2. The overhaul of tungsten contacts ablation on riveting loose or bracket set screw loose.
First, open the distributor cap, the first is visual inspection of the condition of tungsten rivet and contacts bracket set screw loose situation, and then, and then pull the two tungsten contacts back and forth. If the tungsten contacts are loose, then: you should remove tungsten contacts, re-riveting, to make it no loose, or replacement tungsten contacts directly.
If the tungsten contacts bracket set screw is loose, then tighten it.

3. The overhaul of the skew and offset condition of contact surface.
First, open the distributor cap, the first is visual inspection of the offset, skew situation.
If the contact surface offset, then: You can adjust the gasket of active tungsten contact arm.
If the contact surface of tungsten contacts has skew or excursion, then: You can use pliers to twist tungsten contacts frame to correct.

First of all, you should add appropriate proportion of nitric acid (8 mol / L) to scrapped silver tungsten points, and then heat them. You should filtrate after the above process, besides, the filtrate and scrubbing solution could be used together to prepare ultra-fine silver powder. Then, you should smash and sieve the residue after drying them.

Then, you should put the materials after first silver leaching process into the sintering furnace, and sinter 2h at a temperature of 500 ℃.

At last, you should wait until it cooling, and add nitric acid (8mol / L) to carry out secondary silver leaching, then cooling and filtering.

1. The overhaul of tungsten contacts gap in distributor.

Open the lid of the distributor, shake and rotate the engine, so that tungsten contacts of the distributor is in good state, then, check the gap among tungsten contacts, to see whether it is less than 0.37mm, if less than 0.37mm, we need to check the extent of tungsten contacts ablation, otherwise, you do not need to check.

If the extent of tungsten contacts ablation is very serious, then: Firstly, put on gloves, remove the tungsten contacts, and put it on a flat stone; then, get some oil in your hand, then pull back and forth parallel to polish tungsten contacts, to prevent partial wear during, you should not use hand to swing it .

If the extent of tungsten contacts ablation is not serious, then: using platinum sand bar or fine sandpaper to smooth ablation. When using fine sandpaper, fine sandpaper can be turned over, so its sand finish is outwardly facing to polish tungsten contacts, and then be turned back, and erasing the dirt left by milling until tungsten contacts is clean.

Firstly, adding a certain amount of nitric acid (8 mol / L) to scrapped silver tungsten contacts, and then heating it. After that, filtration, and the filtrate and scrubbing solution can be used together for the preparation of ultra-fine silver powder. Then, smashing and sieving the residue after drying.

Secondly, put the materials after first silver leaching process into the sintering furnace, sintering 2h at a temperature of 500 ℃.

Finally, cooling, and adding nitric acid (8mol / L) to carry out secondary silver leaching, then cooling and filtering.
