The back gear on "Kalina" does not turn on: reasons and ways of troubleshooting

The car "Lada Kalina" is equipped with a mechanical box. It transmits the torque from the engine to the drive wheels. Motorists note the reliability of this transmission. But sometimes the back gear on the "Kalina" does not turn on. The reasons can be different. In most cases, they can be solved independently. In today's article, we'll look at the causes of back-up faults ("Lada Kalina" will be the object of the review) and methods for their elimination.

Butter

In the gearbox, as well as in the engine, there is oil. Its viscosity is more dense than motor. On domestic cars, the manufacturer recommends changing the fluid at least once every 60,000 kilometers. If the rear gear does not turn on at Lada Kalina, check the level of lubrication in the box. If the mileage of the car is more than 60 thousand, drain the old liquid and use a new one. It happens that the oil level disappears because of the sagging stuffing box or pierced gaskets. Identify the place of leakage and replace the sealing elements.

How to change oil

To do this you will need a viewing pit or flyover. Warm up the car before the operation. Transmission oil is very viscous, and at low temperatures it does not completely leave the box walls. Find the drain plug on the gearbox. Using a wrench, unscrew it and place a container for draining the used liquid. Within 20 minutes from the box will pour out all the oil. Next, tighten the plug with a key and find the filler cap. It is on the side. Oil is poured through the watering can or hose from the engine compartment (since the check point on the "Kalina" is located transversely). After replacement, start the engine and warm up the box again. After five minutes, remove the dipstick and top up the gear oil if necessary. The volume of the liquid should be 2200 milliliters. This applies to the old "Kalin" on the box from the "nine", and new, on the transmission 2181 with a cable drive. By the way, it breaks much less often than the first. In half the cases, this method can solve the problem.

Adjusting the wings

Often after its repair, the Kalina does not turn on the rear gear. The speed of squeezing the pedal does not matter. Together with her, the fifth transfer will be lost. To correct the malfunction, you must adjust the position of the wings. How to do it? It is necessary to find a yoke of the wings and weaken it.

Then the lever is moved to the desired position (the rear or fifth speed). The clamp is tightened. It is necessary to check the efficiency of the adjustment on the injected motor. If after that you still do not turn on the rear speed on the "Kalina", carry out the adjustment for the first gear. Move the lever of the box to the appropriate position, before loosening the bolt. Turn the wiper drive anti-clockwise until the lever restrains the reverse gear lock. By setting the depth of the linkage to the cardan shaft, you will resume the serviceability of the box.

Solenoids

This mechanism exists both on automatic and on mechanical transmissions. The solenoid feeds through the ring-switch (located on the transmission lever). When you pick it up, the item is triggered. The solenoid rod is drawn inward. The reverse gear is engaged.

Together with this, the end of the transmission on the gearbox is activated, and the reverse lights are activated. Why does not include the rear gear on the "Kalina". The cause can be in the burnt out solenoid fuse. It has the marking "F-21". Check the fuse box and replace the burnt element.

What if he's whole?

If the reverse is not activated (Lada Kalina), the reasons may be in another part. For diagnosis, you need to disassemble the box case. Under it there is a connector connected to the solenoid switch. We turn it off and connect the contacts directly. We check whether the rear speed has turned on. If not, remove the solenoid connector and measure the voltage in it. When the voltmeter shows values less than 12 V, there is a short circuit. You can also check with a warning lamp. Its power should be from 3 to 5 watts. If it does not burn, then the wires are burnt in the chain. Looking for more. Close the pins of the connector that goes down under the floor of the car. This can be done with a metal clip. Then turn on the reverse. If he turned on without problems, then the closure happened here. In the case of serviceability of the element, remove the connector from the solenoid. Using two pins and a tester, measure the voltage. The ends of the tester are applied to pins. In most cases, the breakage occurs because of a break in the strand and the oxidation of copper. Most often, the wire is rubbed at the location of the clamp on the pallet of the mechanical box. How to test it?

Remove the clamp chip and disconnect the connector that goes to the reverse lights. We take the tourniquet out, release it from the insulation and look at the wires. If they have traces of fusion or other deformations, replace them. Cut the damaged part with pliers and connect the other. It is desirable that they have the same diameter and cross-section. The method of connection is twisting. But for greater confidence you can use a soldering iron and heat shrinkage. Do not forget to insulate the cord and place it in the corrugation. It is important that it does not get moisture. So you reduce the risk of oxidation. The collar itself is changed to a new one. After repair, we connect this connector and check the serviceability of the box. If the solenoid is faulty, measure the resistance level. This figure is 2.2 ohms. In the event of an element failure, the transmission oil also changes. Thread and sealing elements are lubricated with sealant. Otherwise on the box there will be streaks.

Mechanical part

If the rear gear on the "Kalina" does not turn on, the reasons can be in the switching mechanism. The latter has a spring in its design. She often breaks down. If the part "falls" to the bottom of the box, it will not interfere with the switching of speeds. The driver can leave for so many years, not suspecting that the spring flew in the mechanism. But if it is stuck in the grooves, the rear gear will be unavoidable. Depending on the position of the part, the speed can be switched on periodically, or it does not work at all. In this case, you have to completely disassemble the gearbox and pull the jammed element out.

Solutions to the problem

After you pulled out the part, you have two ways out of the situation. The first - to buy a new spring (it is inexpensive, about 100 rubles) and install it. The second is the replacement of the gear selector entirely. It costs about one thousand rubles. Experienced motorists do not recommend changing parts in part. The spring is made of poor-quality material and very quickly fails. A reasonable solution is the purchase of the mechanism in the collection.

Releaser bearing

This element is very reliable. But do not exclude its breakdown. How to determine that the release bearing was out of action ? To do this, you need to squeeze the clutch on the engine and listen to the work of the box. If the characteristic sound (rustling) is amplified when the pedal is released, and the rear gear on the "Kalina" does not turn on, the reasons for the bearing. But not only this speed will be badly included. Often because of "squeeze out" the subsequent transfers badly work. They have to be switched on with gas permeation and double vyderm. It is worth the detail inexpensively, but to replace it you need to completely remove the box.

Conclusion

So, we found out the signs of the breakdown of the back gear of "Lada Kalina" and the ways of solving it. In most cases, the problem is eliminated by yourself. However, in the absence of experience or free time, you can contact the workshop.
