Replacing oil in the gearbox is carried out every 75,000 km of mileage or after 5 years of operation. There may also be unscheduled replacements caused by oil leakage from the box due to the leakage of the seals. In general, when driving, VAZ 2108 2109 21099 should be borne in mind that the metal protection of the engine crankcase and the gearbox case in this car is not. Therefore, if you are on a stone, a border, stump, in general, any obstacle rising above the surface of the road of centimeters to 20 and hit it with a gearbox - then it is provided to you.
The fact is that the body of the gearbox is cast iron, and when mechanically shredded it cracks. And through the resulting cracks runs away oil. Repair broken gearbox is not subject to repair only on parts. Therefore, it is more inactive when driving in the forest and in a field with high grass.
On vehicles VAZ 2108 2109 21099 are used served and not served gearboxes. The served gearbox is equipped with a dipstick, to control the oil level in it. In not served there is only a drain and bay hole. Accordingly, it is very problematic to control the oil level in it very problematic, and oil is on the very top, and for control they run by the right front wheel on the brick. When the right wheel on the brick, the oil level in the box from the sulfur tube becomes slightly higher. We unscrew the cork slightly - if the oil begins to flow, it means its level in order.
There is another way to control the oil level in the non-serviced gearbox VAZ 2108 2109 21099, but a little later. So, you have a need for a box. And again, as in the case of engine oil, we are faced with a question: what kind of oil to fill?
According to the operating instructions, it is necessary to fill transmission oils 80W-95, but in the same instruction it is negotiated that it is allowed to pour into a box and engine oil. When filling the engine oil in the gearbox VAZ 2108 2109 21099 there are two pluses:
1) Motor oil is cheaper than transmission
2) Motor oil in winter in the frost is less viscous (it is easier to switch transmission easier on the car).
Therefore, again, given that, for the most part VAZ 2109 - a budget car, the fill of the engine oil is preferable.
So, you first need to merge the old oil from the gearbox. If you change the oil in the summer, then everything is fine. If in winter, then it is better to drive a couple of kilometers before the replacement - so that the oil is more liquid. It is necessary to prepare the container where you will merge the old oil.
If you have an Estocade or pit in the garage, then the process of draining the oil will pass simply. If you need to lie under the machine on Earth, it is necessary to find a low bucket or pelvis to substitute for the drain hole of the gearbox.
We take the key to 17 and climb under the car, we first unscrew the plug hole (in order to provide air access), then we substitute the tank under the drain hole and unscrew the drain plug. There should be about three liters of oil if less, then you drove with a poorly blurred gearbox. When the oil completely stopped dragging, either a thin flowing flows for a long ride, tighten the drain plug.
Now in the gearbox of your VAZ 2109 you need to pour new oil. The manufacturer recommends this through the bay hole. Of course, in the VAZ 2109 with a serviced gearbox, it is easy to do: I got the dipstick, inserted a hole with a funnel, and flooded the oil. However, in the gearboxes without probe (not served) it is very hard to do this: the funnel is not inserted into this hole. If you build something like a hose, with a cut-off bottle screwed to it, then the fill process will be very long (although this is also a good option).
Therefore, the recommendation is as follows: pour oil through a pear speedometer drive hole. Pear - the usual large enema, capacity, the more, the better.
We unscrew the speedometer drive fastening nut and take it out.
We leave the drive to hang on the side (the main thing is not to smear it, and they ourselves sucking the new oil from the cutter into the pear, then the pear is bringing the speedometer drive to the hole and squeeze it into the box. It will take it out until the oil flows from the left-handed bay opening Gear. flowed - tighten the lateral bay hole.
Through the speedometer drive opening, it's perfectly clear what oil level is now in the box. This can be used with periodic control of the oil level in the box - removed the drive of the speedometer, looked at the level, put the speedometer drive. And absolutely no need to climb under the car. We will put the speedometer drive in place, clamp it with a nut.
All, in your gearbox is flooded with new oil.
