DIY VAZ-2109 gearbox repair

The car's gearbox is used to integrate the torque into the wheels. But even it has its own life and requires restoration. Repair of the VAZ-2109 checkpoint is carried out by many motorists with their own hands, since the device and design are quite simple.

Causes of malfunction and failure

During operation of the car, the gearbox periodically fails. This is due to the fact that any machine node has its own resource. An important fact is the spare parts, which also affect the service life. If you believe the manufacturer, the repair of the VAZ-2109 checkpoint should be carried out once per 50,000 km.

Consider the main reasons for the failure of the gearbox of the car "Lada-2109":

• Elements of the unit are heated during short-term operation. The first thing that indicates gearbox heating is the gear knob. It transfers thermal energy, which can be felt with the touch of a hand. The gearbox itself is very hot. A sign may also be a breakdown of one of the gaskets that could not withstand significant heating.
• Noise during engine operation. When synchronizers fail or gears wear out, they begin to buzz, which is heard even in the car cabin. In most cases, the hum is produced by bearings, as well as the release mechanism.
• Bad gear shifting. The first position is not included the first time, or you need to make a lot of effort so that the lever hits the desired point.
• When driving, the gears spontaneously turn off. This indicates that the gears of the primary and secondary shaft are worn out and require replacement.

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

Gearbox selection

If the gearbox 2109 is not repaired in time, it will need to be replaced. To do this, you need to know the spare part number. It looks like this - 2109-1700010. This is the gearbox assembly, which must be installed instead 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 block.

PPC pricing policy and details in different countries

The cost of components and parts in different CIS countries is different. Even in the territory of the Russian Federation, closer to large cities (Moscow and St. Petersburg), the price will be higher than in other regions. Consider the main price indicators for spare parts of the VAZ-2109 gearbox in the Russian Federation and Ukraine.

Of course, the price of components depends on the manufacturer, but the cost of parts manufactured by AvtoVAZ was indicated in the table.

Bulkhead and repair cost

The cost of repairing a VAZ-2109 checkpoint on average in the Russian Federation is 12,500 rubles. It is worth noting that in the 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 (price, in particular) will depend on the region where the restoration work is being carried out.

In Ukraine, the average market cost of a box overhaul, with its removal and installation, will be about 3,500 hryvnias, which in translation at the exchange rate is much less than in the Russian Federation.

Instrumentation and equipment

In order to repair the VAZ-2109 checkpoint, certain skills will be required. And also for performing operations you will need the following tools:

• A set of heads and keys from 8 to 24.
• Flat and Phillips screwdriver.
• Small hammer and chisel.
• The magnet is small.
• Sealant.
• Oil seal puller.

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

Gearbox disassembly

Do-it-yourself gearbox repair on a VAZ-2109 begins with the removal of the gearbox. It is worth remembering that this node on the "nine" is removed at the bottom, so you need a pit or a lift. Consider the sequence of actions for dismantling the gearbox from the car:

• Remove the "terminal minus."
• The ground wire is disconnected from the crankcase.
• Turn off the speedometer.
• The clutch fork must be disconnected.
• “Hooks” are mounted on the motor, the so-called “brackets”, which are hooked onto a winch or hoist.
• The engine with the gearbox rises.
• The next step is to turn off the reverse and drain the oil from the box.
• Now you can disconnect the traction from the gear selection rod.
• Unscrewing the mounting bolts, we separate the engine and gearbox.
• Further, the drive shafts are disconnected from both sides.
• Disconnect and dismantle the starter.
• We take the shaft out of the clutch and remove the gearbox from the car.

Now you can carry out basic repairs of the VAZ-2109 checkpoint. As well as capital restoration work.

If we do the repair of the checkpoint on our VAZ-2109 with our own hands, then before that 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 rag dampened with kerosene.
• We unscrew the bolts of the rear cover and carry out the dismantling.
• We include III or IV gear. We fix the shafts and unscrew the fork of the V gear.
• We unscrew the nut on the primary and secondary shaft.
• Using a screwdriver, we take out the synchronizer, and then the clutch.
• Dismantle the V gear gear from the secondary shaft.
• The drive gear 5 of the transmission is also removed from the input shaft.
• Now dismantle the bearings. To do this, first remove the snap rings.
• Having unscrewed the locks, with the help of a magnet we dismantle the balls.
• Dismantle the gearbox housing.
• Unscrewing the mount, remove the shift fork I-II gear.
• The transmission rod V is disengaged and rotated. Now you can dismantle it.
• Remove the fork and reverse gear.
• Now you can pull out both shafts. It is worth paying attention that this is done simultaneously, so as not to damage other elements.
• Dismantle the gearshift mechanism.
• We press out the front and rear oil seals.
• Disconnect the speedometer drive.
• We disassemble the shafts. Sequentially remove the gears, synchronizers and snap rings.
• When the gearbox is disassembled, it should be examined for defects.

Troubleshooting

Before starting repair of the VAZ-2109 checkpoint, it is necessary to determine the main malfunctions:

1. We inspect all parts of the body. If there are cracks or chips, replace the damaged part.
2. After dismantling the bearings, it is necessary to inspect the seats for output and wear. We do the same with the installation locations of the seals.
3. Examines synchronizers, gears and forks for production.
4. We carefully study the shafts. If they are scratched, a replacement part is necessary.

Gearbox assembly and repair

The assembly of the VAZ-2109 checkpoint is carried out in the reverse order to disassembly. After the gearbox is assembled, it is necessary to add oil to it. For break-in, you can add a traditional fluid marked TAD-17. When the car travels 500-700 km, it is necessary to drain the break-in oil and pour constant. From its quality will depend on how much the checkpoint will work after a basic or major overhaul.

It is worth remembering that when collecting it is necessary to use new gaskets and sealant. Many motorists recommend not changing the repair kit of the gaskets if they were able to be carefully removed. Professionals advise changing in any case, in order to exclude the possibility of breakdown of the gasket.

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