Timing chain SsangYong New Action is literally a chain designed for correct timing, timely opening and closing of valves. The pulley is equipped with marks that allow you to rationally set the position crankshaft in relation to the distributive. Used SsangYong New Actyon timing chain on gasoline and diesel engines... Tearing it is quite difficult, unlike a belt. But in the process of wear, it can stretch a few centimeters. From smooth operation the chain completely depends on the entire operation of the engine, it is worth carefully monitoring the mechanism and replacing it in time when it is worn out.
Most frequent problem is the stretching of the chain, which leads to its jumping by several links and breakage. In the event of a break, the pistons meet with the valve, which threatens overhaul engine.
Timing chain SsangYong New Actyon g20d (gasoline) - mechanism advantages
The main advantages that can be attributed to the SsangYong New Actyon g20d timing chain (gasoline):
- the mechanism has the highest resource;
- has a high resistance to external factors. She is not afraid of water, dust, dirt, various temperature changes;
- the timing chain can be installed with precision in each mark, respectively, independently adjusted, which means it can be fine-tuned, which contributes to more rational control of the intake and exhaust valves. Even if it is already stretched, the valves do not burn out and do not coke, which is very important;
- significantly increases the resource of the chain by the fact that it is constantly in oil;
- if there is a place for a workable SsangYong New Actyon chain tensioner, then it will not jump forward on the tooth, no matter what mode you have to work in. The timing chain is highly resistant to heavy loads and is able to withstand the highest rpm;
- durability. The timing chain is capable of serving 300-500 thousand km without the implementation of any kind renovation works... Of course, it is necessary to visually view the mechanism in order to identify deviations in work in time.
Talking about flaws chain mechanism, it is worth mentioning its noise level, which is several times higher than that of a belt drive. The downside is the complexity and high cost of replacing the SsangYong New Actyon chain. When replacing, you will need to purchase a set of spare parts with various sprockets, tensioners and straps. It would be more rational to contact a specialized salon and replace the chain mechanism there. Experienced specialists will do the job faster and better. The independent performance of this manipulation does not guarantee the further quality of work of the already new mechanism. If the chain is improperly laid and aligned, it will quickly fail, which can lead to even more adverse problems.
Replacing the timing chain with a SsangYong New Actyon is a painstaking and time-consuming job, not every experienced car owner can do. If you are not confident in your abilities, it is better to contact the service station and trust the professionals.
This article will focus on the timing chain, abbreviated timing.
Timing chain functions
Timing chain on SsangYong Actyon connects the crankshaft and camshaft (s) to each other, and also ensures synchronization of their rotation. The functionality of the timing chain is no different from the belt, ensuring that the timing chain works like gears on a bicycle.

Timing chain myths
There is an opinion that if your engine does not have a belt (timing), but a chain, then you do not need to worry at all - this is a steel chain, after all! The chain, without any doubt, is much more resistant to external factors (water, oil, dust) than a belt, but it is not at all eternal - it wears out like any part of your car. Only the chain, in contrast to the belt, does not have a replacement regulation, that is, you have to navigate "by feeling". For example, on a SsangYong Actyon car, the timing chain is a real headache! After all, already at 30 thousand mileage, it can fail!
How can you tell if a chain has reached its last kilometers?
We have already figured out that the chain does not possess immortality, so how does it “die”? Let's look at the example of SsangYong Actyon, since this problem is most common here. In the process of operation, the chain wears out - it stretches and begins to emit a "clang". Important! The chain always makes noise during operation, but due to modern soundproofing, you most likely did not notice it, if you have doubts about strange sounds in the engine area, it is better to contact a car service. If your chain on the SsangYong Actyon is stretched (it is also important for other cars), at first it will emit a "clang" when starting "on a cold", and when the situation worsens, it will publish it constantly. In a completely neglected situation, the chain may "jump", and then your car will stall and will not start without replacing the chain.
This is what a stretched chain looks like. It becomes completely "wooden".

What is the threat of a timing chain malfunction?
Unfortunately, noise from under the hood is not all that threatens you and your car. Above, we described the chain jump option, due to which the car stalls "tightly". This course of events is much more dangerous than it might seem, imagine that you will stall not in a parking lot, but on a busy highway, the picture has changed immediately, right? In fact, it's even worse, because when the engine stops working, the following happens:
- Brakes fail. When the engine stalls, it stops working vacuum amplifier brakes. Some will say that our fathers and grandfathers drove cars without any amplifiers, and there were brakes. That's right, but the brakes were not designed with an amplifier in mind, that is, they were designed for human strength. Those who have modern car deaf on the go, they will say that it feels like there are no brakes at all.
- The steering wheel wedges. When the engine stalls, the power steering stops working. In reality, the steering wheel does not wedge, but the sensations are exactly the same, since it takes a lot of effort to make the car turn. Electric power-assisted car owners can relax, they are not affected.
Thus, a chain jump can send your vehicle to body repair, and you in intensive care. So no matter what you have: a chain or a belt, both of them need regular monitoring and timely replacement.
On some cars, when the chain jumps, the pistons bend or even break the valves. Fortunately, this does not apply to the SsangYong Actyon, as we have not seen a single car with bent valves... But damaged camshaft gears are periodically encountered, and taking into account the fact that one of them is with a phase shifter, this further increases the already not small cost of repairs.
What to do to avoid problems with the timing chain?
Unfortunately, there is no good solution at the moment. There is no way to avoid the problem. It remains to closely monitor the state of the chain and change it when stretched.
There is very little space in the car for repairs, which is not at all a plus and greatly complicates the repair, and also prolongs it. Usually, replacing a chain with an SsangYong Actyon takes about a day and is quite expensive, due to the fact that, firstly, there are no good analogs chains, and the original, to be honest, leaves much to be desired, and secondly, for reasons associated with the complexity of this process. And we leave all the "Kulibin" repair methods to the "Kulibins" at their own risk.
Today we'll talk about how to replace the timing chain in Ssangyong Actyon cars with our own hands. I think all owners of the SsangYong Aktion are aware of the chain jump problem due to its stretching. You can perform self-diagnosis by removing the valve cover and assessing the condition of the circuit.
How much does the timing chain and its replacement cost?
The original timing chain with the number 1729970094 (for gasoline) costs around 12 thousand rubles, by the way it is made in China. Calling official dealers it was found that the procedure for replacing it ranges from 17 to 30 thousand rubles. It turns out not the most cheap repair if you trust professional craftsmen. But you can save a lot. Lots of Ssangyong owners Actyon supplied themselves with a chain from UAZ produced by Czech CZ. Its reliability has been tested, even put on a Hummer. One chain for 84 links costs an average of 800 rubles, you need to buy two sets and make 146 links from them as in the original.

You can order from ALI Express or make chains for a bicycle out of squeeze.
Video of replacing the timing chain in Ssangyong Actyon using G20D tags:
For the convenience of viewing, we recommend expanding the video in full screen. On this car, the chain has recently been replaced, but the camshafts were incorrectly installed, there was a lag of one tooth. At the same time, the Chek Engine did not burn on the panel, but there was a weak acceleration, the power was lost. After setting the labels, the problem disappeared. The author of the video does not comment on the progress of the work, but text annotations are inserted in the video, which explain incomprehensible points.
