Do-it-yourself repair of the thresholds of the VAZ 2106

In detail: do-it-yourself repair of VAZ 2106 thresholds from a real master for the site my.housecope.com.

The question of replacing thresholds is especially relevant for “our” VAZ cars. This is due to the low quality of the body metal, insufficient anti-corrosion treatment, as well as the harmful environment in which our cars have to live. By harmful environment, I mean road chemistry used to treat roads in winter, high humidity and bad roads.

Today I want to talk in detail about how do it yourself VAZ 2106 thresholds replacement... Thanks to this photo report, you can repeat the repair of the thresholds at home, in any case, I think this guide will be useful to someone.

First of all, you need to take care of the tool, I will list only a few, the most important of them:

  1. Welding machine.
  2. Electric drill.
  3. Bulgarian.
  4. New thresholds.
  5. Primer.
  6. Dye.

A few words about the welding machine. The fact is that it is advisable to cook the thresholds with a semiautomatic device in an environment of carbon dioxide.

  1. I started by repairing the door hinges, I will not describe how to do this, since the article is about how to replace the thresholds, especially since you may have them in perfect order. Someone will ask and to the threshold of the hinge with the doors? The fact is that for proper operation you need to constantly monitor how the door will fit and what the gap between the door and the threshold will be. Sagging doors can be confusing.
  2. After repairing the doors, you can remove them and start cutting out the unnecessary rotten part of the threshold. In my case, the replacement of the thresholds involves the mandatory dismantling of the wings, since at the same time I decided to replace them as well.
  3. If the car body is “decrepit” or rotten, install stretch marks in the passenger compartment.
  4. Now you need to cut off the outer part of the threshold, for this use a grinder or a file for metal, as an option a chisel is suitable.
  5. After removing the outer part, proceed with the removal of the sill amplifier (a wide metal plate with round holes around the entire perimeter).

6. In my case, there was no amplifier inside the threshold, most likely it was removed by the previous owner of my car.

  1. When all the rotten parts of the threshold are removed, it remains to remove their remnants that remain at the seams.
  2. After that, you need to properly clean the surface for subsequent welding work.
  3. Try on a new threshold amplifier, cut it if necessary.

  1. The holes drilled for welding are clearly visible in the photo.
  2. Weld the sill amplifier in place using the holes in the amplifier itself. You can make such holes using a 4-6 mm drill, approximately every 5-7 cm.
  3. For convenience, you can use clamps (clamps), with their help you can quickly and firmly fix the amplifier. Before installing the amplifier and starting welding work, you need to carefully prepare the surface of the body and any other irregularities that may interfere with a good connection.

13. Check again that the threshold is set correctly. When you decide that it is in place, start welding the threshold amplifier. Personally, I used the parallel welding method, that is, simultaneously grab both the bottom and the top, starting from the B-pillar. When the amplifier is welded, it is necessary to clean out the weld marks. You should have a perfectly smooth and even surface. Remember that the sill booster must be welded to: B-pillar, A-pillar, etc.

14.When the amplifier is welded, you need to try on the outer part of the threshold. Here, too, everything that is superfluous is cut or folded.

15. Now prepare the outside of the sill for installation. Your task is to remove transport soil, paint, etc. from the surface as thoroughly as possible.

16. Using self-tapping screws, you need to fix the outer part of the threshold. After that, you need to hang the doors and “figure out” if everything fits together. Pay attention to the gap, it should be even and the same everywhere. Also pay special attention to the gap between the threshold and the door, nothing should protrude or protrude.

17. Welding is carried out from the B-pillar. You need to slowly move in both directions, that is, boil the bottom and top, going towards the front wing, as well as the bottom and top towards the rear wing. It should be remembered that the outer part of the sill must also be welded to the B-pillar. Pay special attention to these two places, since they form the rigidity of the VAZ 2101 body.

When everything is installed and welded, proceed to cleaning the surface, then everything needs to be primed and painted.

As they say, that's all for me! Replacing the thresholds VAZ 2101 completed, if necessary, this work can be repeated in another place that needs repair.
