The design of starters on the VAZ 2109 has fairly good reliability indicators. But with use and over time, they still fail.
Appearance of the device
Design and operating principle
To understand the features of the repair, you must first study the design of the starter and understand how it works for the benefit of your car.
Let's start with the design. It includes four main nodes.
| Knot | Peculiarities |
| Electric motor | It transmits direct current through four brushes |
| Freewheel with gear | A clutch or bendix drives the flywheel of your car's engine. |
| Traction relay | Serves to extend the bendix with gear when turning on the electrical appliance |
| Bushings | Ensure easy rotation of the clutch, rotor, and gear. One bushing is located inside the starter, and the second is in the clutch housing. |
Device diagram
Having familiarized yourself with the starter diagram, you can discuss the principle of its operation.
The operating principle is to convert an electrical signal into the rotational movement of a drive gear. Current is transmitted through the brushes to the poles of the electric motor. At the same time, the clutch extends and the gear is connected to the flywheel ring. To start the engine you need a quick but easy rotation of the starter. When the engine starts, the clutch returns to its original position.
Gearbox or rotary starter for VAZ 2109?
Today I will tell you with my own example about the differences between gearbox and rotary starters! For a long time I suffered with this rotary starter, installed back in 1998 in Togliatti on the AvtoVAZ assembly line. Owners' suffering, as a rule, begins under certain circumstances)) For example, when the battery is several years old and there are problems with the power supply or ignition system. That is, when the carburetor overflows or there is a slight malfunction of the distributor, when it’s already difficult to start (and you have to go to work), then our battery comes to the rescue in getting through the day =) We tried to start. There was just a little bit left and should have been “grabbed”, but the battery died =( And then psychosis, hatred of everything in the world, despair. Everyone knows this!
This is my old starter. Rotary. Renovated 5 times already.
I got a car from my dad relatively recently. Previously, I could not influence her fate and for some reason I was not interested in how and what was going on with dad. He lived in Budennovsk, I lived in Moscow. But now...
While closely studying our and non-our automobile industry, I learned that modern cars have gear starters. Well, I bought myself a brand new shiny ZIT starter.
Well, now about the differences.
— What can I say about the stock starter that was installed in the VAZ 2109 in those years. Well, for starters, it's rotary.
