Advantages And Disadvantages Of Forged Wheels The most popular discs for vehicles today are light-alloy wheels of metals. They are divided into two types - a light alloy wheels and forged. Alloy wheels are usually made of magnesium alloys and aluminum. Forged in Essentially, all made from the same materials, but a very different way. Forged wheels are produced by hot pressing, and then go through the process of artificial aging and hardening. Worldwide, it is considered that Forged wheels - an advantage wealthy car owners. And this is true, but in Russia there are several companies who have inherited the expensive equipment from the Soviet era, and yet they can afford production of relatively cheap forged wheels, which differ in price from western counterparts in several times. Because of technology, these discs is a little lighter than the cast, but they are much stronger, less brittle and quite suitable for repair. In the bumps, these discs do not break or crack and warp. But it is precisely this strength and is a minus forged wheels. (A valuable related resource: Tony Parker). For example, hitting the hole, the drive will not blow over, and pass it suspension, is clearly not designed for such loads. Designs and different shapes that appear when you select cast wheels, forged wheels have not found. This is due to the fact that the manufacture of molds for them are extremely expensive. In general, the forged wheels is the best option, which combines the advantages of steel and alloy wheels. But just such an important consumer characteristics such as price, makes for many, this drive is extremely expensive pleasure, because it exceeds the price of light alloy wheels in a few times. Also, it is sometimes difficult to distinguish yourself from forging casting. There are only a few indirect signs. Of course,...

Adjustments Remove the protective cover of the belt drive. Install the camshaft in the direction of rotation in the upper dead point and align the mark on the engine and the camshaft. Loosen the screw tensioner. Move the clip to the end position of the belt and tighten the screw. Remove the timing belt. Check the condition of the surface of the belt on absence of mechanical damage on the part of the drive components and surfaces themselves parts - gear, roller guides, etc. Check the runout of bearings. If necessary, replace the parts. Set all labels to the corresponding provisions of the TDC. Install new belt on the toothed wheel and drive components. Loosen tensioner pulley bolt, so that he freely moved in the direction of the belt. Set the video to the end position, observing the proper belt tension. In systems without automatic tensioning roller use measuring devices for checking belt tension. Check the position of labels. Crank the engine in the direction of rotation for at least 2 full turns to ensure optimal tension belt. Recheck the position of labels. Tighten the clip to the prescribed torque. Install the cover and all you have taken part in its place. Install the cable 'weight' on the battery. Start engine. If necessary, conduct the necessary adjustments Adjustments timing or injection. Dispose of the old belt. Some of the comments when mounting, if required maintenance manual, use special tool. Lay the belt by hand, avoid the use of screwdrivers and other tools that can damage the surface of parts or belt drive, especially its lateral surface! Do not use cleaning chemicals can damage articles made of artificial materials. Do not let the appearance of a protective casing of oil mist, oil leakage from associated knots! Always follow the instructions maintenance manuals...
