Advice 1: How to adjust valve on the GAS 31029

Improper adjustment of valves on the "Volga" GAS-31029 entails a number of consequences. Among them is an unstable work of engine failures during acceleration, hard starting and other. The adjustment of the valves conduct in the same manner in which the work cylinders, that is 1-2-4-3.
How to adjust valve on the GAS 31029
You will need
  • - crank (curve starter);
  • - metal brush;
  • - the wrench;
  • - feeler gauge blade.
Instruction
1
Before the adjustment, wait until the motor cools. Open the hood, find the distributor (breaker-allocator) and remove the cover. To find the distributor wire going to the spark plug of the first cylinder. The first cylinder is the one closest to the radiator. Visually note the position of the runner rail, in which power is supplied to the candle of the first cylinder. When viewed from above this situation will be "ten hours."
2
Remove the valve cover, incidentally removing all attachments located on it. Inspect the crankshaft pulley, and locate it 2 or 3 installation risks. Often they are hidden under a layer of dirt and rust, so clean the pulleys with a wire brush. Rotating hand-crank the crankshaft clockwise, align the last mark with a label the pins on the cylinder block. Note that while cranking the engine behind the belts and pulleys you can knock the ignition control.
3
If after following the previous steps runner distributor is visually noted previously place, then the piston of the first cylinder came up to TDC position. Valve must be closed and can be adjusted. Try to wiggle the rocker arm of the valves – they should have a small gap. If the runner dispenser was at a different point, you can begin the adjustment valve of the 4th cylinder in the order 4-3-1-2. Make sure that the valve of the 4th cylinder closed shake of their yoke.
4
With a feeler gauge measure the clearance. To do this, pick a probe that would enter into it with minor, but tangible force. The required clearance value is 0.35 mm. For its correction it is necessary to loosen the lock nut of the adjusting bolt and rotate the bolt to set the desired value. Tighten the nut in stages, constantly monitoring the size of the gap with a feeler gauge. This is necessary due to the fact that when tightening this nut, the gap tends to decrease.
5
Using described algorithm of actions, install a thermal gap on all cylinders. The required gaps – 0,30-0,35 for the second and third cylinders, and 0.35-0.40 for the first and fourth cylinders. If the ambient air temperature at the time of adjustment of the clearances is +5 degrees and below, set the gap at 0.05 mm above the desired value. Remember that adjusting one cylinder, rotate the crank a crankshaft of the engine 180 degrees. At the end refit the distributor cap, start the engine and verify that it works.

Advice 10: How to adjust sink bowl

The drain of the toilet must function properly, otherwise the use of the device becomes difficult. A similar problem can often be eliminated fairly quickly on their own.
How to adjust sink bowl
You will need
  • Toilet cistern, valves, requiring replacement.
Instruction
1
Define the exact purpose of the adjustment of the drain of the toilet. What you want to achieve: reduce the amount of flushing water or, conversely, to increase it, or need to adjust the constant drip of water?
2
Change in the amount of water drained from the reservoir. Open the lid of the toilet tank. Adjust the float so that it overlaps the inlet when the water reaches the desired level.
3
If the water from the tank flows continuously install the problem. Look under the toilet tank lid and verify that float and drain valve are straight, have no bias. If necessary, correct their position, and the drain will be adjusted.
4
If that doesn't work, find where the cause of the water leak. In modern cisterns the water often flows through the overflow tube. Change the angle or height of the float by bending the yoke so that the water level in the reservoir was slightly below the top edge of the overflow pipe.
5
Check the inlet valve. Lift the float up until it stops. Valve connected with the float by means of the rocker should shut off the inlet valve fully. If water continues to leak, replace the faulty inlet valve with a new one.
6
Turn off the water. Unscrew the Union nut of the water fittings to the reservoir and the nut of the valve. Remove the valve. Then install the new in reverse order. Turn on the water, check the inlet valve.
7
If the tank is old design, he may stop to keep water drain valve. Tweak its position or adjust the fit of the "pear". Turn counterclockwise the plastic threaded fasteners drain button valve tightly blocked drain.
