How to remove a VAZ 2107 axle shaft, replacing the oil seal, size, drawing, instructions with photos and videos

An oil seal is a special seal in a vehicle that is necessary to seal gaps and cracks. For example, in a gearbox, the oil seal plays a vital role - it is fixed at the junction between the moving and stationary mechanisms, preventing oil from leaking out of the gearbox.

The oil seals in the VAZ 2107 gearbox are not made of rubber, as most drivers believe. In fact, this product is constantly in the transmission oil, and to keep production to a minimum, manufacturers make oil seals from CSP and NBR composite materials. At the same time, the gasket feels equally “good” at any temperature - from -45 to +130 degrees Celsius.

Box seal dimensions

The gearbox itself on the “seven” is designed for many years of service. However, the service life of the device directly depends on how often (and in a timely manner) the driver changes the seals. Indeed, during the operation of the machine, it is the oil seals and sealing joints that are the first to fail (tear, wear out, squeeze out). Therefore, timely replacement of the oil seal will help prevent expensive repairs of other gearbox mechanisms.

For proper replacement, you need to know the dimensions of the VAZ 2107 gearbox seals:

1. The input shaft seals have a weight of 0.020 kg and dimensions of 28.0x47.0x8.0 mm.
2. The secondary shaft seals weigh a little more - 0.028 kg and have the following dimensions - 55x55x10 mm.

Which ones are better

The main question for any VAZ 2107 driver when repairing the gearbox is: which oil seal is best to put on the shafts to avoid rapid wear? In fact, there is no universal option.

The standard equipment of the shafts involves the use of Vologda oil seals, but if necessary, you can install any others, even imported ones.

Industry leaders can be considered:

• OJSC "BalakovoRezinoTekhnika" (main materials of manufacture - composites and alloys);
• (the main manufacturing material is thermoplastic elastomers);
• (made from rubber compounds with various additives).

The most affordable oil seal for a box shaft costs 90 rubles; the more modern the manufacturing technology, the more expensive the product will be valued.

VAZ 2107 driveshaft design

The VAZ 2107 driveshaft consists of a pair of main parts connected by a jumper. Attached to the front of the driveshaft is an elastic rubber coupling that connects the driveshaft to the gearbox. The rubber coupling provides shock absorption, and the slotted connection allows the driveshaft to move back and forth when the angle of its parts changes or vibrations of the engine and transmission when driving over bumps and potholes.

The main parts of the gimbal are made of hollow tubes, which minimizes its weight. Reduced mass (hence inertia) reduces the load on the engine and transmission parts of the vehicle.

To avoid vibration when the cardan rotates, its parts are balanced at the factory using special equipment. To ensure balance, apply the required weight to the outer surface of the gimbal.

Why are they installed in engines?

All rubbing couples in engines receive a certain portion of lubricant to reduce friction, and the task of oil seals is to reduce its entry into the combustion chamber to a minimum. Such a pair in the cylinder head is the guide sleeve and the valve stem. It is impossible to make this connection without a gap, so valve seals are used for sealing. They are made from special oil-resistant reinforced rubber. The upper part of these seals is pressed against the valve stem by a spring.

There was a time when PTFE was widely used for these, but nowadays it is rarely used in the production of these replacement parts. Instructions for car repair and operation recommend that when replacing, install only those parts that were installed by the manufacturer. Today, this recommendation is often violated, since the use of high-quality materials and modern technologies makes it possible to create products that are in no way inferior, and sometimes even superior in their characteristics, to the original caps.

Replacing the gearbox input shaft oil seal

The gearbox input shaft oil seal is in contact with the clutch housing. If it is necessary to replace it, the casing must be dismantled. Especially for this you need to arm yourself with wrench heads, a screwdriver, a puller, or you can use a knife. If you need to replace the gearbox output shaft oil seal, you need the same tools, plus the pliers that are needed to grab the old oil seal.

Replacement is carried out in a number of stages:

1. Disconnecting the gear shift fork.
2. The bearing is removed.
3. The casing is removed.
4. The oil seal is removed from the input shaft.
5. The oil seal seat area is cleaned.
6. A new oil seal is installed.
7. All dismantled components of the box are assembled in reverse order.

Taking this into account, there are no difficulties in carrying out this procedure.

The dimensions of the VAZ 2107 gearbox oil seal (input shaft) are as follows: 28×47×8 mm. Secondary shaft oil seal size: 55×55×10 mm.

Thus, timely replacement of oil seals helps prevent costly repairs of manual transmissions. It is important to purchase these items with the appropriate characteristics.

Signs of a malfunction of the input shaft bearing of the VAZ 2107 gearbox

There are several signs that indicate a bearing is faulty:

• When the engine is running at neutral speed, extraneous noise is heard, which changes with increasing speed.
• The gearbox periodically taps while the car is moving. And the knock is present in any gear.
• Gears switch on or off spontaneously.
• The clutch does not engage due to a stuck bearing.

The problem cannot be ignored: misalignment of a faulty bearing will lead to breakage of the clutch basket. Replacement of the secondary shaft oil seal for gearbox 2101-07. -. And even if misalignment does not occur, a worn part will cause rapid failure of the gearbox and/or clutch.

Bearing replacement can only be done on a removed gearbox. This is where the work begins.

About the reasons for replacement

There are many reasons for such a replacement; let's look at some of them. An example is the cost of “native” products; the price of individual copies can range from $5 per piece or more. There are also situations when one of the oil seals may be damaged during assembly, and you need to look for a replacement. This is where knowledge of the characteristics of manufactured spare parts can come to the rescue in order to select a replacement.

We can talk for a long time about the advantages and disadvantages of such products of domestic and imported production. We tried to tell you which valve stem seals are better in accessible words. In conclusion, I would like to note that, unfortunately, the quality of domestic products is still inferior to foreign caps.

Actually the subject is the size of the valve stem seals felicia, 1.3l engine. 58 horses, last time I changed the caps, I bought an analogue from the original number, in the end the size of the caps I bought turned out to be 8 mm by 10.8 mm, of course, now they are lying idle, thank God, after shopping around in the existential store, suitable caps were found, but they Unfortunately I don’t remember the size, it seems to be 7mm by 10mm, if anyone can tell me the exact dimensions I would be grateful... or the size of the caps from the 16-valve ten seems to be identical

Changing the oil in the rear axle of a VAZ 2106

Often, car enthusiasts who own a vehicle such as the VAZ 2106 ask the same question. They are interested in which oil fluid is best suited for the rear axle of their car. At the same time, they ask - what volume is needed and how to change the oil?

There are different opinions. But experts recommend filling the rear axle gearboxes of this machine with transmission oil, which is marked 80W90. For example, this is Lukoil 80W90 GL. This group of oils also includes TAD-17 80W-90 or the so-called TNK.

When we've sorted out the oil, it's time to answer another question. Perhaps he is one of the most important. Namely, how much oil is required? So, the oil volume is as follows - 1.3 liters. At the same time, it is possible to change the oil in the gearbox. True, in this case you will need 1.4 liters.

As for the interval, it is necessary to change the oil fluid after every 30,000 kilometers of the vehicle. If you convert the mileage into a time frame, you get 3 years of operation.

The oil fluid is replaced in accordance with the established procedure:

1. First of all, you need to use a lift or inspection hole. You will also need a key for “seventeen” and a hexagon for “twelve”.
2. Next, unscrew the drain plug in the bridge and place a special container designed for draining the oil fluid. At the same time, the filler plug is also unscrewed. This is necessary so that the oil fluid flows out faster.

We unscrew the drain and filler bolts. When the oil fluid is drained from the bridge, the drain plug is screwed in and new oil is poured. Here you need to use the filler hole. You will also need a special syringe or other suitable tool.

Therefore, it is better not to try to tear the grenade out of the box by pulling the brake disc, but to insert a prybar under the grenade and a tube under the prybar, try to squeeze the grenade out of the box if it was squeezed out perfectly. It happens that a grenade cannot be squeezed out, then it is knocked down with hammer blows.

Photo. Removed grenade from the gearbox.

But before squeezing out the grenade, place a container to collect the oil; it can be made from an old canister by cutting a hole. If the oil in the box is normal, then it will definitely flow out of the box.

How to make a replacement?

To start work, you should send the VAZ-2107 to the pit (otherwise you won’t be able to get to the parts). After this, you need to set the first gear to fix the crankshaft. Attention! The machine must be well secured with the parking brake. To replace the front crankshaft oil seal you will need:

1. Disconnect the protective shield. A key set to “8” is suitable for this. If an injection model is being serviced, it is possible to install an additional shield; it will also have to be dismantled.
2. Remove the alternator belt. To do this, unscrew the generator nut and move it all the way to the side.
3. Using a “38” open-end wrench, unscrew the nut securing the pulley to the crankshaft and remove it.
4. Remove the oil seal from its seat. To do this you will need a wide screwdriver. After this, the box needs to be thoroughly wiped with gasoline and the new cuff lubricated.

Then everything is assembled in reverse order. The outer diameter of the oil seal is 4 mm, the outer diameter is 56 mm.

How to choose the best?

Almost until the mid-90s, domestic cars were equipped with products from the Kursk Rubber Products Plant. The average temperature in the working area is approximately 1800°C, and the rubber used to make them was only rated up to 1500°C. Therefore, the mileage of such parts was no more than 30 thousand km. mileage Today they are not produced, but occasionally they still appear on sale.

With the arrival of technologies from Porsche in the domestic auto industry, the production of caps based on a new composition began to develop. It was based on fluorine rubber, the use of which gave positive results. After comparative tests with products from such and Elring

"Good results were obtained.

For an unworn pair of valve stem and guide sleeve, caps perform well. They are based on high-quality rubber; they successfully replace Mercedes M110 and M123

fluoroplastic products.
In addition to the names listed, products from Glazer
and other companies have proven themselves well.

Instructions

1. Place the car on a lift.
2. Disconnect the wire from the terminal.
3. Remove the flywheel.
4. Remove the rear shield of the clutch housing, which is directed towards the bushings.
5. Unscrew the bolts (8 pieces).
6. Remove the holder from the part.
7. Now you need to knock it out of the gearbox; to do this, use a screw and a hammer.
8. Now we take the new element and press it into the holder. Outer diameter - (99±0.5) mm.
9. The working edge should be on the inside, if anything, turn it over.
10. A gasket that is torn must be removed. It will stay in place thanks to the lubricant on the holder.
11. Lubricate the edge with engine oil.
12. Also lubricate the crankshaft flange with engine oil.
13. Place the working edge onto the flange.
14. Tighten the bolts.
15. Reinsert the crankcase and bushings.
16. Replace the flywheel and clutch.

The process of disassembling the gearbox
is ready, the replacement of the VAZ 2110 gearbox seal has been successfully completed.

Let your machine run for a long time and not leak. A good owner's car is always in excellent condition. So it all depends on you! Monitor and check, take it for diagnostics on time if necessary. And try not to spend a lot of money on service centers, but also don’t try to do everything yourself if you don’t understand this area!

Why do they need to be replaced?

The only reason for removing them and installing new parts can be wear of the edge of the valve seals, which is used to compress the valve stem. During engine operation, they perform a huge amount of work, experience high temperature loads and exposure to an aggressive environment. This cannot but affect their resistance and durability. Most of these spare parts are based on rubber, which, under the influence of all these negative factors, begins to harden, the working edges begin to crack, wear out and wear out.
