And what kind of grease do you need to lubricate the gearbox and gears with?

Dug up on the internet old: * Reducers of angle grinders, circular saws, brushcutter - NLGI 0 - semi-fluid. True, it is impossible to find or a large package. Therefore, you still have to bodyage. And in the video, the blue one is most likely Mobile 222 or the so-called. Oregon. But they are thick, NLGI 2.

This is THAT through the ass. Sucks! MINUS!

Hello, what kind of grinder model?

Apart from replacing the cable and washing the case, the sense of such TO is 0 point tenths. Do not add lubricant to the gearbox, but completely change it along with dirt and wear products. And the 158 is not suitable here in its pure form, it is too thick, hence the heating of the gearbox, it is necessary to badge it, for example, with a negro. Have you looked at the brushes, and what is the condition of the collector, especially if the brushes have uneven wear? How do the bearings feel? If we are to serve, then disassemble completely and look at all the nodes, and such a "THAT" is just on from. bang, to calm the soul

Perhaps you are right, thanks for the tip, next time I will.

Vitaly Krivtsov: Bored with their moronic ads

Lilit Lilit: Good afternoon, tell me the exact name of the melody that plays the very first, I follow the link so there are thousands of melodies, to be honest, I listened even more)))) Thank you

Video (click to play).

Kot 345: Put the disc incorrectly. You need a picture inward, then it will never jam. On the disc on the bore diameter on the side of the picture, there is a tin washer that prevents jamming.

Ivan Ukrainets: It's cheaper to buy a new grinder.

Ambulance Panties: the same grinder burned out the spiral (made by a ring) wire that goes to the brush. From which wire can you make a replacement?

Alexandr Eremeev: I have exactly the same model. Suddenly she died, stopped working altogether. Analysis showed that the speed controller board burned out (the board was clogged with metal dust and the elements were short-circuited). If you supply 220V directly to the engine (bypassing the speed controller), then the grinder works. Who knows where to get the circuit diagram of the speed controller? There are only 10-15 elements. I didn’t find it on the Internet (maybe I didn’t look for it well). the model is painfully old.

Alexander Tsygankov: Repair is creditable! But was it worth how much for the money from the new one? new gears, bearings, housing, brushes

Alexandr Sobol: bearing numbers would show ((

Bat: I think it is worth putting less lubricant in the gearbox, an excessive amount is not good, by the way, what kind of lubricant?

TheAlbrus: The video is good. I had such a problem, when working with a grinder it hits, I changed two bearings + on the rator 1 more and instead of a sleeve I put a needle bearing, but I noticed that there is a small backlash in the needle bearing. Is it possible that because of this backlash during operation beats?

johnpk77: It was necessary to bring the tool to such a state

Pitr Smolin: Damn, but how to pull the rotor out of the gearbox did not show, but this is exactly what I needed

Sergey Alexandrovich Leonchik: too much grease, it will burn out soon

sluge1: the screws had to be planted on the sealant

Alexey Bakum: There was also a problem when removing the rotor. It turns out a couple of mm and no further. 1 I decided to knock out with the bearing, it did not work (then I realized why, from the inside, the bearing was pressed by a plate with three screws). 2 Then I decided to break the bearing from the side of the gearbox - it also did not work. 3 Then I noticed "Rolling" on the edge of the shaft under the bearing and decided to hit the gearbox housing from the side that is attached to the grinder body. I held the rotor with my hand and beat it with a hammer. Five hits and the shaft took off. It would be possible to remove this edge, but the file does not take you can't crawl) or with a drill (but it's not there) And the reason is that the small gear, when destroyed, flared the shaft at the very edge. Maybe a tenth of a millimeter, but this “rolling did not allow the shaft to pass.
Yes, model 180T. I still change the gearbox housing, so I beat it without fear of breaking it, although it didn’t damage it.

DarkSoul: Nice video, but the moment of how to remove the rotor is missed. I'm just trying to do this, but alas, it turns out to be difficult. Do you have any practical advice on how to do this?

Denis Akhmetzyanov: Thank you for the video! I have 180dv, a small gear cracked, I did not find a suitable one in stores. Where did you buy it?

Dmitry Zarva: Not a bad Bulgarian but. the worst place is a small gear, during 2 years at work I went through the gearbox about 8 times. And another inconvenient place is its handle, and the engine is excellent!

ANDREY IGOREVICH: everything is exactly like mine, only now what for did you change the gearbox housing if you did not install the spindle fixation and left it with silicone, it was expensive, I brewed it with argon. And how did you manage to disassemble and assemble the rear bearing in the video, it's somehow not visible?
