Remove the slider by pulling it up

We install a new slider and cover in place.

We connect the high-voltage wires to the lid, observing the order of operation of the cylinders 1-2-4-3, starting from the output "1" counterclockwise.

The cover is installed in only one position.

When assembling, check the alignment of the lid protrusion with the slot on the distributor housing.

We remove the fillet from the rotor sleeve

We feed four to five drops of engine oil into the rotor hub

We install the filter, the slider and the cover of the distributor sensor

And take out the distributor

We install the distributor sensor in the reverse sequence

The slot in the thrust sleeve of the drive roller is offset relative to the axis of rotation and is combined with the coupling of the distributor sensor in only one position

Disassembly of the distributor sensor

Using the goatee, we push the pin out of the roller hole

And, removing the coupling with washers, we take out the roller assembly with a centrifugal regulator

Before assembling the distributor sensor, lubricate the roller and its bearings with CYATIM-201 or No. 158 grease, apply 1-2 drops of engine oil to the filter.

We assemble the sensor in the following order: we install a roller and a stator support in the sensor housing.

We put the thrust of the vacuum regulator on the support pin

We install the stator and, after making sure that the regulator rod has not jumped off the pin, we tighten the two stator mounting screws

Further assembly is carried out in reverse order

Check that the marks on the rotor and the coupling match, if necessary, turn the coupling on the roller by 180°

Repair of the current difference plate of the slider

When repairing a worn-out slider in the ignition distributor by soldering a brass strip onto a current-carrying plate, it is difficult to determine the required size from the axis of the slider to its edge.

If the strip turns out to be shorter– we will not get the effect of the repair, and if it is longer, the plate will touch the terminals of the lid.

To determine this size, before the repair, we put a piece of plasticine on the end of the current-carrying plate and, having installed the distributor cap, rotate the crankshaft.

Repair of the current difference plate of the slider

The excess plasticine is cut off by the conclusions, after which we measure the size "a".

Having soldered a strip of brass, we process its protruding end to a size 0.1 mm smaller than the value "a".

Glue the cover of the distributor breaker

If the cover of the interrupter-distributor is cracked on the way, and there is no spare (or suitable glue), you can glue it with garlic juice.

Rub the fracture site with a clove of garlic and squeeze the parts of the lid for one to two minutes, as when using ordinary glue.

Garlic "glue" is not afraid of high temperature in the engine compartment and has good electrical insulation properties.

You can ride with such a cover for quite a long time - with good bonding quality up to several hundred kilometers.
