What oil pour into differential. Do I need to change the oil in differential and box? Features of oil replacement in the front and rear differential

And, again about replacing oils. Such an actual topic.
Of course you need! But with the mind.

It is required to monitor the level and its condition, but to change, only in the case of strong drills and, of course, when the oil level becomes below the norm. Take the oil (if you definitely do not know all oil parameters) in no case can only change, otherwise it is possible to fold oils of different bases and additives.

If water got into the oil, because the flood is not uncommon, in this case it is necessary to replace it.

Very often unjustified oil replacement in these aggregates, delivers maximum troubles and inconveniences. For example, in Judza Bighorn in the box poured ordinary motor oilbut there were cases when the owners of habit were flooded there transmission oil. After that speed switched tight. IN rear Differential the same car is poured special oil LSD and if it is replaced by mistake on another, even most expensive, then a headache from finding the causes of bad work of the rear axle is provided to you. The rear differential lock mechanism in this case will not work normally. There will be various noise and screens, especially on turns. Further, it is possible to fail or, as a result, can break the automatic. Therefore, if you still want to change the oil, then it is necessary to drain it in pure containers, suddenly it is useful (at the same time check if there was no water or mechanical impurities). It is also desirable to determine before replacing the oil at least by smell, which was flooded in one or another unit. Conventional transmission oil has an unforgettable sulfurous smell and distinguish it from motor or dextro quite forces even beginners. So if the oil that you merged with the unit is transparent and does not have at the bottom of the sediment, chips or water, pour it back. The only thing that can advise-add to the transmission oil is an additive in order to improve lubricating characteristics between the intervals of oil replacement and extend the time of its optimal work. So you will find calm and confidence in your car. As well as save certain funds that you can spend on your four-wheeled friend.

As for the front-wheel drive passenger carsTheir differentials are mostly lubricated by the dextron, which falls from the joint with the machine with the machine or if there are special holes for its fill (on cars old modifications is poured through these additional holes). Merifying oil from such differentials or mechanical boxes, also focus on the smell and color of the fused oil. Consight dextro, transmission sAE oil 80-90 and ordinary engine oil is difficult. The main thing is to check the condition and oil level in the transmission units. After all, degradation (loss of operational properties) of transmission oil leads to damage to the parts. And this is the main reason for the breakdown of the transmission.

BG Products, Inc has developed special additives for transmission oil, improving it operational properties and protecting components of differentials and transmissions:

1. 1. Transmission oil additiveBG.Multi.— Gear.Concentrate.№ 325

Thermally stable, high-tech additive into transmission oil, designed specifically for all types of standard mechanical transmissions and is suitable for use in all types of dispensing boxes.

Perfect for cars with Full-Time 4 WD system. BG LSII components are lubricated parts, reduce the noise in bridges, and also increase the action of additives in the transmission lubricant.

To improve the quality of GL-5 transmission oil for the possibility of maintaining a limited slip differential, use one bank (177 ml) for differentials of up to 1.7 liters. For large volumes, increase consumption by 10%. Run the car, try to make some sharp turns left and right. Noise and rattling should disappear after the first few turns.

Thanks to special components, BG 328:

- eliminates noise and vibrations in differentials and distribution boxes of all-wheel drive cars

- Promotes more smooth transmission

- reduces system noise in work

I would also like to mention the line of transmission oils developed by BG Products, Inc. Since they really deserve attention. And, if it all came to replace the transmission oil, I would advise the American BG products, which took a deserved niche in the global market, but, to my regret, I still have so little well-known with us (in particular - in Vladivostok). So:

Do I need to change the oil in differential and box?

Do you use additives to oil

What is this service?

The differential uses a special type of oil. The car has a special gear mechanism connecting two semi-axes. This mechanism is responsible for converting the engine power and for its transmission to the wheels, it allows the wheels to rotate with different speeds of rotation. This node is called differential and for its proper functioning requires lubrication. Differential oil provides lubrication and cooling of the car differential. It prevents the "dry" friction of the metal surfaces of the gear and prevents overheating.

For stable work All car mechanisms they need constant care. - not very frequent, but extremely important procedure. Despite the rather complicated design of the differential, the replacement of liquids in it is quite simple.

When to make a replacement?

There is no unambiguous answer to this question, it all depends on the operating conditions and the specific machine model. Experts expressly revealed that, at regular work, this procedure is necessary on average every 40-60 thousand km of mileage.

If the car is used very intensively, then with time in the gearbox crankcase, slow oxidation and decomposition of the oiled oil occurs. This is due to severe heating and air from entering the sealer system. Differential nodes are also affected due to reducing the viscosity of the oil, which inevitably occurs during operation.

Anyway replacing oil in differential It is carried out at least once every two years. Usually car owners make this operation in the complex with others during the preparation for the winter / summer season.

How is the oil change in the rear gearbox?

To do this you need looking Yama or overpass. To begin with a visual inspection and cleaning. If the cutter gearbox is very dirty, then it is pre-washed. This is done with the engine on. After washing, the new oil is filled with a syringe or a special device.

Make a replacement of oil in the gearbox yourself quite simple, for this you need minimal knowledge and a little time. If the latter is not enough, and the device machine for you is "deaf forest", then it is better to contact a specialist who will make all operations quickly, efficiently and at an affordable price. It is worth paying attention to the spent gases, you may need to spend.

Keep in mind

On parts of cars differential installed in front bridge, On other cars - in the rear bridge. Some cars use synthetic transmission oil.

• Try to avoid excessive loads and operation of the machine in extreme conditions - it significantly increases the frequency maintenance.
• Do not save on oil! Its replacement is made quite rarely and is inexpensive, at the same time, poor-quality liquid can cause a malfunction and expensive repair.
• When servicing a car strictly follow all manufacturer's recommendations set forth in the "Operation Manual".

In this article we will try to answer the questions regarding the liquids for the gearbox, which is the most important detail of the car, because it will not go without it. Why it is important to know, because with the wrong choice of fluid, corrosion will simply eat all the gear elements and on this everything is to replace the box.

Everyone knows that in the engine we will enlighten that regularly every 10 thousand km, but what about the transmia.

How to choose the right oil into the mechanics - the difference between GL4 from GL5

Unlike motor, transmission more viscous oil, which is used to lubricate gearbox gears. In the passenger trucksIt often takes to be a MCPP, with two differentials, and in some cases even 4wd come across.

The most commonly encountered the following transmission viscosity, 80W-90 and with increased demands and additives, which will withstand any loads on bridges and the box.

Usually at the end of the book there is an alphabetic pointer. Look at the words "Fluids (Fluid)", "Capacity" or "Technical Specifications".

In this section, pay attention to the category of MCPP.

For example, in the 4WD Mazda CX-9, 2015 guide, there are two varieties that are used in this car.

Therefore, choosing a product for Mazda, pay attention to the label of banks, and as shown in the figure below the oil corresponds to the standard, which is very important and

How often should I change the oil - the change interval

For normal driving conditions, some car manufacturers recommend changing transmission oil every 90000-100000 km, while others advise simply to follow the condition of the oil, and change it as needed.

Ford goes even further, for some models under normal operating conditions, it does not obliges to change the transmission oil on the rear axle and on the power selection (it is a handout), motivating the fact that they are blurred almost life.

Nevertheless, we found many differences between technical experts.

Replacing Oil in Differential - Bridges

Many are offered to merge transmission oil at least every 100,000 km. Generally, mineral oil It is necessary to change more often, while synthetic more lively.

Transmission oil should always be replaced if water got into the composition. For accurate recommendations for your car, check the maintenance schedule. If your mechanic found oil leakage in gears, especially if from differential or dispensing boxThe item should be restored as soon as possible.

After completing the repair, I think it will not be superfluous to change the oil at the same time.

If you forget, the date or on what mileage was the bridges for the last time you can ask your mechanic to check the gear oil level.

In some cars, there is a second probe, to check the oil level in a manual gearbox (for example, there is such Subaru Forester.). If the probe is not, then the oil level and its state can be checked through the bay hole.

Usually, mechanical box Gears or rear differential has two plugs: one to bring transmission oil (through bay cork), and the other for plum ( drain plug).

Features of oil replacement in the front and rear differential

In many cars, the mechanic can remove the filler plug and check the level and condition of the oil through the bay hole. As a rule, the transmission oil should be on the same level with the filling hole. If below, it will be necessary to add.

If, when visual inspectionIt looks like something between dirt and fuel oil is the presence of metal particles, then you need a replacement.

In many vehiclesThe drain plug has a magnet attached to it.

Whenever cream and fill go, the magnet must be cleaned of metal chips before the installation itself.

Replacing the transmission oil in the car service is not particularly expensive, somewhere around 4000-5000 rubles, plus 7500 for differentials.

As with the gearbox, the bridges require the same special attention and right choice, for example, if pour oil intended for the front differential in Honda CR-VThis can lead to a grinding in turns, which will reflect on the ride.

Honda recommends using a special branded fluidwhich can be purchased only at the Honda dealer. If the car has an elevated friction differential (LSD), then it also requires a special product. If ordinary transmission oil is used in high-friction differentials, then over time it can lead to noise and stacks when turning.

Usually, it is necessary that the LS 75W140 is required, which we mentioned above are required, it can stand very serious loads, and parts will always be in the lubricant you need, so that there are no noise or a grinding, no knock.

Suppose we are talking about standard gear differentials. When in differential is very light oilThe weekend cups will be very easy to rotate in opposite directions (differential property). When the oil is very viscous, the outlet cups will rotate with greater resistance. It becomes important when one side of the differential becomes unloaded, i.e. When one wheel loses the clutch with the road.

This is most important, but it is not limited to, in case of turns. During turn, the external wheels should rotate faster, as they pass a greater path than internal wheels. Rear wheels are fixed directly, so the easiest operation of the differential is more important on the front wheels. The front wheels are rotated at the angle of rotation radius and the inner wheel turns the cooler than the external, so that you need a smaller impact resistance in front.

Rear, the lighter oil, the smaller power is fed to one wheel if the other rises or loses the clutch with the road. The more viscous oil, the high power It is fed to one wheel if the other loses the clutch with the road. This is most important during the turn, since the inner rear wheel usually tends to unload. If too much power is fed to the outer rear wheel when it happens, then the rear axis enters.

It is desirable in front that both front wheels pull buggy around turn. While turning, the weight of the chassis strive to move to the external front wheel. It is desirable that the front axle pulls well, even if the inner front wheel is unloaded. Front, the more viscous oil, the better pulls the external front wheel, even if the inner front wheel is unloaded. It provides a faster passage of turns with acceleration, but to a certain point. Too viscous oil can cause buggy pushing (insufficient turning) if the clutch with an expensive is insufficient.

What for the central differential? For the most part, the same idea. The lighter oil, the less power to any end of the buggy. The more viscous oil, the greater the power on both ends of the buggy. It is very important to maintain buggy stability. If the central differential contains light oil and one wheel at one of the ends of the buggy loses the clutch, then the power is lost on the other end of the buggy. This instantly slows down the buggy and allows the wheel that lost the clutch, restore it. Viscous oil allows you to save power on the opposite side of the suspended wheel.

For the most part, the rear wheels lose the grip more often than the front. It is desirable that the rear differential is very easy to, when one wheel becomes free, the other stopped pulling, and Buggy did not spin around. This allows the suspension wheel to restore the clutch. It is desirable that the wheel having a clutch continued to pull when the other loses the clutch. All this leads us to the basic starting point: oil 3000/5000/1000 WT in the differentials of P / C / s.

If there is a good clutch with the road, then you can tighten differentials, such as 5000/5000/1000 or even 5000/7000/1000. If the surface is loose and there is no good clutch, then it is better to soften differentials. For example, 3000/3000/1000 or so. This is a general setting for standard differentials. Torsen and Spider Differentials work somewhat differently. But that is another story.
