How to remove the starter on a VAZ 2110, replacing the starter, retractor, bushings

It is no secret that it is impossible to start a car without a starter. Therefore, his condition should always be treated with increased attention. If it was not possible to save the element, then it is quite possible to carry out the repair yourself. It will be much cheaper than going to a service station.

First, study the VAZ 2110 starter from the photo, which will allow you to get a first idea about it. Don't worry if you've never even seen this element. This is not a hindrance to understanding the device.

It may have two problems - a complete breakdown that requires replacement, or it simply does not turn the engine. We will consider each issue separately in order to understand the causes and methods of eliminating the malfunction.

How to quickly remove the starter on a VAZ 2110 with your own hands

A starter is a unit that is used to start the engine.
Essentially, this is an electric motor that rotates the engine flywheel through a clutch until the flammable liquid ignites and the engine starts. There can be many reasons for replacing or repairing the starter:

• a grinding noise in the engine compartment when turning the ignition key to start (bendix malfunction or flywheel wear);
• clicks when turning the key (retractor relay);
• The engine is difficult to turn (rotor brushes are worn out).

Starter VAZ 2110

These are the main reasons; an electrician will tell you in more detail during disassembly and diagnostics. Basically, it can be repaired, but if reasons such as replacing the armature arise, then it is advisable to replace the entire starter assembly, but the problem arises: how to remove the starter on a VAZ 2110?

Starter relay (retractor)

The starter retractor relay is located on the starter itself and serves to move the bendix to the flywheel, and then engage with it. This relay often fails due to poor workmanship. It is quite easy to understand that the solenoid relay has failed; with such a breakdown, the starter will spin at idle, but the engine will not rotate, since the moving part of the drive (bendix) will not engage with the flywheel.

Replacement

To remove the VAZ 2110 starter, you need a pit (preferably), a key for 10, a key for 13, a key for 15, and a key for 8. It is advisable that the engine is cooled. We remove the negative terminal of the battery, remove the protection, if there is one, and use keys 8 and 10 to remove the tin cover for the gearbox protection. We remove the power wire plug from the starter; just pull it towards you. Using a 13 key, unscrew the power wire to the solenoid relay; it is advisable to move the wires to the side, no matter what gets in the way during dismantling. Using a 15 wrench, unscrew the two nuts securing the starter to the gearbox housing. We're filming.

After removal, it is necessary to check the condition of the bushings in the gearbox housing for wear; the armature shaft should fit in without play or jamming. In case of these defects, it is necessary to replace the bushings.

Starter malfunctions

Of course, the mechanism may stop working, and therefore experts identify several malfunctions here:

Bendix replacement

If the reason is wear of the solenoid relay or bendix of the VAZ 2110, you can carry out this work yourself. In order to remove the solenoid relay, unscrew the fastening of the power wire from the starter housing with a 13 key. Using a 8 key, unscrew the two bolts securing the solenoid relay to the starter housing, be careful, when unscrewing the bolts, there is a spring in the solenoid relay, which can cushion when removing hold with your hand. Next, remove the retractor relay piston from the rocker arm hook on the Bendix and install a new retractor relay in reverse order.

To replace the bendix, remove the solenoid relay, unscrew the two long bolts with a 10mm wrench on the back of the starter and disconnect the starter housing and its front part with the fork, bendix and rotor. Using a screwdriver, remove the plastic fork from the armature and remove the armature with the bendix from the front of the body. Remove the retaining ring from the armature tip and dismantle the bendix. Assembly is carried out in reverse order. When installing a new bendix, it is recommended to lubricate the splines with LITOL lubricant.

Doesn't it turn?

Device diagram

If the starter on an injection VAZ 2110 does not turn, there may be several reasons for this.

1. The culprit is the solenoid relay. If you insert the key, turn it, the instrument panel lights up, the fuel pump turns on, but when you turn it further, the panel goes out and the starter does not turn on, you should check the solenoid relay. Make sure there is voltage in it. Try closing the starter, turning off the alarm, which can also cause problems. If everything works separately, but in the end the starter does not turn on, then the reason is in the solenoid relay. It needs to be replaced with new ones and the problem will disappear.
2. Overrunning clutch does not work. You started a cold engine, drove a couple of tens of kilometers, stopped to get out for a couple of minutes, returned, and the starter clicks, but does not turn on your VAZ 2110. Only when the car cools down, you manage to start the engine. First of all, the overrunning clutch, or popularly Bendix, is to blame. Replace it with a geared analogue. Additionally, check the wires that go from the Bendix to the battery.
3. There are no contacts. The starter starts, but it is very difficult, making a lot of clicks. If the situation repeats regularly, be sure to check your contacts. The terminals are probably oxidized. Cleaning didn't work? Then check the ground contact with the car body and the starter contacts. For them, oxidation is a natural phenomenon. Another way is to ask a friend to turn the key in the ignition, and then hit the relay with a hard object a couple of times. If the car starts, then the closing contacts are simply stuck. But here it is better to completely replace all the relays than to repair and disassemble the unit.
4. The problem is in the immobilizer. It is not uncommon for the starter activation circuit on the injection VAZ 2110 to be disrupted due to the immobilizer. The engine may suddenly stall, the starter stops turning, and it is not possible to start it even with a push. The terminals are clean and the battery is charged. If the immobilizer is turned on, this may be the cause. Due to the protection being triggered, the engine does not respond. You will no longer be able to start the car, so call a tow truck and go to the nearest service station.
5. Problematic injector. We have examined almost all starter problems characteristic of a carburetor engine. But today the “tens” are injection ones. They don’t really like low-quality fuel, which VAZ 2110 owners so often like to refuel with. Therefore, the starter may not work for the simple reason that the injector is clogged or dirty. By performing a flush, you will eliminate the problem.

Replacing bushings

If you need to replace the bushings, there are two of them, in the gearbox housing and in the lower part of the starter. In the starter housing it can be changed without problems, but in the gearbox housing it is problematic to change it without a special tool (riber); this procedure is recommended to be done at a service station by a specialist.

After repair, it is recommended to check it on site before installation, with the power terminals from the battery.

Installation is carried out in reverse order. The nuts for 13 fastening the terminals must be tightened without much force, since the terminals are copper and if tightened too tightly, the threads can be damaged.

How to disassemble and repair the VAZ 2110 starter?

It is impossible to troubleshoot the starter without removing and disassembling it, so it has to be removed. The diagram of this procedure is given below: remove the battery terminals; We disconnect the cable connector from the relay; remove the wire marked “plus”; disconnect the starter from the engine by unscrewing the mounting nuts.

The mechanism has been dismantled, now you can begin disassembling it by performing the following steps:

• Unscrew the nut on the relay and disconnect the traction device from the contact bolt;
• remove the relay by unscrewing the two clamps;
• remove the relay armature from the lever (you need to slightly lift it up);
• remove the starter cover (it is necessary to remove the studs).

After all these operations, it becomes possible to remove the mechanism cover: first, it is removed as an assembly with the drive and gearbox on the drive side, and then with the brushes and their holder on the commutator side. Now you can remove the gear from the anchor shaft and take out the anchor, and then dismantle the gearbox gears. If they have defects, the gears need to be replaced (it is because of them that the starter often does not turn).

Next, with some force, we press on the drive gear and remove the gearbox from the cover. After this, remove the support from the lever (it is equipped with a sealing element) and check it for hardening and deformation. Very often the starter does not turn because of such little things. Just install another gasket, and you will forget about the inoperability of the starting system for a long time.

At the next stage of disassembly, using a mandrel, remove the restrictive ring from the retaining ring, then remove the drive, the lever ring and the lever itself with the washer and driver, as well as the lever spring. Now you can remove the drive shaft support, gear, and seal ring. Replacing the last of these parts is necessary in cases where it has lost its elastic characteristics (or has obvious signs of deformation).

Possible starter failures

There can be a large number of starter breakdowns, but most often they are all of the same type. Below are all the most common starter failures.

Brush wear

Starter brushes are a copper-graphite part that conducts electric current. The brushes are in direct contact with the starter armature and rub against its commutator, conducting electric current. During long-term use, brushes become unusable due to friction and must be replaced. This breakdown is not expensive or complicated; you just need to remove the starter and replace the brushes.

Bendix wedge

The Bendix is ​​directly connected to the flywheel and quite often, wear appears inside it or on its gears due to high load, which makes it impossible to start the car from the starter. By design, Bendix is ​​an overrunning clutch that rotates freely in one direction and is locked when rotating in the other direction. This part is sold separately and can be replaced as soon as possible.

Gearbox failure

The VAZ 2110 starter is geared. This modification allows you to reduce the load on the battery and rotate the engine crankshaft much easier and faster due to the additional ratios. Quite often, wear appears on the gears, which can lead to jamming or even breakdown of the entire gearbox.

Winding break

Since large currents flow in the starter, the winding in it is quite powerful and can withstand large currents, but sometimes a large cross-section of wires is not able to preserve the winding and it burns out, rendering the starter unusable. Such a breakdown can be repaired by replacing the rotor.

Solenoid relay

The retractor is an electromagnetic part that is retracted under the action of an electromagnetic force, driving the bendix inward and engaging it with the flywheel. Inside the relay structure there is a regular coil, which quite often burns out and damages the starter.

Almost all starter failures can be repaired by replacing the broken part with a new one.
