I bought a used Oka, a novice car enthusiast, I want to learn how to repair it myself.
The problem is this: the bushing on the starter is constantly falling apart, I change it every two days (they say that on other cars they press it, but on the Oka it fits in easily). They suggested purchasing a new starter, but I want to understand the problem.

I wonder how many times you changed them. Think about the hint. It was not in vain that they suggested a new starter.

. The bushing on the starter or the bushing in the clutch housing “falls out”.
. What kind of noises, knocks, crackling sounds when starting the engine?

The bushing “with a skirt” into which the starter is inserted, there are no knocks, crackles, or noises. When you start it, it feels like the battery is dead.
You can buy a new one, but suddenly it’s not the problem, and you don’t want to throw away 2.5 rubles.

. The rotor clings to the stator due to the bushing.
. however, you also need to look at the clutch housing. Maybe the hole for the bushing is “gouged out”. then you need to either change the clutch housing or come up with a “screw-in” for the bushing. Problem.
. If the housing is intact, then you need to look at the starter itself. The battery and generator are in good working order.

How can you check whether the hole for the bushing is “broken”, maybe some signs or visually? and is it still possible to turn a bushing out of bronze or copper, or will it still be even worse?

. rapid wear of the shaft at the anchor. The bushing should probably be metal-ceramic.

There was such a problem, the solution was this: measure the seat for the bushing in the clutch housing by removing the starter - obviously, if there are no remains of the bronze bushing there, you can by selecting gauges (I used drill shanks) - the diameter is somewhere around 10-12 mm, and by measuring the length ( depth) grind out a bronze or copper bushing (it has a collar, I don’t remember exactly, about 13-15mm in diameter, the length of the collar is 2mm), put it on the starter shank and put the starter in place. After such a replacement, the problem disappeared, and if it doesn’t help, immediately change the starter (they are not in short supply)

Try connecting the removed starter to the battery - if it turns easily and with normal noise - OK, rattles and sticks - replace it!

. Gleb, you are saying something wrong. With the starter removed, you cannot try - one end of the rotor will be unfixed. In any case, the rotor will touch the stator.

Sorry, it’s quite possible, then for diagnosis I suggest turning on the starter installed in place (after replacing the bushing) directly, bypassing the solenoid relay, for 10-20 seconds and assess the situation - noise, jamming, tight rotation, current consumption, etc.

Thank you very much, we will experiment). The factory bushing is copper-graphite, if you turn it out of bronze or copper, you can completely ruin the inlet hole (again, according to rumors), is this true?

How to replace the starter bushing?
Recently I was treated for such a problem. The starter didn't turn well. Especially on the first start after an overnight stay. I looked at the bushing, poked the rotor there, Polpation showed that everything was fine. But still I decided to replace it and pulled it out with a tap. The tap plays the role of a puller. It turned out that the bushing was worn unevenly. The hole looks a little like an oval, but when inserting the rotor it is not noticeable. Bushings are available for sale, but as a rule they are repair size. I had to sharpen the outside a little. I sharpened it with a flat velvet file, holding the sleeve in an electric drill.. It is necessary that the sleeve fit tightly into the socket. Getting the bushing into the crankcase is difficult IMHO. Since she is focused. When I pressed the bushing in, the starter shaft did not fit into the bushing.
