One of the most critical mechanisms in any car is gas distribution. The quality of the engine in different load conditions depends on its condition and serviceability. Previously, a chain drive was used in the design of this system. Recently, however, manufacturers are increasingly using a belt drive. The Hyundai Accent was no exception. Timing Belt Replacement is a procedure that everyone should be aware of.
Characteristic
What is this part? This is the element that drives the camshaft. In the engine of Hyundai Accent cars there are 1 or 2. They are rotated by transferring forces from the crankshaft pulley.
Thus, the higher its speed, the more often the camshafts rotate. The system is quite complex and includes certain tags. Their mismatch can lead to serious engine repairs.
About Resource
How often should the timing belt be replaced by a Hyundai Accent? The manufacturer notes that this element has a resource of 60-80 thousand. But it is worth noting that the element can wear out even earlier than the stated time period (for example, with improper tightening). Therefore, you should know the symptoms of this element.
Symptoms
It is impossible to determine whether the timing belt needs to be replaced with a Hyundai Accent by the nature of the movement. The only verification method is a visual inspection. To do this, open the hood and remove the plastic protective cover with a spanner. First of all, pay attention to the condition of the teeth from the inside. They should not be pulled out of the seats.
It is also not allowed to have cracks on the belt (both from the outside and from the inside). Another sign talking about replacing a belt is its delamination. For greater strength, threads are used in the construction. If they crawled out, this is a bad sign. Such an element is no longer subject to further exploitation.
Getting to work. Belt removal
So, first you need to jack the front left part and remove the wheel. Next, open the hood and loosen the pump pump pulley bolts. All you need to unscrew the four bolts. Next, remove the belt from the air conditioner (if one was installed on the car). To loosen the belt, slightly unscrew the tension roller. Next, we need to remove the generator belt. For this we need heads "12". In addition, we unscrew the power steering shaft. The amplifier itself can also be removed.
We remove the pump pulley with a belt and disconnect the GUR tank fixture. The latter is slightly shifted to the side. Next, remove the side engine mount (the one that is attached to the right wing). In the direction of the work, we examine its condition. The engine mount must not be cracked or play. Otherwise, we change it to a new one.
Then we unscrew the plastic casing under which the timing belt is hidden. Using a ratchet and a “22” head, we unscrew the bolt located in the middle of the crankshaft. Be careful - it is twisted with great effort.
If you can’t unscrew it by hand, turn the starter (shift the gearshift lever to “neutral”). We shift the timing belt tensioner pulley towards the pump and fix it in this position. We unscrew the camshaft pulley bolt and remove the pulley itself. How is the timing belt replaced with a Hyundai Accent? After that, you need to loosen the bolts of the old roller. The latter must be held so as not to lick the threads on the spring.
Belt replacement
Now you can safely remove the old element out. How is the timing belt replaced at Hyundai Accent? A complete guide will be described below. After dismantling the worn drive, we replace the tension and bypass roller. They change in case of whistling or other noise during rotation. Usually they have the same resource as the belt. Next, put in place the crankshaft pulley. It is better to install it with a torque wrench. The tightening torque of this bolt is from 90 to 120 Nm. You will have to make every effort to twist it. Never use an open-end wrench. So you can lick all faces. The crankshaft bolt is twisted only by a hex head.
How is the timing belt replaced on the Hyundai Accent? Then the guide roller is installed . It is tightened with a “18” key with a force of 43-50 Nm. After that, you need to combine the labels that are on the camshaft and crankshaft. In this case, the piston of the first cylinder should be at top dead center. How to determine this? It is enough to remove the candle and put in its place a screwdriver with a long "sting". Further, gradually turning the pulley bolt, monitor its position. As soon as its tip reaches the upper position, this will be the top TDC of the cylinder.
Then we establish the tension mechanism, namely:
- Tension roller.
- Spacer sleeve.
- To the spring.
We install a bolt (or awl) in the elongated hole and “cock” the roller. After installing the belt, pull out the bolt. A distinct click will be heard. Thus, the belt will automatically tighten. Once again we check the coincidence of all labels. By the way, they are duplicated on the plastic belt cover.
Assembly
At the next stage, tighten the roller adjusting screw and rotate the crankshaft two turns clockwise. If the marks do not go astray, then at the Hyundai Accent the timing belt replacement was successful. By the way, you can rotate it not by a starter, but manually, while engaging in fifth or fourth gear.
Then install the engine mount, pump pulley and plastic casing. Do not forget about the attachments - power steering, alternator belt and air conditioning. After that, we conduct a test run. The machine must not troit or make extraneous noise.
Recommendations
When replacing, it is worth highlighting a couple of boxes or containers for bolts.
It is advisable to sign them, so as not to get confused when installing them. We hold the bolts with a torque wrench and avoid using open-end wrenches.
Conclusion
So, we found out how to replace the timing belt on the Hyundai Accent. The cost of such work at the service station starts from two and a half thousand rubles, not counting the price of the belt and roller itself (and this is also a plus one and a half to two thousand). In time, this operation will take you about two hours.
