What is the principle and structure of the puller? Can our fan impeller be removed with a puller? If not, what's the best way?
It can be seen from the picture that after you remove the hexagon on the fan shaft, take off the cover, and you can see the fan shaft. After using the puller to mount it, it should be removable.
If the claw cannot be hooked, after opening the cover, there should be a bolt hole. Make a simple tool yourself and use a screw to pull it out.
There is a high probability of interference fit. You can reverse the pulling claw to pull the impeller. It is recommended to heat it first to avoid damaging the impeller. This really cannot be used as a tool.
The two holes on the wheel are for disassembly and cannot be used with this kind of puller. Special processing of screws and I-beams is required
This A-type transmission is really fucked. The motor needs to pull the impeller to replace the bearing. Anyway, if there is a problem, pull the impeller. After the impeller center pressure plate is disassembled, there are two screw holes. You can pull it by simply processing a work stake. If it cannot be pulled, preheat it.
