In the absence of a specialized puller, you have to tweak in every possible way during the dismantling of bearings. Sometimes work "on the knee" ends with the destruction of the bearing or deformation of the shaft, from which it gets lost.
To avoid such risks, it is worth building a simple device with which the bearings are removed quickly and accurately.
- small channel;
- bolt М8-М10;
- nut М8-М10.
Simplified Puller Manufacturing Process
On a segment of a small channel, you need to drill 2 holes opposite each other with an 8-10 mm drill.
You need to crash into one of them to get an open window.
The width of the cut must be sufficient to enter the shaft with the bearing.
Then a bolt sharpened for a cone is inserted into the hole opposite, and a nut is screwed onto it.
Thus, holding the nut with a wrench and screwing in the bolt can push the shaft out of the bearing. It takes literally 10 minutes to make such a simplified puller, so it makes sense to do it, even if you only need to press out one bearing.
