The gas distribution mechanism belt is one of the important parts of the SKODA Octavia A7 engine. It is responsible for the distribution and combustion of the mixture, as well as in the tact correctly distributes the injection in the combustion stone and the release of exhaust gases. If the belt does not correctly work, it may affect the stable operation of the DVS. The article will tell about the causes of the failure, consequences and the process of selecting and replacing the timing belt for Skoda Octavia A7.

The timing belt must be high-quality and durable, so it is worth it to approach his choice. In addition to the original, there are many analogues that can be put on Skoda Octavia A7. The main ones that are tested by the quality in the table below. Along the way, with the belt it is worth changing the tensioning roller because it is wearing together with the belt.

The consequences of untimely replacement and causes of failure

The late replacement of the belt and the timing roller on Skoda Octavia A7 can lead to grave consequences for the engine as a whole. Of the main expensive consequences may be repairs or a complete replacement of the head of the block.

Causes of the exit of the timing belt Skoda Octavia A7:

• stretching belt or physical wear;
• mechanical damage, or rather a gap that happens in a consequence of incorrect installation;
• bad strap stretch.

The main consequence of the late replacement of the belt will become the bent valve, which will damage the GBC. The consequences of this can become cracks in the head of the block in the landing areas of the guide sleeves of valves, saddles, as well as deformation or wear of the camshaft camshafts.

The process of replacing the timing belt

The process of replacing the timing belt Skoda Octavia A7 is simple, but will take a sufficient amount of time, because it will have to remove a lot of details, as well as set the distribution mechanism exactly with the instruction. So, proceed.

1. We dismantle the right wheel.
2. Remove the lower and top of the motor protection.
3. We merge the coolant.
   
4. We unscrew the cushion of the DVS.
   
   
5. Now you need to set VTM.
   
   
6. We dismantle the crankshaft pulley.
   
7. Remove the timing belt cover.
   
8. We dismantle the roller.
9. Remove the belt.
10. We change the belt and the video to new ones.
11. We collect everything in reverse order, without hitting the location of the crankshaft and camshaft, so as not to knock the gas distributor mechanism.

Output

Replacing the timing belt Skoda Octavia A7 is extremely important that the engine operation is correctly distributed, and there was also stability. It is worth noting that the timely and proper replacement will save the engine. Regularly it is worth checking the state of the belt and pull it up, if this is not done, it is quickly to wear and have to put a new one, and it is expensive every time.

Replacing the timing belt Skoda Octavia - the procedure, the neglect of which threatens big trouble. At first glance, nothing, for several hours, but practice shows that one incorrect movement not only negates the entire work done, but also unlocks the second world war under the hood in the Hiroshima bombing stage. Sophisticated and terrible anything ... Nothing, except for attentiveness, special tools and following the manufacturer's recommendations.

Given:

• Car: Skoda Octavia
• Year of release: 2008
• Model year: 2009
• Engine: BUD (1.4 liters, 1390 cubic meters. See, 80 hp)
• Features of DVS: four-cylinder, gasoline, simple and reliable. Book shavings, as in the beer of the same name, is missing
• Gearbox: Jhu
• Preselective PPP Robot DSG: No
• Mileage: 220,000 kilometers

Required:

• replace the timing belt

The car is served with us on an ongoing basis, we follow him and are responsible for its good technical condition. Of course, every time this car appears on our threshold, a complete comprehensive diagnosis of Skoda Octavia is performed. We look at current weaknesses, compare with the data of past diagnostics and draw conclusions, which and in what direction has changed since last visit. All malfunctions requiring eliminations are eliminated in place. If something can be postponed until the next visit, we keep this information and agree with the owner of the run or date.

Replacing the timing belt Skoda Octavia was performed preventively, in running, namely, 90,000 kilometers after replacing the previous belt.

The first thing you need to protect the workspace from the right wing, where the Skoda Octavia timing system is located - let all workers are protected by masters and do not contain sharp edges, there is always a risk to hook the wing to the instrument, so add a magnetic cape and proceed to work. The repair of Skoda Octavia, however,, like any other machine, requires compliance with not only the manufacturer's technologies, but also safety regulations. We protect yourself from the car, and the car from us.

Remove the upper engine cover, crankcase protection and lateral right plastic protection in the wheel arch to provide access to the drive system. We assign the Skoda Octavia drive belt tensioner roller clockwise, fix it with a pin and remove the belt.

Pay attention to the almost new roller belt () and smiling smugly - he was recently replaced by us. Looks like a new, pulls out well, stream belt () in excellent condition.

ELSA advises to mark the direction of movement of the drive belt, but there are two simple rules that are applicable to the timing, if you look at the installation side:

• the belt is moving clockwise;
• the belt is oriented so that the labeling is free to read (not turned upside down).

We provide yourself with the freedom of maneuver in advance, remove the top casing of the timing system, we unscrew the bayful neck of the glasswater tank and the adsorber, it is a coal filter for trapping a lot of gasoline vapor, an important element of the EVAP system.

The coolant tank can be unscrewed and removed on the hoses aside without disconnecting, but if you like freedom of action, arrow plastic clamps and remove it as the previous two positions. Again, associations with the first artificial satellite of the Earth create a good mood and a relaxed atmosphere.

Further setting the first cylinder in the NWT (the upper dead point), which combines an incision on the crankshaft pulley with the edge of the mark above it. The mark is two sheets, combined with the inner side of the right plank. For convenience, we note the control points of the special paint - it is not easier to work as an example.

On the gears of camshafts five holes: four main in increments of 90 degrees and a small retaining fifth. In our case, they did not coincide and are on different directions of the gear.

We make one more turnover of the crankshaft, again exhibit it by tags, now the lock holes stand opposite each other and lie on the same line.

For fixing camshafts, we need a special tool that excludes their offset.

The pins need not only to turn into the locking holes in the gears of camshafts, but until it stops into the fittings of the camshafts in the fittings, after which it is shifted to the bar of the pins until the engine is stopped.

Armed with a counterproof, fix the pulley of the crankshaft, turn the fastening bolt and remove the pulley. We put on an old bolt one more washer and attract the crankshaft gear, at the same time marking the paint tag and a bevelled tooth.

We post the engine using traverses, unscrew the four bolts and remove the right support of the Skoda Octavia engine ().

We unscrew the bracket with the right support of the engine from the head of the cylinder block, the bracket is located immediately under the gears of camshafts.

Weaken the tensioner of the main timing belt, turning it counterclockwise, unscrew the central locking bolt and remove the tensioner. Now it is enough to pull the pins of the retainer, remove the belt and put the retainer in place.

And here we notice that with a water pump Skoda Octavia obviously something is wrong - she had an internal limiter of the timing belt, preventing his slipping.

What can you do, you have to shoot and pump, although it has not served any signs for their replacement. As can be seen, the limiter broke out with meat and consolidate it there is no possibility. When it happened - the story is silent, but he did not have time to apply critical damage to the belt.

We put a new water pump (OEM). Its main difference in the integrated laying, while the previous one stood on a separate one.

The inner side of the main belt Timing is already beginning to rub, so the owner is lucky to come to the service. Here for comparison the surface of the new belt.

We merge the whole antifreeze in a special container. It was recently changed, so before the fill be surely filtering it.

After the cessation of the sampling, we remove the old water pump, we wash everything from dirt and antifreeze, after which they degrease the surface and put a new pump.

Now you can return to the interrupted replacement of the timing belt Skoda Octavia. Turn the roller of the connective drive belt tensioner clockwise, it is a strap of camshafts, relaxing it, then unscrew. This gives us the opportunity to painlessly remove the old belt. We begin the assembly procedure, armed with the new Remkomplekt of the timing belt ().

We check that the first cylinder is in the upper dead point, combining the bevelous tooth of the crankshaft with the label, after which they wear the connecting strap and install a new strap tensioner. We remove the fixture of the camshafts, turn the crankshaft counterclockwise to the distance of one teeth, it is about one and a half millimeters, we put on a new belt of the main drive, after which they fix the camshafts again. We establish a new Tensioner Tensioner Tensioner and a new rubber roller, after which you can remove the camshafts.

We make two full turns of the crankshaft, thereby returning the first cylinder into the upper dead point and see the coincidence in two points:

• beveled tooth on the crankshaft gear with a label on the flange sealing laying;
• the locking holes coincide with the fit, the retainer is freely installed.

If necessary, the procedure for tensioning the main timing belt is repeated, after which you can wear housings and collect the car, it's small.

It remains to install the crankshaft pulley, necessarily replacing the fastener bolt (). In the GDG sets, it does not go and is purchased separately. All planting places are cleaned, the thread is degreased, then the bolt is lubricated with oil and twists with an impressive point of 150 N · m, after which it is brought to 180 degrees.

You can, of course, to reach the eye to reach the bolt on half turns, but it is much easier to armared by a tilter, which allows you to accurately follow the manufacturer's procedure.

Everything, it remains to put the bracket of the right engine of the engine and the support itself, remove the traverse, install the drive belt, pour the lean antifreeze to wear all the removed covers and protection. Warm the engine, kicking out the air plug, and fill the antifreeze to the level. On this service Skoda Octavia can be considered made.

Complex replacement of the timing belt Skoda Octavia, taking into account the new pump, occupied 3 hours 24 minutes. The cost of all works, spare parts and consumables amounted to 16 700 rubles.

Replacing the timing belt at Octavia A7 - prices, deadlines. TO-8, pads

Machine Skoda Octavia A7, 2014 G.V., 1.4, 140 hp, Engine CHPA, DSG-7 PYU ().

Somehow "imperceptibly" mileage approached 120 thousand km. According to the regulations on a car for 120 thousand, it is necessary to produce TH-8 (TO-4). Also, 120 thousand it is recommended to replace the timing belt.

I contacted the "native" dealer to Nizhny Novgorod. The price of work on the replacement of the belt is not that embarrassing, just killed, pushing! :-).
The price of the upcoming work, on 12/15/17 \u003d belt itself (with rollers) 18,500 p. Plus 6500 p. Replacement work. TOTAL 25 TR If adding something-8 14260 r. (12834 r. With a discount of the day off), then it turns out 37834 p.
With the current state of affairs, the price is just inappropriate.

He began to "dig" the Internet. Many interesting. From "yes nafik to change it!" And "I don't need to change the belt on modern machines, because it is designed for the entire service life of the machine," to - "Actually, you need to change."
Cranks meet. Here, on DRIVE2.RU, there is an interesting information, 249 thousand km without replacing the belt!

I was aspage of the most popular service consignment. Price variable. In November of the 17th of the year 17, he voiced the price of 17900 p. For all the work on the replacement of the belt - 11400 p. The same (!) Wag-ox belt with rollers and the work is the same - 6500 p. Plus TO-8 If there is also 12 tons, totaling 29900 r. Need to minimum. It is somewhat less than in the chant, but also a lot!
Repeated bell in the conservation in December reduced the price more. The belt has already become worth a thousand 6, and then "fell", in general, thousands of 25 all works.
Anyway very expensive.

Traveled to Brother. Posted on, which somehow more is more expensive than the official dealer it turned out, etc., etc.
Began to count.
First - work. Here is a list of works on the replacement of the timing belt Octavia A7 (taken from here):

1. Remove the air filter housing and air duct
2. Unscrew and push off the expansion tank
3. Remove the top cover of gear camshafts
4. Remove the engine protection, remove the right front wheel and front right suburbs
5. Remove the drive belt with tensioner
6. Remove the crankshaft pulley
7. Remove the protective crankshaft gear cover
8. Unscrew the generator fastening bolts and push it away
9. Fix the engine special focus
10. Unscrew the engine mount bracket
11. Remove the middle metal timing cover
12. Secure specials. Device camshafts
13. Fix the position of the crankshaft
14. Remove the timing belt tensioner
15. Remove timing belt and rollers
16. Install new videos
17. Install a new timing belt
18. Fix the tensioner tightening the required torque
19. Further assembly is made in reverse order

For such "terrible", the brother requested 5 tr.

Further went the choice of materials, and for complete TO-8, including. Belt for 18,500 p. Smells immediately - well, where the fuck such prices! He contacted him in his Iksuor, where discounts have considerable. As a result, it turned out this picture:

The current picture with prices, to be honest, it turned out just a funny some kind! 7600 r. For all materials! Plus all work 5 tr. Total - 12600 p. For all that-8 and for replacing the timing belt! These are "37834 r." Three times cheaper!

Just words:
Air filter Movement: Off. Dieler - 1645 r., Real 320 p.
Oil filter: 600 p., Real 320 p.
Tube oil pallet (and gasket): 315 p., Really - they are whole and new! Do not change them every time!
Castrol EDGE 5W40 oil, 4.5 l as: 3150 r., Really Ravenol Super 5W40, 5 L, 1770 p.
Blocks brake rear: 4525 p., Real 650 p.

Well, the like and in the same style. The difference in prices for the same up to 7 times.

Why Ravenol? Yes, the fic knows! Just trust Brother. The benefit of the qualifications of it is very high (the bulkhead and cap.remont V8-X - the stage passed, already reached the Cap.
In any case, after washing the engine and fill this oil, nothing needed. I did not need something to pour (when off. Dieler Lil Castrol on that, had to pour up to 1 liter between that). And the fact that the gender was not poured into the gasoline, - did not affect anything.
And this time this specialist did not buy and did not blame.

Why does CONTITECH timing belt? Rather, why such a "terrible" price - as long as 985 rubles instead of 18,000 ??? Yes, the fic knows! Also on trust. Fortunately, the guarantee in such cases, of course, is. And not some paper yes with seals, but a real! In words, in short. According to any, if that - the engine is a bro and will redo the engine. And not for 400 thousand rubles, but "for so."
According to the "Ixorovsky" supplier - the warranty on the belt is 120 thousand km of mileage.

Rollers are also not the most "Super Vugovsky" expensive thousands of 3-4 standing, but normal, working rollers, by spent prices.

The car in the Branch garage drove in the evening to dry da fears. In the evening, I disassembled everything and all the bro.
The main work was the next day - the replacement of everything and everything. Viduha strongly disassembled cars, of course, that's more!

On the timing belt. In appearance it is difficult to say anything. Perfect reinforced rubber, all teeth in place, no even hints on cracks between ribbon and teeth. Would twist even twist! The only thing - on the outer surface - it seems and the cracks, it seems that there is no, - just such a structure of the material!

Here are these, type, microcracks .. not a special and nothing to say. Maybe the material is so. However, I would not say anything - "The belt is big wear!" Excellent belt, and theoretically there would be a hundred thousand hundred, probably ..

But on the roller yes, the video is quite worn out. In any case, the backlash is large, and he dangles on the axis (felt with his fingers). Like a poor motor worked ...
By the way, "Made in Poland" is written on the roller - this is such a "VAG".

By oil

After the previous one-7, when the same Ravenol oil was flooded (with pre-washing), then-8, after 14 t.km, the oil merged ... I would say - excellent! No black bordea! Clean, slightly dark oil, transparent on the finger. Brother, of course, and His Ohale - "It's scary dirty oil! And it is necessary to change it a maximum of 8 tons. Km! "
May be.

This time flooded the same Ravenol, 5W40, although the master insisted that it would be necessary to pour 0W30 ... The washing of the engine was also, the same washing of Gazprom-Oil MP synthetic 4 L for 330 rubles, 18 minutes at idle.
Replaced salon filter, air filter. By the way, about the air filter. About which, on the past, it was categorically said - "change at the first opportunity!". So, leaving the machine on that, suppleplate and capitally produced filter for another 14 thousand, and without any problems. The first time, perhaps, changed the air filter according to the regulations, namely, through that. And Off. Dieler forced him to change each then (well, it's clear that, if you judge at what prices they are going on), and bro.

For candles. The first, from the factory supplied, after 60 thousand looked perfectly, and the elderly master on Off. Service said - it is not necessary to change, long for a long time. But - the regulation is a regulation, they changed to new, service. And they looked, these new candles, now very much deploy! There was not enough money to new candles (even in the Ixorov prices), therefore they were put on those, the first, factory candles, 60 thousand already revealed.
At the time of writing, there are no problems with them. And they will not be foreseen, most likely (from the words of Brother, 90 t.km, factory candles work without problems).

For other results of the current garage-8: Brake pads are filled! Change urgently! And on the "DR-DR" in a bad road - "The front racks of stabilizers is time to change!"

They ordered them immediately, in the same Ixore:

Well, prices, of course, again, are simply unreal!
After a couple of days, spare parts came, and again in the garage. For work in this case, however, I had to "overpay". At first, it was voiced - "1000 r. In a circle I take over the replacement of the brake pads. " Well, plus 200 - replacement of stabilizer racks. However, the price of grew up. Because 120 thousand km is a lot. And the brake pads wear out quite strongly (he himself changed both in front of the age of 60). Therefore, the pistons were nominated a lot, which led to their overheating and some deformation. To eliminate which it took very strong efforts, well, the expressions appropriate! :-).
Plus the racks of stabilizers who have changed the first time, their fastenings, whining to death, had to even cut the nuts with a grinder.

Therefore, 1,700 r. TOTAL 5 TR For the replacement of all pads and front racks of stabilizers.

The week of operation after TO-8, the replacement of timing, pads and stabilizers:

1. DR-DR-DR on bad roads left. No, at all off-road any car will rattle, probably. On less normal roads now silence in the car!
2. New brakes "rolled out" for a long time - kilometers 300 it took the "vitality" in the brake pedal (the effect - as if not the pumped brakes), and the brakes "earned" in full.
3. At the first refueling after replacing the timing, the consumption seems to be rose, and quite strongly (with 8 to 9 liters (city, traffic jams, snow-water-mud slush)). Judging by the Internet - a normal phenomenon and soon the flow must come to normal.

Total Total - the car whispers and everything is super! For everything about everything came out 17600 p. (TO-8, TRM, pads, racks).

For the future.
Brake discs drove strongly. Therefore, thousands of 30, to 150 bend - cook money on their replacement (somewhat deplorable - when replacing discs, all pads must be put new!).
Oil change through the next 8 t.km! With mandatory flushing. And then also. This is then 300 taxes of trouble-free run - by no means the limit.

The total summary of this post: no way to relax in our troubled time. And nothing can be bought immediately and how I liked it! Any purchase of goods, work, services should always be preceded by very painstaking work on the search for the most profitable options. Therefore, the difference in the prices of the current ones absolutely the same can be tens of times.

Good luck on the roads!
