The 304 bushing has stuck to the shaft – is there any way to fix this?
Thread Content
When removing the pump, it’s possible that the 304 shaft sleeve has stuck to the shaft; no matter how hard I try, I can’t pull it off. Does anyone have any good suggestions? Shaft diameter 30mm
The grinder cuts through! Take it apart and check the shaft runout to see if it can still be used!
I’m most afraid of encountering this situation; if it really can’t be removed, the only option is usually to damage the shaft in order to get rid of the sleeve, as a way to mitigate some of the losses. But here’s some friendly advice: 1: Do not use the same material for the shaft and the sleeve ； Anti-locking braking ； 2: During assembly, it is essential that sealing gaskets or O-rings and other sealing elements in all relevant areas are not missing and are properly installed, to prevent the medium from leaking between the shaft sleeve and the shaft. 3: Apply lithium-based grease inside the shaft sleeve during assembly to facilitate disassembly.
If possible, it can be turned using a lathe. Then check whether the pump shaft can be used again
Use a gas welding torch to heat the area around the shaft sleeve quickly and evenly, then swiftly remove it using the prepared copper rod or another tool! :victory::lol
Turning on a lathe is possible if conditions permit. Then check whether the pump shaft can be used again
I’ve encountered this situation before; the bushing was no longer usable, so I put it on a lathe and ground it down to a thickness of 10–20 microns. It can be easily removed without damaging the shaft
The simplest way is to use a cutting tool to make a cut in the shaft sleeve, diagonally! Use a pin to pry it open when it’s near the axis! We do this often!
