Changing the timing belt car Toyota 1G
The reasons for the timing belt wear (RM) may be different, but the two main - the age of the vehicle and the quantity of run. The more mileage, the more reasons to replace the timing belt. Series engines 1G Toyota cars are good because when you open the hood all the units of this engine are viewed very well, which greatly facilitates the work and it takes a little work time. Before replacing the timing belt wait for the engine to cool down, because the engine heat will not be able to achieve the desired belt tension. In the early work necessary to remove the air filter, resonator and tube cooling system. Then be sure to disconnect the battery, remove the hose leading to the radiator, the rim of the fan, V-shaped straps, disconnect which requires special care, and the actual radiator fan. Candles are not necessarily to shoot, but experts recommend to do this is to avoid high compression engine at the first scroll down after installing a new belt. Before removing the shrouds that cover the timing belt, you need to remove the crankshaft pulley, for this purpose need a special puller to remove the pulley. Keyway crankshaft at the same time must coincide with the keyway pulley. Sam crankshaft to rotate clockwise. Crankshaft can be rotated only when wearing a belt to avoid being struck on the valve piston. Please note that on the back of each gear has a label, which coincides with the tide on the motor housing. It is here that need to start shooting belt, loosening the guide and tension rollers. Do not forget to check whether the timing belt on oil, if the belt is dirty, you need to figure out where the leak. Once you have removed the belt, guide and tensioner need to set in place. In this case, a guide roller fastens you completely, but the tension - a little, but so that he hung around. You are now ready to tension the new belt. New timing belt put on in the following sequence: first, to the crankshaft, then the oil pump, guide rollers, pulleys camshaft, and only then on the tension wheel. In this movie needs a little weakened, he will shift to the right by a spring and a belt natyanetsya. Specifically draw roller is not needed. Once the timing belt to tighten, the crankshaft 2 - 3 times strictly in a clockwise direction. It should be done cautiously, slowly. Cranking the crankshaft counterclockwise will cause that the timing belt natyanetsya wrong that can lead to inoperable motor. After that, carefully check the labels on the gears. If the tags are identical with the tides on the body of the engine, turn the crank a few more times. Otherwise will have to start pulling the timing belt again. Once you've verified that the belt is tensioned correctly and all tags are identical, you can start the engine. Without those parts that you removed from the start, the engine can operate safely for about three minutes. Before you start the engine, make sure the transmission is in neutral. If the engine fails to start, as usual, this means that the timing belt tensioned correctly, and can be set in place all removed at the beginning of the parts in reverse order. The engine is ready for the next 100,000 miles. run. And another tip. When you come to the conclusion that you need to replace the timing belt, do not skimp and buy the original (look at the label of your belt). Forgery can do a lot more expensive than buying the original belt. The original belt can also replace its analogs, but in this case, you need to look at the size of the tooth belt. In some cases, the size can not match.
