When is it necessary to change the oil in a VAZ 2107 gearbox?

According to technical regulations, the oil in the rear axle gearbox of the VAZ 2107 must be replaced every two years. As a rule, special gear oil is used for replacement. It is recommended to periodically change the oil in summer and winter, immediately before actively using your car.

Changing the oil in the rear axle gearbox of a VAZ 2107 must be done on a hot engine (after 5 kilometers), so that it warms up faster and the glass from the crankcase. Next you should do the following:

1. Unscrew the drain plug and completely drain the old transmission oil from the gearbox housing. If the used oil has a characteristic black color or contains silver grains, this indicates that the gearbox is contaminated with metal filings, i.e. about its malfunction. To fix this problem, you need to remove the gearbox and take it to a service center.

2. Thoroughly rinse the gearbox to remove any oil deposits. For maximum efficiency, flushing is carried out with oil with a high viscosity level.

3. Open the filler plug and use a regular syringe to pump new oil into the rear axle gearbox. The normal oil level is the one that corresponds to the upper edge of the filler neck. After adding oil, tighten the plug tightly.

At the end of the oil change process, you should check whether the breather is dirty. If necessary, it must be cleaned with a special brass brush.

Most owners of the "Seven" fill the gearbox with transmission oil recommended by the manufacturer. In 2107, several types of gearboxes are installed at the plant. They all require high quality lubrication. Only in this case will the box work reliably and for a long time.

In the service book, the manufacturer indicates several viscosity levels:

• SAE80W85,
• SAE75W90,
• SAE75W85.

Similar to motor oils, transmission oils, in addition to the viscosity coefficient, are divided into groups. In the VAZ 2107, professionals advise filling in:

• GL-4,
• GL-5.

The first group includes motor oils that contain a large number of special additives. This type is optimal for gearboxes with a large number of gears.

GL-5 brand oil is designed to lubricate rotating gears operating at a certain angle, that is, hypoid gears.

In the VAZ 2107, the rear axle gearbox has such a transmission. GL-5 is ideal for gearbox lubrication. The car manufacturer recommends replacing the lubricant in the gearbox together with changing the fluid in the manual transmission. Therefore, car owners use only one type of oil, pouring it into the box and gearbox.

In principle, no negative effect will occur. The properties of GL-5 allow it to be used in gearboxes. In addition, the compositions of this group were specially designed for use in extreme conditions.

Influence of viscosity grade

If the VAZ-2107 will be operated in temperate climate areas, where summers are constantly hot and winters are quite cold, then it is recommended to fill the manual transmission with all-season transmission fluid - SAE75W90. It can operate in a wide temperature range (-40/+45). Moreover, the performance qualities of the oil always remain unchanged.

When purchasing lubricant for manual transmission, you must take into account your place of residence. Each region has its own climatic conditions.

For example, SAE 80W85 can be operated in the range from +35 to -26 Celsius. Some regions require a wider range, so it is important to consider these values ​​when purchasing.

What kind of oil to pour into the VAZ 2107 bridge

Which one to pour oil into the VAZ 2107 gearbox?

In this article we will help you find out which oil is best suited for the VAZ 2107 gearbox and how much should be changed? Owners of these Russian cars are often asked such questions, because who should know these subtleties.

What kind of oil should I pour?

The majority of people add oil to the VAZ 2107 gearbox on the advice of the manufacturer. These Russian cars were equipped with four- and five-speed gearboxes, which required high-quality lubrication for reliable and long-lasting operation. In the viscosity grades and oil groups that we will look at below, first we will look at some brands of lubricants that can be refilled:

• UFALUB UNITRANS 85W-90;
• LUKOIL TM-5 85W-90;
• SAMOIL 4404 80W-90 or 85W-90;
• FAIR SUPER E-80W-90 or T-85W-90;
• TNK TRANS GIPOID 85W-90 or 80W-90;
• AGIP ROTRA MP 80W-90 or 80W-95;
• NORSI TRANS 80W-90 or 85W-90;
• NEW SUPER T 80W-90;
• SPECTROL FORWARD 80W-90;
• MP GEAR LUBE-LS 80W-90 will be 85W-140 (GL-5).

Oil classification

Each canister of transmission oil for the VAZ 2107 has certain properties that indicate the brand and viscosity group.

Oil groups

To choose which oil to fill the VAZ 2107 gearbox; You need to know the groups of these lubricants:

1. GL-4. The VAZ 2107 gearbox contains many additives. For the most part, these lubricants are used in cars with manual transmissions, which operate at high speeds with low torque, as well as at low speeds with maximum torque.
2. GL-5. This oil for the VAZ 2107 gearbox is designed for so-called hypoid gears (gears rotate at an angle). In these Russian car models, the hypoid gear is located inside the gearbox, so the gearbox is only capable of filling with GL-5 oil. Such oil is also poured into the box, but only in accordance with impressive performance criteria.

Viscosity grades

Choose which gear oil is best for VAZ 2107 ; you need to determine the viscosity class:

1. SAE75W90. This class includes semi-synthetic or synthetic oils that are suitable for use in all weather conditions. The lubricant can operate at temperatures from 40 to 35 degrees Celsius. Such oils can be used in cars operated in the harsh conditions of our country.
2. SAE75W85. This viscosity grade is also suitable for year-round box use, and temperatures to maintain performance range from 40 to 45 degrees.
3. SAE80W85. Oils of this viscosity are boiled at 35 degrees and frozen at 30 degrees or more.

You can read the separate article on oil changes for detailed video instructions.

Mineral oils

The most important and almost the only advantage of mineral oils. this is a low price compared to synthetic and semi-synthetic ones. For example, a four-liter can of mineral oil in a VAZ 2107 box costs about 400 rubles, and a similar semi-synthetic canister costs more than 1,000 rubles.

The lubricant composition has good lubricating properties, so you can drive it without replacement for up to 60-70 thousand kilometers. At the same time, in winter, such oil freezes in the cold and makes it difficult to start a cold engine.

Semi-synthetics and synthetics

The only drawback of this gear oil for the VAZ 2107 is its relatively high price, compared to ordinary mineral water. An average canister costs from 1000 to 1500 rubles. The disadvantages are limited to this, and when it comes to the advantages, they include high-tech lubricants and additive contents that reduce wear on transmission components while extending the life of the transmission.

The freezing point of these oils is much lower, so they are suitable for use in severe frosts. You can release the clutch pedal a few seconds after the power unit is engaged and the transmission will operate normally. Fat heats up faster and returns to normal fluidity compared to mineral fat.

READ How to Change the Release Bearing on a VAZ 2114

Some say that synthetic gear oil for the VAZ 2107 can squeeze out oil seals and leak from cracks. This is not true and if this happens it is a coincidence and the real reason lies in the obviously worn out gearbox.

How much oil do you need?

Many owners of domestic cars are interested not only in pouring oil

in the VAZ 2107 box, but also as much as needed. It is important not only how much oil is in the box, but also how much it gets into the transmission during a change.

In cars with a four-speed gearbox, the gearbox contains only 1.35 liters of oil, while in the case of a five-speed gearbox the capacity reaches 1.6 liters.

Source

Which oils are more suitable for the VAZ 2107?

In principle, any oil can be poured into the “seven”. The highest quality will, of course, be synthetic. Mineral water or semi-synthetic water will also not do any harm.

The cheapest is mineral liquid. However, it has a significant drawback - it begins to freeze quickly in cold weather. As a result, it is difficult to start the engine in sub-zero weather. You have to depress the clutch when starting the car.

Synthetics and semi-synthetics thicken less on cold days. However, their consistency has characteristic differences. Synthetics have high fluidity, which is why they are used in new manual transmissions. It begins to leak even with the smallest defect in the sealing gasket.

Semi-synthetic oil is thicker. Therefore, it is used in the manual transmission of a car that has covered more than 100,000 kilometers. If, after filling, the semi-synthetic material begins to ooze, then it is time to replace the failed parts.

Of course, each driver decides for himself which oil to use. But in any case, it is necessary to take into account all the nuances described above. Lubricant characteristics must comply with the manufacturer's recommendations. Replacement is carried out in accordance with the specified regulations. As a result, the gearbox will operate without repair for a long time.

Greetings) Of course, the oil in the axles changes depending on the mileage, but the car was recently purchased, what and when the previous owners filled in the axles is unclear, so I decided to change everything. To do this, I purchased 3 liters of Liqui Moly gear oil with a viscosity of 75W90 and 6 cans of Step-Up universal cleaner.

1) Clean the gearbox cover with a wire brush to remove any adhering dirt.

Something like this.

From under the dirt appeared the nameplates, in this case 3.73 (gear ratio).

Part number and year of manufacture (2004)

2) Unscrew the filler plug (3/8″ square). You should always start with the filler plug, because if it doesn’t come off, it’s better not to start.

3) Look how black the oil is.

4) Unscrew the cover bolts (head 17/32 - approximately 13.5 mm).

5) Remove the lid and drain the old oil. Be careful, don't get wet.

6) Thoroughly spray all the insides of the bridge with cleaner (you can use any automotive aerosol).

7) Use a wire brush to remove any remaining old sealant.

Once again we spill everything with cleaner.

9) Use a rag to collect the remaining cleaner from the differential housing.

10) Thoroughly blow out all the insides with compressed air (the task is to completely dry the remaining cleaner).

11) Moving on to the lid, it also needs to be thoroughly cleaned of sealant and dirt.

12) Wash and dry the lid.

Do not skimp on sealant; purchase only high-quality high-temperature automotive sealant.

13) Apply sealant.

The sealant must be applied in an even roller with a diameter of about 6 mm without breaks. The holes should be bypassed from the inside.

14) Carefully, trying not to lubricate the sealant, install the cover in place.

15) Tighten the fastening bolts with a torque wrench (torque 41 N*m). Carefully wipe off excess sealant with a rag. Do not rush to pour oil right away, let the sealant dry.

With the rear gearbox everything is exactly the same. The only thing is that its lid turned out to be more rusty. Therefore, it was decided to sandblast it.

Cover with soil.

And paint it.

Now she is already in her place.

I will describe the process of pouring oil in words - bring the car suspension into working position (support it from below or put it on the wheels), pour oil through the filler hole to the level of the plug (until it starts to pour back out), replace the plug (lubricating it with a thin layer of sealant). I hope this article is useful to you.

Ps I apologize for the poor quality of the photos, I took the photos on my phone.

What kind of oil to pour into the rear axle gearbox of a VAZ 2107

How much to fill?

Another important point is the amount of oil needed. Before answering the question - how much oil should be poured into the gearbox of a walk-behind tractor, for example Crosser, Viking, Forza, Sadko, Don, Huter, Profi, Plowman, Champion, Carver, you must first check the oil level in the gearbox. To do this, you need to perform certain actions:

• It is necessary to place the walk-behind tractor on a flat surface so that its wings are strictly parallel to this surface.
• We take a wire or rod about 70 cm long, which will act as an oil dipstick.
• We bend the improvised probe into an arc.
• We insert the resulting dipstick into the filler hole to the very end, i.e. all the way. After that we pull it back out.

If the wire is 30 cm deep in oil, then this is the optimal indicator, i.e. no need to add oil. If it is a little less, then it is necessary to top up within these values.

If the gearbox is completely dry, then you will need at least two liters of gear oil.

Checking the level and condition of the oil in the gearbox

The level and condition of the oil in the gearbox is checked “cold”, when all the liquid collects in the crankcase.

The oil should be at the level of the filler hole, 2-5 millimeters below.

To check, unscrew the filler plug and use a stick, wire, finger, or other improvised means to find out the level. The condition can be checked here by taking a small amount of liquid with a syringe and tube.

You can also assess the condition of the lubricant by unscrewing the drain plug for a few seconds. Tighten the filler first, so the oil will flow much more slowly. If the car has been sitting for several hours before, all foreign particles will settle in the crankcase, and you will get a clearer picture of the condition of the oil.

The presence of metal particles in the waste indicates that the gearbox components have a high degree of wear, and serious repairs and replacement of parts may soon be necessary.

Checking the oil level

Control checks of the fluid volume in the gearbox should be carried out every 10 thousand kilometers, as well as when malfunctions or visual leaks occur. Checking the oil level in the rear axle is quite simple. To do this, you will need a container with a volume of about one and a half liters, a 17mm wrench and a screwdriver. The next steps are:

• the car is placed on a viewing hole, overpass or lift,
• the filler plug is cleaned of dirt,
• use a 17 wrench to unscrew the filler plug,
• The oil level is controlled with a screwdriver: the liquid should reach the edge of the hole.

If there is insufficient protective liquid, it is necessary to add it using a syringe or other device.

What and how much to fill

It is best to fill the gearbox with gear oil recommended by the manufacturer. Information is indicated in the technical documentation, and it is very important to focus on compliance with the API class.

Almost all modern automakers require the use of oils of at least GL-4 and GL-5 in their transmissions, gearboxes and transfer cases, which contain extreme pressure and other additives and are adapted to work in the most severe conditions.

If you don’t know what kind of oil and how much is poured into the gearbox of your car, look for it in the table. We have collected information on approvals for various vehicles from many available sources.

If the car has 2 or 3 axles, then the total amount of fluid is indicated.

LSD (Limited Slip Differential) - self-locking differential, or limited slip differential.

How to fill oil into a walk-behind tractor gearbox

Before pouring new oil into the gearbox, you need to drain the old fluid . This is exactly how the oil is changed in the gearbox of the Salyut walk-behind tractor, a video of which can be found on the Internet, as well as other models of walk-behind tractors.

The algorithm of actions will be as follows:

• The walk-behind tractor needs to be installed on some hill so that the oil can be easily drained from the gearbox.
• There are two plugs on the gearbox - a drain plug, which is located at the bottom of the gearbox, and a plug that closes the oil filling hole. First, unscrew the filler plug, which is located on top of the walk-behind tractor body (at the gearbox).
• We take a sufficiently capacious container (an old bottle of transmission oil will do), and then place it under the gearbox drain plug.
• Carefully unscrew the drain plug , after which the oil will begin to flow into our container. After waiting until the oil has completely drained, screw the drain plug back in. Then tighten it with a spanner of a suitable diameter until it stops.

Oil filling process

• Insert the funnel into the filling hole. Then we take the appropriate gear oil to fill the gearbox.
• Having filled the reducer to the optimal level, screw the plug back. This plug is equipped with a special dipstick, and its length is approximately 10 cm. After we have filled in the oil, we need to check its level. To do this, we tighten this plug-dipstick, after which we unscrew it again and check it.
• If the oil is at the tip of this dipstick, then there is no need to add any more .

As a rule, the oil change procedure must be performed every 100 hours of operation of the walk-behind tractor. In some cases, this procedure must be performed every 50 hours.

In other words, the frequency of oil changes depends on the model of the walk-behind tractor, so all the necessary information is in the accompanying documentation for the walk-behind tractor.

Change of oil

It is better to replace it after traveling a short distance (5-10 kilometers). This will allow the oil in the gearbox to warm up and become less viscous.

The car should be in a horizontal position; it is most convenient to work in an inspection hole, on an overpass or using a lift. This will make it easier to get to the gearbox. Use a wire brush to clean the surface around the filler and drain holes.

It would be a good idea to pay attention to the condition of the oil seals; if they wear out, oil may leak out of the gearbox. If smudges are visible in the area of ​​the seals, it is also better to change them immediately.

The most loaded unit in a VAZ 2107 car is the rear axle gearbox. But with proper assembly, installation and timely maintenance, it can last longer than even less loaded units. As the instructions indicate, the oil in the rear axle gearbox and gearbox should be changed after break-in, then after a run of two thousand kilometers and subsequently every sixty thousand kilometers. The design of the gearbox of a VAZ car uses a special type of hypoid transmission with offset axes. This engagement reduces the noise level when grinding surfaces, but the sliding that occurs along the contact line of the teeth can lead to the risk of jamming.

Using special gear oil in the gearbox can eliminate it. The mixture contains extreme pressure additives, class GL-5. This oil is called Hypoid.

The volume of oil poured into the gearbox is 1.35 liters. Changing the oil in the rear axle gearbox of a VAZ 2107 is carried out according to the same algorithm as the gearbox oil. Replacement must be made before operating the car in winter and summer. For these seasons, the oil has a different viscosity. In winter it is low, and in summer it is high.

Oil change instructions

You can replace the gearbox lubricant in an inspection pit, overpass or lift. Before driving the car into the pit, you should drive a little and warm up the axle fluid. You should also prepare in advance a tool (a set of keys and screwdrivers), containers for working, protective gloves, rags, a special syringe or a device with a hose for pouring.

Changing the oil in the rear axle gearbox of the VAZ-2107 is performed in the following order:

1. Clean the drain and filler plugs from any dirt.
2. Using a 12mm wrench, unscrew the drain plug.
3. Drain the old gear oil into the prepared container. Remember that the liquid will be hot after warming up.
4. Tighten the drain plug.
5. Unscrew the filler plug.
6. Pour in enough oil to reach the bottom edge of the hole.
7. Tighten the filler plug. Make sure there are no leaks.

Changing the oil in the rear axle gearbox of a VAZ

• There is silver dust in the mixture. If there are metal grains instead of dust, this indicates serious damage to the car. You can't get by with just an oil change.
• Coffee or black oil color. This indicates that water has entered it or the additives in the solution have been destroyed.
• You can change the oil in the VAZ 2107 axle gearbox yourself.

Tip: The oil should be drained after the car has been driven so that it is hot and drains well from the crankcase. But you need to be careful, the temperature of the liquid can reach 90 degrees.

Work order

So:

• Unscrew the plug in the hole for filling the oil with a key “17”.

• Place a container under the drain hole to collect used oil.
  .
• Use a hex wrench to “12” to unscrew the drain plug to remove the used oil.
• After the liquid has completely drained, the drain plug is screwed into place.

Advice: If the oil drained from the gearbox housing has a dark color or metal particles, the rear axle gearbox must be washed.

• To flush, you need to fill in about one liter of a mixture of thirty percent kerosene with gear oil. Instead of kerosene, you can use diesel fuel.
• One rear wheel is lifted, first gear is engaged and the engine is started.
• After three minutes, the washing mixture is drained.
• For filling, it is better to use an oil blower or a lever grease gun. If you don’t have them on hand, you can use a large plastic syringe with an elastic tube attached to its end.
• 1.3 liters of special transmission oil is poured into the gearbox.
• It is necessary to ensure that its level reaches the lower edge of the filler hole.

After filling the oil, the breather is checked and cleaned of dirt. This device is necessary in order to relieve excess pressure in the gearbox that is formed when the oil heats up and when its level rises. All operations for changing the oil on a VAZ 2107 car can be clearly seen in the video.

Why do you change the oil?

The rear axle gearbox is a mechanism that is subjected to a number of different loads. Through these loads, destructive actions occur. To avoid accelerated wear of gearbox parts, it is necessary to use a special lubricant. This lubricant is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear and overheating, and also cleans the teeth from chips and metal dust.

It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, thermal energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, when the gears rub, the teeth wear out, resulting in the formation of chips and metal dust. If you do not change the lubricant in the gearbox for a long time, the amount of metal shavings and dust will only increase, which will lead to accelerated wear of the rubbing parts.

When to change gear lubricant

Changing the oil in the rear axle of a VAZ 2107 should be done regularly, but there is no specific threshold. It all depends on many different factors, but the manufacturer of a domestic car recommends performing this procedure every 60 thousand km.

Some of the main factors that influence the timing of oil changes are:

1. Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
2. Vehicle operating conditions. If the car is used in rural areas where there are poorly paved roads, dust, and dirt, then replacement should be done more often.
3. Lubrication quality. It is recommended to fill the rear axle of the VAZ 2107 with special high-quality oil. If you pour low-quality lubricants into the gearbox, you will need to replace them much more often.
4. Operating a vehicle with a trailer. The wear of the device parts will accelerate if the car is operated with a trailer in which cargo is transported.

Features of lubricant selection

It is recommended to fill the rear axle gearbox of the VAZ 2107 with semi-synthetic gear oil. It should have viscosity parameters 75W-90. This is a universal lubricant option, which is usually poured into the gearbox.

Special gear oil in the gearbox improves the quality of parts and also reduces their wear. Not every G7 owner knows how much oil needs to be poured into the gearbox. The lubricant volume for the gearbox is 1.35 liters. It is poured through a special filler hole (on the side), using a technical syringe. You must first drain the old lubricating fluid, for which there is a special drain plug at the bottom.

Steering of a VAZ 2107 car

On the VAZ 2107 model, the steering has a safety design with an articulated-lever steering wheel drive and a worm-roller gearbox.

• The steering gearbox is secured with three bolts in the engine compartment on the left side member.
• An adjusting screw installed on the top cover of the gear housing can be used to adjust the gap in the engagement of the double-ridge roller and the worm built into the structure of the device.
• Approximately 0.2 liters of oil is poured into the steering gear housing.
• To fill the oil, there is a filling hole on the top cover of the gearbox housing. There is no hole for draining the oil; fluid is only added to the VAZ 2107 if necessary.

Filling oil in the steering gearbox

Before adding oil, check the oil level:

• The vacuum booster is removed.
• Using a key set to “8”, unscrew the plug for filling oil into the gearbox, which has a conical thread.

• A special rod is used to check the oil level. To do this, the rod is inserted all the way into the gearbox, as shown in the photo.

• From the top edge of the filling hole, the oil level should be at a depth of 15 millimeters.
• If you need to change the oil in the steering gear of a VAZ 2107, then use a spanner wrench to “13” to remove the four bolts that secure the lower cover of the gearbox.
• Just slide the lid and pour the oil into the container.
• The cover is put in place, secured with bolts and new oil is poured.
• The plug is screwed into the filler hole.

Timely oil changes in the main components of the VAZ 2107 will increase its service life without costly repairs. And the price for oil changes is acceptable for all car owners.

Algorithm for changing the oil in a walk-behind tractor

Before using a new lubricant, it is important to clean the gearbox of the compound used.

The lubricant should be replaced immediately after using the equipment, before the oil has had time to cool. You can quickly change the oil yourself using the following scheme:

1. The walk-behind tractor is installed horizontally;
2. Two plugs are installed. Through one, the already used composition is drained, the second is used to fill in new oil;
3. The cap is unscrewed to fill in the lubricant. A wide container is installed under the drain hole;
4. The drain cap is unscrewed until all the used oil flows out;
5. The drain cover is screwed in until it stops with a spanner wrench;
6. The funnel is inserted into the fill hole and new oil of the appropriate brand and desired temperature is added;
7. The lid is screwed on. You can use a special probe to check the amount of product poured.

You can learn more about the specifics of the replacement procedure from the introductory video.

If the equipment is operated under normal conditions, the oil in the gearbox is changed once every hundred hours of operation of the walk-behind tractor. When working around the clock, replacement is done every fifty hours. This way you can prevent various breakdowns of agricultural machinery.

Further, replacement once every 250 hours of operation is sufficient.

The process of changing the oil in the gearbox

Changing the oil in the gearbox is carried out simultaneously with replacing the transmission. Three main reasons that indicate a fluid change in the gearbox:

• Corrosion of metal;
• The wear of gear teeth increases;
• Accumulation of wear products in the lubricant.

In addition to the main factors requiring replacement of the mixture, there are additional reasons. When buying a car secondhand, it is not known what kind of fluid was used to lubricate the gearbox system. There is also no exact data on when the mixture was replaced. The risk of exceeding the frequency of lubricant changes can lead to serious consequences.

The frequency of changing the lubricant in the gearbox is always in the vehicle operating instructions. In the absence of these recommendations, for cars with a manual transmission, the change interval is 50-60 thousand kilometers; with an automatic transmission, the mileage is two times less - 25-30 thousand kilometers.

The timing of lubricant changes also depends on the operating conditions of the vehicle. If driving conditions are difficult, change the oil more often. Changing the oil in the VAZ 2107 steering gear is carried out in compliance with safety regulations.

Work is carried out in a viewing hole or overpass, away from children, wearing special clothing and rubber gloves. Before you start changing the fluid, the power unit must be warmed up, this will increase the fluidity of the lubricant and make it much easier to drain.

List of necessary tools for changing fluid:

• Set of wrenches;
• Hexagon 12;
• Latex gloves;
• Rag;
• Container for draining used lubricant;
• New oil;
• Syringe or hose.

Having prepared everything necessary for changing the oil and warming up the power unit, you can begin the main process.

First stage

Having installed the car on the inspection hole, you can begin draining the old oil from the gearbox on the VAZ 2107. The procedure is carried out in the following sequence:

• Remove dirt from the drain and filler plugs;
• Place a container for draining under the drain plug;
• Unscrew the drain plug with a 12 key;
• Carefully drain the old oil;
• Tighten the drain plug.

Draining the oil is done with the engine warm; work must be done with caution to avoid burns. The liquid must drain completely, since heavy suspensions are always found in the thickness of the sediment, which drains last.

Second phase

The gearbox is flushed during the fluid replacement process. To flush the rear axle gearbox, you need to mix transmission or engine oil with diesel fuel. The proportion should correspond to 3: 1. Washing consists of the following sequence of actions:

• Draining old grease;
• Cleaning the system from dirt, sediment and mixture residues;
• Wiping all containers and cases;
• The prepared mixture is poured into the system;
• Next, you should jack up one wheel, start the engine, switching to first gear;
• Wait a few minutes;
• Drain the flush.

The gearbox is flushed once every 4–6 months, when undergoing scheduled repairs or replacing transmission fluid.

Third stage

After draining the waste and flushing the gearbox, you can fill in new oil. The process of filling new transmission fluid is performed in the following sequence:

• Unscrew the filler plug;
• Pour lubricant to the bottom edge of the hole;
• Tighten the filler plug;
• Make sure there are no leaks, if necessary, repair the leakage of the mixture.

The fluid level in the gearbox must not be lower than the oil level mark. There should be no lubricant leaks in the rear axle gearbox. If leaks are detected, they should be repaired immediately.

Answers (1)

Transmission oils with a viscosity of 75W90 or 80W90 can be filled into the Gazelle rear axle gearbox.

For example, Shell Spirax S3 or Liqui Molly 75W90. In general, you can use any manufacturer; if you take an imported one, it will be better than what was poured.

In terms of fluid volume, if the gearbox requires up to 2 liters of oil, then the axle needs a little more than 2 - usually 2.3 liters.

Replacement frequency is about 70-80,000 km.

A car like the Gazelle is often used for work. If the vehicle is properly maintained, then the return will be appropriate. Among the necessary maintenance, there must be a procedure for changing the oil in the rear axle.

Differences between oil changes in other VAZ models

If extraneous sounds and knocks appear that are felt through the steering wheel, on a VAZ 2106, changing the oil in the steering gear is a mandatory and urgent process. Having installed the machine in the inspection hole, the first step is to check the lubricant level in the gearbox.

The difference between the change is that the gearbox on the VAZ 21213 does not have a drain plug, like on the VAZ 2107 and 2106. To change the oil in the VAZ 21213 steering gear with a volume of 0.2 liters, you need to prepare two syringes. The liquid is sucked out through one syringe, and filled in using the second.
