Repair of gearbox VAZ-2109 with your own hands

The car's gearbox serves to integrate torque on the wheels. But even it has its lifespan and needs restoration. Repair the gearbox VAZ-2109, many motorists spend their own hands, as the device and the design is quite simple.

Causes of malfunction and failure

During the operation of the vehicle, the gearbox occasionally breaks down. This is due to the fact that any node of the machine has its own resource. An important fact are spare parts, which also affect the service life. If you believe the manufacturer, the repair of the VAZ-2109 gearbox should be done once for 50,000 km.

Let's consider the main causes of failure of the gearbox of the car "Zhiguli-2109":

• Elements of the unit are heated during short-term operation. The first thing that indicates the heating of the gearbox is the gearbox knob. It transmits thermal energy, which can be felt with a touch of the hand. The gearbox itself is very hot. A sign can also be a breakdown of one of the gaskets that failed to withstand significant heating.
• Noise when the engine is running. When synchronizers fail or gears wear out, they start to buzz, which is audible even in the cab of the car. In most cases, rumble produces bearings, as well as a squeeze mechanism.
• Poor gearing. The first position is not included the first time, or you need to apply a lot of effort to ensure that the lever has hit the desired point.
• During the movement of the transmission, spontaneous shutdown. This indicates that the gears of the primary and secondary shaft are worn out and require replacement.

All these reasons can serve to the fact that the gearbox starts to fail and needs repair.

Choice of gearbox

If the gearbox 2109 is not repaired in time, it will be necessary to replace it. For this you need to know the catalog number of the spare part. It looks like this - 2109-1700010. This is the gearbox assembly, which must be installed in place of the old gearbox, if it is inoperative. Such repairs are carried out in the event of a crack or damage to the power unit unit.

Pricing policy at the checkpoint and details in different countries

The cost of nodes and parts in different CIS countries is different. Even on the territory of Russia closer to major cities (Moscow and St. Petersburg), the price will be higher than in other regions. Let's consider the basic price indicators for spare parts of the gearbox VAZ-2109 in the Russian Federation and Ukraine.

Of course, the price of components depends on the manufacturer, but the table has indicated the cost of parts for AvtoVAZ.

Cost of bulkheads and repairs

The cost of repairing the VAZ-2109 checkpoint on average in the Russian Federation is 12,500 rubles. It should be noted that in regions close to Moscow, it will be about 15 thousand rubles. In remote areas - about 11-12 thousand rubles. Thus, it becomes clear that the repair of the VAZ-2109 checkpoint (the price, in particular) will depend on the region where the reconstruction works are carried out.

In Ukraine, the average market cost of the bulkhead of the box, with its removal and installation, will be about 3,500 hryvnia, which in translation at the rate is much less than in Russia.

Tools and equipment

In order to repair the VAZ-2109 gearbox, certain skills will be required. And also for the execution of operations the following tools will be needed:

• Set of heads and keys from 8 to 24.
• Flat and cross-head screwdriver.
• The hammer is small and chiseled.
• The magnet is small.
• Sealant.
• Remover of stuffing boxes.

If nonstandard situations arise, you may need an additional tool that you can borrow from a neighbor in the garage.

Dismantling gearbox

Repair the gearbox on the VAZ-2109 with your own hands begins with the removal of the gearbox. It's worth remembering that this knot on the "nine" is removed below, so you need a pit or a lift. Consider the sequence of actions for dismantling the gearbox from the car:

• We remove the "terminal-minus".
• The ground wire is disconnected from the crankcase.
• Turn off the speedometer.
• The clutch fork must be disconnected.
• On the motor are mounted "hooks", the so-called "staples", which are hooked over the winch or telpher.
• The engine is raised together with the gearbox.
• The next step is turning off the reverse and draining the oil out of the box.
• Now you can disengage the rod from the select rod of the gear.
• Having unscrewed bolts of fastening, we divide ДВС and a check point.
• Further, drive shafts are disengaged from both sides.
• We disconnect and dismantle the starter.
• We take out the shaft from the clutch and dismantle the gearbox from the car.

Now you can carry out basic repairs of the gearbox VAZ-2109. And also major restoration works.

If the VAZ-2109 is doing repair manual gearbox with your own hands, then before this the gearbox must be disassembled. Consider how to do this:

• We clean the entire surface of the box from dirt. This can be done with a soft brush, as well as a cloth moistened with kerosene.
• We unscrew bolts of fastening of a back cover and we carry out dismantle.
• We include III or IV transfer. Fix the shafts and unscrew the fork of the V gear.
• We unscrew the nut on the primary and secondary shaft.
• Using a screwdriver, take out the synchronizer and then the clutch.
• We dismantle the gear shaft V from the secondary shaft.
• The driving gear 5 of the transmission is also removed from the input shaft.
• Now we dismantle the bearings. For this purpose, we first remove the locking rings.
• Having unscrewed the latches, we remove the balls with the help of a magnet.
• We dismantle the transaxle case.
• After unscrewing the bracket, remove the shift fork of the I-II gear.
• We remove the stem of the V gear from the gear and rotate it. Now you can dismantle it.
• Remove the fork and reverse gear.
• Now you can pull both shafts. It is worth noting that this is done simultaneously, so as not to damage other elements.
• Dismantle the gearshift mechanism.
• Press out the front and rear oil seals.
• Disconnect the speedometer drive.
• We disassemble the shafts. Consistently take out the gears, synchronizers and lock rings.
• When the gearbox is dismantled, it should be inspected for defects.

Troubleshooting

Before repairing the VAZ-2109 gearbox, it is necessary to determine the main faults:

1. We inspect all parts of the case. If there are cracks and chips, it is necessary to replace the damaged part.
2. After dismounting the bearings, it is necessary to inspect the seats for wear and tear. The same is done with the gland packing points.
3. Synchronizers, gears and forks are investigated for the purpose of working out.
4. We carefully study the shafts. If they have scratches, you need to replace the part.

Assembly and repair of gearbox

Assembly of the gearbox VAZ-2109 is carried out in reverse order to disassembly. After the gearbox is assembled, it must be filled with oil. For breaking-in it is possible to add a traditional liquid marked TAD-17. When the car travels 500-700 km, it is necessary to drain the run-in oil and fill it with a constant one. From its quality will depend on how many checkpoints will work after carrying out basic or major repairs.

It is worth remembering that when collecting, you must use new gaskets and sealant. Many motorists recommend not to change the repair of the gaskets, if they could be carefully removed. Professionals are advised to change in any case to exclude the probability of breakdown of the gasket.

For filling oil in the gearbox VAZ-2109 marking 75W-40, 80W-90 is used. The capacity of the box after repair is exactly 3 liters. It is recommended to fill the GL-4 or GL-4/5.
