For quality protection from friction and damage to rubbing parts in the gearbox of a Gazelle car, it is necessary to control the level of lubrication in it. Therefore, you need to know how to determine how much oil is in the Gazelle box and what kind of lubricant should be poured into the gearshift device.

How often an oil change is required
If you carefully read the operating instructions for a GAZelle 402, 405, 406, 2705, 3302, Next, Business and other models, it will become clear that the transmission oil in the gearbox of this car should be replaced after 60 thousand kilometers.
In addition, the frequency of lubrication changes is affected by the conditions in which the car operates. Basically, GAZelle cars are operated year-round and have high mileage and the working conditions of the machine are not always ideal.
Choosing a lubricant
The smooth operation of the gearbox, as well as the timing of the replacement, largely depend on the quality and characteristics engine oil.
On the video from the user Mechanic you can learn more about the choice transmission fluid for Gazelle cars.
Choosing a lubricant for a GAZelle gearbox should be based on the following factors:
- Machine manufacturer's recommendations for lubricants which are subject to certain requirements. It is best to use more expensive and quality oils, since saving money on lubricants, you can spend a lot on repairing the unit.
- When choosing an oil brand, it is necessary to take into account not only the operating conditions of the machine (temperature environment, state pavement, total mileage), but also the manufacturer of the transmission fluid, as well as its reputation in the automotive market.
- You should purchase a "transmission" about 1 liter more than is required for replacement. It will be needed later when topping up, and you need to add only the oil that was previously filled in.
A lot when choosing an oil depends on the climate in which the car is operated. In areas with low temperatures air for the winter is filled with a liquid of lower viscosity than in the southern regions.
Not always in service books there are recommendations for the car lubricating fluid. For example, the instruction manual for a car with UMP engine does not provide specific guidance on oil selection, only a viscosity that meets the SAE 75W standard is recommended.
Trans Gipoid 80W90 SUPER T-3 85W90 Castrol 75W140 HD SAE 85W140
These indicators correspond to the oil of the following brands:
- Castrol 75W140;
- Magnum 75W80;
- Total 75W80;
- Manol 75W80.
The presence of mineral additives in lubricants that meet the SAE 75W standard can improve their characteristics, including density and viscosity. Such oils solidify at a temperature of about -45 ° C, which allows them to be used in almost all regions of the Russian Federation.
About level control
The lubrication level of the unit is checked after every 20 thousand km. This must be done even when no visible leaks are found. If the level of the lubricating fluid has dropped for some reason, the gear oil is added to the gearbox crankcase.
The operating instructions for GAZelle cars do not indicate a specific amount of lubricant to be added to the gearbox, since, depending on the modification of the car, the amount of oil can be in the range of 1.2-1.6 liters. Therefore, we advise you to purchase liquid in a 2-liter canister, its possible excess will be useful for topping up.
Before you start checking the fluid level, you need to thoroughly clean the breather, its cover and the nearby surface of the gearbox housing, after which you should turn the plug several times. The amount of grease is on the lower edge of the filler hole, so cleaning from dirt is essential.
Let us consider in more detail the process of controlling the oil level in the gearbox of a GAZelle car:
- It is only necessary to check the quantity at a warmed-up gearbox. To do this, it will be enough to drive 10-15 kilometers.
- The machine must be installed on a flyover or viewing hole, even a slight inclination in the horizontal plane is unacceptable.
- It is necessary to allow the grease to drain from the walls to the bottom of the crankcase. During this time, thoroughly wipe the filler cap, which is also a control one, with a rag.
- It is necessary to unscrew the plug and observe the hole. If a thin stream of lubricant flows through it, this is not evidence of a normal oil level. Next, you need to add fluid to the gearbox with a syringe and check again.
- Stopping the flow of lubricant after topping up will indicate normal level fluids in the system.
- Now you can tighten the plug and continue to operate the car.
Important! It is only necessary to add lubricant to the gearbox of a car of the type that was filled earlier.
It is unacceptable to operate a car with a low oil level in the Gazelle Next checkpoint and other models. Since insufficient volume can provoke air locks, which will affect the amount of lubricating fluid supplied to the gears and gearbox bearings.

Replacement instructions
If the required amount of gear oil for replacement is prepared, the place of the operation is selected, then you can change the "transmission" in the box.
Required Tools
To replace, prepare:
- container for collecting "working off";
- syringe to pour new lubricant;
- cleaning material;
- new filling oil.
In some cases, flushing the gearbox housing will be required. This will be indicated by the presence of metal chips on the drain plug magnet. Then you should additionally prepare about 1 liter.
On the video from the Gazelists of Ukraine channel, you can see about changing the lubricant at the Gazelle checkpoint.
About the operation order
How much oil is in the GAZelle box - we found out, let's talk about how it is replaced. Such an operation is carried out only at a warmed-up gearbox of the car, as this allows you to completely drain the "working out".
- The machine is installed on a viewing hole or overpass. Stops are placed under the wheels.
- Thoroughly clean the drain and filler cap from accumulated dirt.
- Unscrew drain plug, after substituting a container for collecting "working off" under the crankcase.
- Drain the grease, this will take about 20 minutes.
- The drain plug is inspected for the presence of metal chips. If it is noticed, flush the gearbox housing.
- The cleaned cover is wrapped in place and the filler is unscrewed. Depending on the vehicle configuration, it can be located both on the left and on the right side Checkpoint.
- The required amount of lubricant is added to the open filler hole with a syringe. Continue pouring until oil flows out of the hole.
- The cork is wiped and set in place.
If there is no syringe at hand, then you can change the oil without it. In this case, new grease is poured through the hole for the gear lever. Dismantling it will not be difficult. To do this, the protection in the form of a cover is removed, and then the lever is turned out. The required volume of liquid must be poured into the formed crankcase hole, observing its appearance in the control hole.

Replacement cost
Many owners of GAZelle cars change the oil in the gearbox on their own. In this case, the cost of the procedure will include only the price Supplies. In addition to new lubricant, flushing and solvent may be required. Oil will cost the buyer from 500 to 1000 rubles, flushing liquid- 400-700 rubles, solvent about 200 rubles. The purchase amount depends on the manufacturer, type of product and outlet.
Contacting a service center will cost a little more. In addition to the price of "consumables", the cost for performing the operation is taken into account. This number depends on the category. service center: the more popular it is, the more expensive it is. The car owner will need to prepare for payment from 500 to 1000 rubles only for work.
On the consequences of untimely replacement
During the operation of the machine, transmission oils lose their qualities:
- the anti-seize properties of the oil are reduced;
- lubricity deteriorates;
- the viscosity of the fluid decreases.
As a result, gearbox parts such as gears, bearings, synchronizers may fail. And the cost of their restoration will be several times higher than the price of gear oil and consumables.
Here I will describe the installation process of five step box gears on my Volga GAZ-24. So I bought a five-day ticket in Odessa from a teammate. While pyatistupka on the road decided to start writing this little article as new photos and information become available.
For now, I will lay out information on five-speed gearboxes manufactured by GAZ (for comparison, information is given on 4 st. Volga checkpoints):
Oil volume for five-speed gearbox Volga/Gazelle -1.2l. But everywhere on the Internet people flood more oil which improves lubrication, but may slightly increase fuel consumption and seal leakage. In principle, an oil reserve of 200-300 grams will save you from driving with a low level of oil in the box, which, in an imperceptible way for you, can leak through the shank, for example (after all, the quality of the oil seal is unpredictable). Recommended oil - synthetic or semi-synthetic for mechanical boxes gearshift gears. Oil class GL4. It is also possible to use oils class GL5 and mineral. Mineral water somewhat worsens the quality of lubrication, and in winter it increases fuel consumption. GL5 oils are more aggressive to synchronizers, and also prevent the synchronizer from working - film hypoid oil very resistant to shear and synchronous does not bite as it should, but slides. However, this oil protects the oil better from loads, especially in the heat in summer.

The main difference between the Gazelle five-speed gearbox and the Volgovskaya five-speed gearbox is the traction orientation of the GAZelle gearbox. For the Volga, these gear ratios are approximately the same as a four-speed, except for the first and fifth gears. The first gear on the five-speed GAZelle is very traction and there is a big gap with the second gear.
In general, in general, the box allows you to well realize the traction potential of low-speed engines. But in the case of intensive overclocking, the gap between the first and second is too big. With the Volga's five-speed gearbox, the situation is similar, but in general the box has a high-speed orientation. However, the first gear is more traction than on four-speed transmission, which allows you to move more slowly on the first one, it is easier to start with a trailer or tow. Fifth gear significantly reduces engine speed - by 20.6% when driving at high speeds. Also, with a working chassis, fuel consumption should drop on the highway by 5-10%, depending on the driving style and the selected speed.
And from the photo of my gearbox 31029:
So the box arrived at the place this week and installed on the car. From the nuances of the installation - the studs of the clutch housing are turned out. switch reversing(frog) is similar to that of a 4-mortar and all modern designs are constantly out of order. The gearbox support also fits from the 4-speed gearbox. Cardan left straight - without outboard bearing. The speedometer cable came up in length.
My forecast for gear ratios The checkpoint justified itself, in addition, the long third gear allows you to make difficult overtaking for the Volga - you can easily accelerate to 80-90 km / h on it (and the traction reserve is more than in 4th gear). The noise of the box as a whole in motion is lower, but on idling higher. There are opinions that the use synthetic oil treats noise, but it lacks a solid foundation and is more like a placebo effect. The nature of the engine noise has changed. The noise of the engine is less audible - either the rustle of the bearings at idle changes its perception, or the five-speed redistributes the exhaust sound into the cabin in another way. It is also possible that this is due to my self-made exhaust bracket, which somewhat isolates the exhaust tract from the gearbox.
By speed limit fifth gear can be used from 55-60 kilometers per hour. Naturally, you can forget about acceleration at such engine speeds. But if there is nowhere to hurry, then on gas engine you can save a couple of crumbs (detonation will get on gasoline).
In general, the impressions were divided - 80% positive, 20% negative. The downside is gear shifting. The second and first gears are very tight when moving from higher ones. Sometimes synchros don't work well. However, the box is not new, but the defects are standard for it.
Filled with new oil and installed spring support
The oil change interval is 60 thousand kilometers.
3. Place a container under the gearbox oil drain hole.
5. If the drained oil is heavily contaminated or contains mechanical impurities, do the following:
Pour 0.9 liters of flushing oil into the crankcase and install the oil filler plug in place;
- hang one or both wheels, engage 1st gear and start the engine for 2-3 minutes;
- drain flushing oil;
- wipe the oil drain plug and install it in place.
6. Fill the gearbox housing with fresh oil using a syringe.
Fill up to the level of the oil filler hole (1.2 l).
7. Replace the oil filler plug.
More:
We install the car on a flyover or inspection ditch.
We drain the gearbox oil immediately after the trip, until it has cooled down.
Unscrew the drain plug with a 12 hexagon wrench ...
And drain the oil into a wide container with a volume of at least two liters.
If the used oil is dark in color or metal particles are visible in it, we flush the gearbox, for which we install the drain plug in place, having cleaned its magnet from steel chips.
Then, with a 12 hex wrench, we unscrew the filler plug on the right side of the crankcase (for a car with a ZMZ-406 engine) ...
Or on the left (with the ZMZ-402 engine).
With an oil syringe, pour into the box about one liter of a mixture of gear or engine oil with 20-30% kerosene or diesel fuel and replace the fill plug.
Substituting stops under the front wheels, hang out rear wheel or the entire bridge.
Having turned on the first gear, we start the engine for 2-3 minutes.
Having installed the machine on wheels, completely drain the flushing oil (draining time is at least 5 minutes).
After cleaning the drain plug again, we wrap it with a key in place.
Having unscrewed the filler plug, fill the gearbox with fresh oil with an oil syringe. transmission oil to the level of the filler hole (1.2 l).
Having installed the filler plug in place, we wrap it with a key. Instead of a syringe, you can use a funnel with a hose.
