A strip of foil was sufficient to repair the eccentric sander

I talked about this grinder earlier. She has served me for more than half a year and generally suits me.

Recently, I noticed that the efficiency of her work has dropped somewhat. The plate at the grinder began to stop during operation, only vibration remained without rotation.

Moreover, at idle, with the rotary knob positioned approximately in the middle, the cymbal simply stopped.

In other positions of the regulator, the cymbal rotated, but easily stopped by hand.

I had suspicions why this was happening, but I had to make sure and fix the problem.

To do this, he unscrewed the sole and removed the eccentric block.

Before removing the sole, I idled a little. This was enough to warm up the bearing assembly.

The central bushing came out of the bearing without effort, thereby confirming my suspicions: it was turning only vibration was transmitted in the bearing and on the sole, and from friction when turning the bearing heated up.

I chose a very simple solution.

I cut off a strip of aluminum foil and screwed it onto the center sleeve.

Then I installed the sleeve in the bearing and assembled the machine.

After such a simple repair, the sole of the grinder began to spin up normally.

It was possible to stop it only at the lowest speeds, and then with some effort.

And then I checked how it works, and in half a minute I sanded one side of the bar.

For more clarity, I suggest watching the video.
