Thus to clear and a distributor rotor. For cleaning to use the rags moistened in gasoline. Simultaneously it is necessary to check up a distributor cover on presence of cracks.
The distributor rotor is subject to replacement if contacts were erased (to establish a rotor with designation R1). Brass contacts cannot be ground in no event a file or to grind.
External surfaces of all wires of a high voltage should be kept clean, without oil and moisture traces to provide reliable conductivity of the electric power in ignition system.
Periodically it is necessary to take out all wires from the ignition distributor, to clean and supervise the ends of connections. Wires cannot be shortened to remove the poor-quality ends, it is necessary to replace them always. The new wire should be got only according to number of the spare part for the corresponding engine.
If the engine works unreliably and it is supposed that the matter is that malfunction of system of ignition, that, probably, the reason consists available defect in the Hall gauge. In many cases it is connected with giving of pressure which can be checked up by means of the voltmeter. For this purpose it is necessary to execute the following:
- To connect to the electric system the voltmeter according to the instruction of the manufacturer. Ignition should be switched off;
- To take out from a socket being on a lateral face of the distributor of ignition the large tip;
- To include ignition;

- To connect test tips of the voltmeter to 130
contacts of the tip specified in fig.
and to define the pressure indication. It should make not less than 9 Century Otherwise to repair the distributor of ignition or to replace it.
