Advice 1: How to adjust the tension

The correct adjustment of belt tension of the generator depend on the terms of service: batteries, bearings of the generator and the water pump and alternator belt. Loosened the belt starts to slip on the pulleys, which leads to intensive wear, and the generator in such circumstances is unable to provide energy sufficient to fully charge the battery.Excessive tension of the belt creates an increased load on bearings of the generator and water pump, which contributes to their accelerated wear and failure. In addition, when such tension in the belt begin to tear filament cord and can end at any moment, having served a very short period of time.
How to adjust the tension
You will need
  • spanner 13 mm,
  • - wrench 17 mm
  • - mount,
  • - the range.
To verify correct belt tension, you need to put over the pulley on the alternator and water pump any flat, metal object such as a narrow mount. Then you want to press your hand down on the center of the belt, then measure with a ruler deflection, which is when the force equal to 3-4 kg, should not SAG more than one inch. If the test measurement does not correspond to the norm, it is necessary to adjust belt tension of alternator drive belt.
To solve the problem is the loose nut of fastening of the generator to a tension lath and bolt the lower mount to the engine bracket.
Then pry the alternator away from the engine, and in this position is fixed by tightening the nuts on the tensioning strap. Then check the degree of belt tension.
If the tension meets the technical requirements, then the final tightening of the upper and lower mounting of the alternator on the engine.
In cases where the tension of the timing belt didn't execute properly, then mandatory to repeat the process.
The correct tension of the belt drive generator and water pump ensure a comfortable operation of the vehicle over a long period of time.

Advice 2 : How to set a sewing machine

If you bought a new sewing machine, and she is not working as you would like, it's not a reason to carry it in repair or to return to the store. It can be just not configured. This means that we need a machine to configure, before you begin work.
The ability to customize a sewing machine will save you from many problems
A spring, which shakes the thread, should be rigged below the cap, filled with a spool and located in a raised elongated end of the thread state, did not give the thread to spin until we pull her up sharply.
The upper thread is passed through the feed system. This process usually looks like this: the thread that runs through several metal tabs, then passes through the Adjuster, then it is skipped in the ear notarialnogo lever and a few staples it gets in the eye of a needle.
How to skip the thread, we understand. Now on to setting up the tension. The most beautiful and high-quality stitching we would get if the bottom and top strands are intertwined in the depth of the material is invisible to the eye. It happens, if the thread tension is correct. The tension of the upper thread, we can set up a mechanism on the front of the machine, and the lower the adjustment screw, located on the Shuttle.
Setting the tension of the lower thread to hold easily, so we will not consider this case. And we will address better the process of setting up the tension of the upper thread, which consists in twisting a screw, which compresses the saucer washers. So, to test take a small piece of tissue and prosem it. If the hinges are hanging out, means that the upper thread is too loose or too much tight. If the seam is relatively flat, then the look – which side is stronger visible nodules plexus of the lower and upper thread. Nodules are usually easily palpated by the finger. If the tension is set correctly, the nodules are no longer palpable.
So, the conclusion:
The nodules are approximately in the middle of the seam and not be felt (not palpable). This suggests that the tension of yarns optimally.
Nodules grope on the bottom side. This means that the upper thread is tight enough.
Nodules grope on the top side of the seam. In this case, the needle thread tension is above normal.
Hanging loop work – the needle thread tension deviates strongly from the norm, in one direction or the other.
The seam will be weak and unusable, if the lower thread bobbin loosely placed on the cap or not tight. The top thread also has a weak tension.
Setting the pressure foot can be done by means of a spring. Automatically this setting is in the most advanced models of sewing machines. Enough for sewing thick materials provides for the presser foot lift to a height of 12 mm. If the foot pressure on the material, it may cause displacement linked layers, difficulties, and sometimes and tear of the fabric. If the presser foot on the material is almost no pressure, get the wrong seam.
