Oil in the transfer case and axles of the UAZ 469: when, how much and what kind to fill

Transmission oils for UAZ gearboxes, transfer cases and axles, classification of oils

Transmission oils are designed to lubricate parts of manual transmissions, transfer cases and drive axles. They create a strong lubricating film at the contact points of the parts of these units, which can withstand heavy loads.

Gear oils are defined and differentiated by classifications that are widely accepted today: SAE J306 for viscosity, such as 80W, 90, 75W-85 or 80W-90, and API, which contains a comprehensive assessment of gear oils for performance properties, such as GL-4 or GL-5 . In addition, along with the API specification, indicators according to the American military specification, denoted by the MIL index, may sometimes be used. For example MIL-L-2105A or MIL-L-2105B.

Features of the classification of transmission oils according to SAE and API

SAE viscosity grades with the letter W refer to seasonal oils for the cold season, for example 75W or 80W.

Accordingly, without W - to oils for warm summer time, for example 90 or 140.

However, since the resource of transmission oils is quite long, using seasonal oils in everyday use, changing them in units every six months, is very inconvenient and not economically profitable.

The API classification currently contains five categories - GL-1, GL-2, GL-3, GL-4 and GL-5, which show the applicability and quality level of gear oils. For example, in category GL-5 - oil contains extreme pressure, anti-wear and other additives, used for hypoid and other types of gears in gearboxes and drive axles of cars.

Transmission oils for UAZ Hunter and UAZ Patriot gearboxes

Several types of synchronized gearboxes can be installed on UAZ Hunter cars and all models based on it: a four-speed Russian-made, a five-speed ADS made in China or a five-speed DYMOS made in Korea. On the UAZ Patriot and all models based on it, only a Korean-made five-speed DYMOS gearbox is installed.

The plant recommends filling the four-speed gearbox with SAE 75W-90 gear oil according to API GL-3. The Chinese-made five-speed ADS gearbox and the Korean-made five-speed DYMOS gearbox are SAE 75W-85, API GL-4.

Transmission oils for mechanical transfer case UAZ Hunter and UAZ Patriot

When equipping a vehicle with a four-speed or five-speed ADS gearbox, the plant recommends filling the mechanical transfer case produced by UAZ OJSC with the same transmission oil as the box.

This is quite justified, since it is due to the fact that during operation, partial flow of oil from the gearbox to the transfer case is possible.

The oil level in the gearbox may drop by 8 mm. relative to the lower edge of the filler hole and will accordingly rise in the transfer case.

When the car is equipped with a Korean five-speed DYMOS gearbox, it is recommended to fill the mechanical transfer case with SAE 75W-90 gear oil according to API - GL-3.

Although there is no particular point in this, since oil from the DYMOS box also tends to flow into the transfer case, so it is more rational to fill both units with the same oil to prevent possible mixing of different oils.

Transmission oils for the front and rear axles of the UAZ Hunter and UAZ Patriot

In the crankcase of both axles, the manufacturer recommends using transmission oil SAE 75W-90 according to API - GL-5.

Answers (2)

According to scheduled maintenance, the transmission oil in the gearbox and transfer case must be changed at the zero and fifth maintenance, that is, at the first 2,500 km, and then every 40,000 km, regardless of the operating time.

As for the choice of fluid, the manufacturer recommends filling in oil with a viscosity grade of 75W-85. Owners do well with 75W-90 full synthetic gear oils with GL4-GL3 specifications. It is suitable for both manual transmission and transfer case.

The manufacturer recommended oils: SKG-F Top 75W-85, ZIC G-FF 75W-85, Hanval Incorporated SAE 75W 85 API GL-4. This is for mechanics.

For the transfer case - SAE 75W/90 oil according to API GL-3.

The Patriot box is very demanding on oil. It is strictly not recommended to fill in 75W-90 GL5 oils, which are common and available in all stores (only semi-synthetic and synthetic 75w-85 GL4). These oils have a destructive effect on the synchronizers and the box begins to growl when switching. (this is exactly the case when you ruin your porridge with butter). GL4 oils contain fewer additives and do not kill synchronizers. The mechanical transfer case was developed back in the USSR in the 70s under Nigrol. Therefore, it cannot be killed by any oil above GL3. The problem is that we fill the transfer case with synthetics, and not even the most expensive oil seals can hold it. Only a few lucky people have a dry Soviet transfer case. There is even a joke: if you have a dry transfer case, it means there is no oil in it.

What oil is needed for an SUV

When initially refueling the ZMZ Pro Euro 5 engine, used on the Patriot since 2022, original oil of 2 grades is used:

• synthetic Motor Oil Premium SAE 5W-40, SN/CF;
• semi-synthetic Motor Oil SAE 10W-40, SL/CF.

Oils to replace.
Synthetic based fluid is recommended for severe operating conditions. The type of lubricant filled into the engine is indicated in the accompanying documentation. When servicing a car at an official dealer, the engines are filled with original material recommended by the manufacturer.

When purchasing a used car that has been serviced by the previous owner itself, it is difficult to determine the type and viscosity of the lubricant in the engine. The existing liquid is drained, and the cavity of the power unit is washed with special oil. Then fresh substance is poured in accordance with the plant’s recommendations.

An additional criterion for choosing oil is the climate zone in which the SUV will be operated. The selection of the base is carried out taking into account the maximum and minimum air temperatures in summer and winter. Synthetic materials are suitable for operation at low temperatures because they retain fluidity and facilitate the procedure for cranking the shaft with the starter. The list of lubricants acceptable for refueling a gasoline unit is given in the table.

When using a synthetic-based fluid, knocking noise may occur from the hydraulic valve lash compensators installed in the gas distribution mechanism. The defect is observed on cars with mileage of more than 80 thousand km. New compensators allow the use of both synthetic and semi-synthetic oil. But the use of mineral-based lubricants is not recommended, since the design of the motor is not designed for the use of such substances.

The ZMZ 514 diesel engine (or the less common Iveco) requires the use of oils that meet the API CF-4 specification and higher. The lubricant container must contain an inscription confirming that the substance is suitable for use in diesel engines equipped with a turbocharger.

First oil change on a UAZ Patriot. The plant allows the use of substances with viscosity values ​​similar to those given in the table for a gasoline unit (with the exception of 0W-30 and 0W-40).

Let's start changing the oil

To change the transmission oil, you first need to acquire the following materials: two keys for 23 and 24, a technical container (the old oil will drain into it), a filling syringe, a new oil filter, new oil, rags, gloves.

The procedure for changing the oil in a UAZ Patriot manual transmission:

1. We drive 10 kilometers to warm up the engine to operating temperature.
2. We place the car on an overpass, or use a lift or inspection pit. In any case, it is necessary to provide full access to the bottom of the car
3. We climb under the car and place a technical container. The waste will flow into it
4. On the gearbox we find the oil drain plug, unscrew it with a 23 key, then observe the process of the used oil flowing out along with dirt and metal shavings
5. Wait for the old fluid to drain. After making sure that the oil has been completely drained, tighten the plug, first cleaning it and the hole from dirt and soot. The copper gasket on the drain plug may have deteriorated. In this case, you will have to install a new plug
6. Fill the box with new lubricant using a filling syringe. It is necessary to pour in a certain amount of liquid equal to 2.5 liters. You may need to add a little more oil later. So, let's put the plug in place. At this point, the process of changing the oil in the UAZ Patriot manual transmission has been successfully completed, and you can begin further operation of the car.

Why does the box “eat” oil?

There are several reasons for this. Firstly, the presence of road dust and dirt in the transmission oil. And as we know, UAZs are not bought for driving around the city - in 70 percent of cases they are prepared for full-fledged off-road driving, where they conquer fords and rivers. A UAZ mired in mud (this is, of course, a rarity, but even all-wheel drive does not save you from a deep swamp) easily “swallows” dirt, sand and water. By the way, the presence of even 5 percent of water can simply kill the transmission. To prevent this, motorists install a cover on the UAZ gearbox. It is able to protect the transmission from such factors.

Procedure

The procedure for replacing lubricant in Patriot transmission units is not particularly complicated, however, it requires patience and attentiveness from the performer. To complete the work in full, you will need to drain the used fluid from each of the system components one by one, replacing it with new lubricant. For this purpose, it is first necessary to prepare new oil in a volume sufficient for replacement, a set of car keys, containers for used fluid, as well as work clothes.

The task of replacing fluid in transmission units is carried out from the bottom of the car. In service centers, special lifts are used to ensure unhindered access to drain openings; at home, it will be enough to drive the vehicle onto a pit or overpass.

Before performing the operation, it is important to drive an SUV for about ten kilometers so that the lubricant in the system warms up to operating temperature. Under the influence of temperatures, it will become liquid and will merge faster and better from the aggregates.

Further measures are carried out in accordance with the work schedule for each transmission unit.

Changing the oil in axles

The procedures for changing the oil in UAZ Patriot axles do not differ in execution technology, so let’s look at the procedure for implementing the tasks using the rear axle as an example. In practice, you can successfully perform a replacement by following simple instructions from the car manufacturer:

1. Locate the drain and fill caps, which are located on the rear axle housing. First, you need to clean the surfaces adjacent to the openings with a metal brush from dirt to avoid it getting into the system.
2. Next, unscrew the filler plug to relieve pressure, after which you can unscrew the cover of the drainage hole, having previously placed a waste container under it.
3. While the oil is draining, the plugs must be thoroughly cleaned of metal shavings that may accumulate on the inside of the caps during operation of the machine. After the oil has drained, the oil drain plug is installed in place and clamped with the recommended force.
4. Using a technical syringe, lubricant is poured into the oil filler opening until it begins to flow out of the hole. This procedure will require about 1.3 liters of oil, depending on the quality of the waste drain.
5. Don't forget to tighten the filler cap.

The oil change in the front axle of a UAZ Patriot is carried out in a similar way, with the only difference being that the oil filler and drain plugs must be looked for on the front axle housing. The front axle housing will contain no more than 1.4 liters of lubricant. At this point, the procedure for replacing the lubricant in UAZ Patriot axles can be considered successfully completed. Then you can move on to changing the oil in the transfer case and gearbox.

Changing the lubricant in the transfer case

The methodology for changing the oil in the transfer case of a UAZ Patriot is practically no different from the procedure for changing transmission fluid in axles. To perform the procedure, you will need to find the drain and filler holes, clean the surfaces one by one from dirt accumulations and unscrew the filler plug. Then the waste is removed into the prepared container through the drain opening. Once the liquid has drained, you need to tighten the drain plug and fill the oil through the filling opening using a technical syringe to the limit, which will be a little more than two and a half liters in volume.

Along with changing the oil in the axles and transfer case, it is recommended to change the lubricant in the gearbox, the technology of which is the same as in previous situations. When pouring new oil into the gearbox, the level should be monitored using a special dipstick with which the car is equipped. After filling and running in the car, you will need to recheck the level in the gearbox; you may need to top up the oil to normal.

After replacing the lubricant in all transmission components, you need to start the car and drive it for several kilometers, after which you drive it onto the overpass again and check all the joints for fluid leaks, and if necessary, tighten the plugs more tightly.

How much to pour?

New fluid must be poured until it begins to flow from the top “hatch” - this is a signal that the level is at its maximum level. By the way, the remaining fluid is checked using the same principle - using a hex wrench, unscrew the top plug and look at the remaining amount with a dipstick. Even a wooden twig or a long nail can serve as a probe. The main thing is that the item is clean. If there is not enough oil, add it (but do not mix with different brands). Typically, UAZs use Lukoil or its equivalent, similar in name, Yukoil.

What oil is better to fill in UAZ Patriot

The documentation for the vehicle always indicates consumables and their modifications that should be used for replacement. Experienced mechanics do not recommend relying on the advice of a manager at a car shop on purchasing oil for a UAZ engine.

In general, for long-term operation of UAZ Patriot engine parts, semi-synthetic oil with the following parameters 5W30 is poured into it. This lubricant is suitable for both harsh winters and hot summer seasons. It does not turn into a viscous viscous liquid or become too thin after a run of 1000 kilometers.

Of course, many will say that the best lubricant would be 0W40, but it is expensive and not everyone can afford it. By the way, fully synthetic oil is not poured into an engine that has traveled more than 100 thousand kilometers. Despite the fact that synthetics have better parameters and properties that protect the UAZ Patriot engine from premature wear.

For example, when using a synthetic lubricant with a mileage of more than 100 thousand kilometers, the car owner may notice that there is a knocking sound from the hydraulic compensators. However, the use of mineral-based oils is not recommended at all. Since the engine is not designed to use mineral lubricants. Therefore, semi-synthetics are always suitable for engines such as ZMZ 409.

The manufacturer of this type of oil should be chosen from both foreign and domestic companies. The main thing is not to fall for a counterfeit lubricant. Since the oil performs the main function of protecting the engine from overheating and rapid wear of the mechanical parts of the engine.

If we consider lubricant brands in more detail, the leading ones are:

First of all, pay attention to oils from these companies. https://www.youtube.com/embed/PkyNc2cDNko

Which oil to choose

Some manufacturers, especially imported cars, use factory conveyor oil, which does not need to be replaced. This statement is wrong if we talk about the harsh Russian climate. The UAZ company knows about all the “delights” of weather conditions in Russia, and therefore recommends using only high-quality oil.

It is distinguished into three types:

• Mineral oil is the most affordable oil today. Recommended for use only with very high mileage. This is the thickest liquid that will perform well in warm climates, but in winter it will quickly solidify, resulting in problems with switching and starting the engine. Therefore, such a lubricant can be recommended only as a last resort, and only in warm climate zones.
• Semi-synthetic - this oil can be recommended for UAZ Patriot, but with minor reservations. It must be admitted that semi-synthetic is definitely better than pure mineral water, since it uses about 40% pure synthetic oil. The rest is supplied by mineral water.
• Synthetic oil is the highest quality oil available today. It has an undeniable advantage - the ability to effectively lubricate parts at almost any temperature range, including the most extreme climatic zones. In addition, this oil will last for a large number of miles.

When is replacement necessary?

The frequency of oil changes in each transmission unit is regulated by the manufacturer in the user manual. For cars that have just left the assembly line, the first change of transmission fluids should be performed no later than after five thousand kilometers traveled. Such a short interval is explained by the fact that after assembly, new structural parts are rubbed against each other during the running-in procedure, during which there is a possibility of the formation of small metal particles, the presence of which can negatively affect the operating life of the components and the machine.

Further changes of the emulsion in the gearbox, transfer case and axles are regulated by the manufacturer at intervals after every thirty thousand vehicle miles. It should be understood that the interval between procedures may vary depending on how high-quality the product is poured into the transmission, as well as on the operating conditions of the vehicle.

Flushing

To do this, you will need 500-700 milliliters of “mineral water” (not to be confused with water - this is oil).

Screw the hole from the bottom and pour it into the transmission through the top neck. Let the car idle for a while (4-5 minutes will be enough). The transmission gears must be in neutral. Next, we turn off the engine, substitute our canister and drain the oil by unscrewing the bottom “hatch”. Also remember that you cannot drive it due to its low viscosity - this can lead to scuffing, and, as a result, you will have to repair the UAZ gearbox.

Changing the oil in axles. — logbook UAZ Patriot Baby Patrick 2008 on DRIVE2

And so, I got to the bridges, or rather to changing the oil in them. I also needed to find out the reason for the large idle rotation of the flange, about 90 degrees, of the front axle in which the self-block is installed. The previous owners had no idea what company it was. I drove the car into a warm box, unscrewed the drain and filler plugs on the front axle and saw what was inside.

This kind of oil, or rather an emulsion, was in the front axle. Clear signs of water getting inside the bridge.

While the remaining oil was draining, I opened the diff cover, but to my regret I didn’t find anything terrible there, the gap between the main pair of gears is minimal and almost not felt, the bearings are also free of play, but all the free play is on the axle shafts and their drive in the self-locking unit. In other words, the reason for such idle speed lies in the design of the self-block, I realized this when I looked at the cross-sectional photo of the self-blocks and their operating principle. I didn’t take a photo because there’s nothing to see there, I replaced the gasket and put the cover back in place. And while I was putting the cap on the front, the oil was draining from the rear axle, the situation with the oil there was similar, it was also gray.

When the old oil stopped dripping from the bridges, I started pouring new oil.

Of course, I overpaid a little with the oil, in another store the same thing costs 100 rubles less, but the seller is a wooden consultant, unlike the store where I bought the oil. In total, I spent 1.25 liters on the rear axle, and approximately 1.4 on the front axle. I filled until the moment when oil began to flow from the upper filler hole; in fact, it is also a level indicator.

In total, 3 liters of oil were purchased for 1000 rubles per liter, a cover gasket for 110 rubles and sealant for 100 rubles.

PS before the replacement, a slight hum was heard from the rear axle, after the replacement I still don’t understand it due to slush on the road, it’s just not audible. Next in line is changing the oil in the gearbox and transfer case.

The gearbox on every car is an important component of any vehicle, so its serviceability is an important factor. The SUV also has a gearbox, thanks to which it is possible to move at different speeds. In addition to the main parts, the gearbox is filled with oil, which requires periodic replacement

In this material we will pay attention to the process of changing the oil in the gearbox on a UAZ Patriot. How to change the oil, when it is needed and what determines this period

Changing the oil in the front axle of the UAZ Patriot

According to the manufacturer's recommendation, it is necessary to replace the heated lubricant. To do this you need to drive 4–6 kilometers. Warm grease has a thinner consistency and flows out of the drain hole faster. At the end of the movement, the lubricant is replaced as follows:

Install the UAZ Patriot on a pit, lift or overpass. The site must be level, without a side slope;

• Immobilize the vehicle. To do this, shoes are installed under the wheels;
• Prepare a container for collecting waste material. The container volume must be at least 2 liters. To facilitate the process, it is necessary to select a container with a large neck;
• Unscrew the filler plug. This is necessary to supply air to the bridge cavity. If there is insufficient air in the cavity, a vacuum is formed. The plug is located below the middle of the crankcase;

• Unscrew the drain plug. It is located at the bottom of the crankcase. The plug is unscrewed counterclockwise. To open, a 12 mm hexagon is required;
• Clean the plugs from oil accumulations, dirt and metal shavings;
• Screw in the drain plug until it stops;
• Fill with new lubricant. The filler neck is located at the top. You need to fill in the lubricant using a specialized syringe;

Screw the filler cap until it stops.

UAZ Patriot refueling tanks

The design of absolutely every modern car necessarily requires the presence of a power plant, tank, gearbox, and other units and various parts that have their own volumes. It is in these same volumes that diesel fuel is placed, as well as brake fluid, of course, gasoline or antifreeze, but all the fluids listed for each individual model are individual. We invite you to learn in detail about the filling tanks on the UAZ Patriot, which is popular in our country, plus we’ll look at what they essentially are and how much this car model requires to fill certain mechanisms.

Patriot refueling volumes

UAZ Patriot refueling parameters correspond to the following values:

1. Fuel tanks. The left gas tank holds up to 36 liters of liquid fuel. According to the data in the instructions, the right tank has the same volume. Actual figures may slightly exceed those stated. This means that 1-3 liters more fuel can be filled into the tanks.
2. Engine lubrication system. The volume of this element is 7 liters. The lubrication system of the UAZ Patriot 31631 holds only 4 liters of oil.
3. Engine cooling and interior heating system. The tank can be filled with 12 liters of coolant. The radiator volume with longitudinal pipes reaches 14 liters.
4. Manual transmission. The capacity of this unit is 2.5 liters.
5. Transfer system housing. The tank volume of this part of the car is 800 ml.
6. Rear and front axles. The capacities of these SUV elements differ from each other. The front axle holds up to 1.4 liters of oil. The volume of the rear element is 1.5 liters. The actual capacity of the rear axle housing is slightly higher than stated. Filling with more oil will help maintain the functionality of this unit. All working parts of the system must be immersed in lubricant.
7. Hydraulic power steering column. For most modifications of Patriot cars, this figure is 1.1 liters. The power steering of the UAZ-31631 holds 1.3 liters.
8. Steering gear. The capacity is 250 ml. The volume of the brake mechanism is 0.6 l.
9. Window washer tank. Up to 5 liters of liquid are poured here.

The shock absorbers (0.3 l) and clutch drive (0.18 l) have the smallest capacity. The owner must be familiar with all the parameters of filling containers. The necessary information can be found in the user manual.

Characteristics of the UAZ 469 engine

It’s worth looking in more detail at gasoline consumption: With a reference consumption of 10.6 liters on the highway, the average gasoline consumption of the UAZ 469 is about 10.75/l. 100 km along the highway. And the maximum off-road gasoline consumption is approximately 17.25 liters. At 100 km.

DIY replacement instructions

The list of tools used for topping up is supplemented with a container for collecting waste liquid. Before starting work, the machine is brought into the inspection hole. Before changing the oil, warm up the car, using it for its intended purpose for at least 15 minutes. This promotes liquefaction and easy removal of waste. The replacement is done like this:

1. Place a container under the bottom to drain used oil from the transfer case. Using a wrench, unscrew the plug located in the lower part of the crankcase. Unscrewing the fill valve speeds up the waste removal process.
2. Wait for the liquid to drain and screw in the drain plug. Before installation, the part is cleaned of dirt.
3. Lubricant is injected using a syringe. Filling oil with a watering can will not work. A technical syringe copes with this task better.
4. Once the desired level is reached, the filling is stopped. The plug is returned to its place.

The work is completed by turning on the engine, which promotes uniform distribution of lubricant.

Features of changing gearbox oil

One of the types of UAZ Patriot gearbox repair is replacing transmission fluid

It is important to remember that when this procedure occurs, it is not recommended to mix oils of different classes. This will lead to a reduction in the life of the box

The algorithm for changing the oil in a Patriot gearbox looks like this:

1. The engine warms up to operating temperature.
2. The UAZ must be driven into the inspection hole.
3. An empty container is placed under the box where the waste liquid will drain.
4. Use a key to unscrew the filler plug.
5. Use a wrench to unscrew the drain plug.
6. As a rule, the plug has contamination that needs to be removed; in some cases it needs to be replaced.
7. New transmission oil should be added to the UAZ gearbox through the oil filler hole. In this case, it is worth using a refill syringe. It should be poured into the box in small portions.
8. The UAZ gearbox has a dipstick. With its help you can control the oil level in the gearbox. If there is a deficiency, liquid is added.

This procedure does not cause any difficulties. That is why many decide to implement it on their own. This helps save money.

How to do it?

First you need to unscrew the plug from the hole. It is worth noting that there are several of them. The first one, located in the middle of the box, is for the fill, and the one at the bottom is for draining the liquid. It is unscrewed, as on most domestic cars, using a hex key. Before doing this, you should prepare a container in advance where the old oil will be drained.

It can be made from an old canister by cutting off its side part. After draining the fluid, the gearbox (UAZ “Bukhanka” is no exception) undergoes a flushing process.

How much oil to pour into the axles and transfer case of the UAZ Patriot

First generation 3163, since 2005

UAZ Patriot is an updated version of the Simbir. After modernization, the car became more comfortable and easier to handle. In general, the car became more “civilian”, but still had disadvantages in comparison with foreign analogues. The SUV borrowed the body, Spicer-type axles and ZMZ engines from Simbir. Today, the top-end version of the Patriot is equipped with an upgraded ZMZ Pro with a capacity of 150 hp. s., aggregated with a six-speed automatic transmission from the BMW 3 Series. In addition, to increase reliability, the car is made from a large number of foreign components: a Takata-Petri AG steering wheel (Germany), a Sanden air conditioner (England), a Dymos gearbox and Dawnsco seats (Korea), a Delphi power steering (Italy), etc. .

• Transfer case oil: volume – 0.7 liters, tolerance and viscosity: API-GL-3-4, TSp-15K. TAP-15V, TAD-17I; SAE 75W-90
• Rear axle gearbox oil – 1.4 liters; front - 1.5 liters; tolerance and viscosity: API-GL-3-4, TSp-15K. TAP-15V, TAD-17I; SAE 75W-90

Let's sum it up

UAZ Patriot transmission units are designed to operate in aggressive operating conditions, and therefore are characterized by increased endurance. Despite this, their operational period directly depends on the owner’s compliance with the regulations for their maintenance. Irregular oil changes or completely ignoring them can cause vehicle failure, reducing its handling, maneuverability and safety on the road.

It is not difficult to carry out routine maintenance of axles, transfer cases and gearboxes at home, but it is advisable to replace the transmission oil in all components, which, on the one hand, will allow you not to get confused about the timing of re-replacement, and on the other hand, will extend the life of the car. And, most importantly, do not skimp on the quality of the lubricant; the operational period of components, assemblies and the vehicle as a whole depends on this.

Complexities of the Bay

Surely UAZ owners have encountered the problem of the impossibility of filling oil. To do this you need to try hard. Fortunately, motorists share tips, and the procedure becomes much simpler. Many drivers recommend using a long metal syringe with a curved rubber spout for this. Its capacity should be at least 300 milliliters. We also note that the gearbox requires the use of viscous oil, so it will be difficult to fill it in - you need to “syringe” it with force. This is especially noticeable in winter. Then the gear oil turns practically into jelly. To ease the effort, motorists recommend melting this “jelly,” that is, preheating it. Fortunately, this is not gasoline, so nothing will burn or explode - you can safely hold the syringe over a gas burner or burner. If there is no such syringe, and replacement time is running out, then you can use improvised methods. UAZ owners are rich in ideas, and everyone invents their own way. For example, you can use a thin tube and a plastic bottle to fill the oil. The car is jacked up and oil is poured by tilting the bottle. It is important to achieve maximum tightness of the connection (this means the place where the end of the hose touches the neck), otherwise the fluid will not overflow into the transmission, but onto the asphalt. The UAZ gearbox will quickly fail.

Others use a longer tube and run it from the transmission filler neck through the hood. Place a funnel on the top of the hose. This method is simpler than using a plastic bottle.
