Disassembling ES 125 REQ Plus - stuck spindle bearing

[MikeJW]

Hi - seeking some guidance from the good folk in the FOG. I need to replace a broken fan on my ES 125 but cannot remove the bearing cover for some reason as the spindle bearing seems well and truly stuck to the spindle (in the red circle of the image). I'm pretty sure there are no retaining screws left, and I have removed the spindle washer and circlip and soaked it in WD40, but the armature spindle seems well and truly stuck to the spindle bearing. I've tried various sizes of persuader, and have attempted to heat the alloy cover with a small blow torch, but it seems stuck fast. Any (sensible) suggestions would be welcome!

If the end of that exposed shaft is threaded, stick a bolt in it and give it a few good straight inline whacks with a hammer. No need to be delicate about it.

Thanks luvmytoolz - I'll give it a try and report back, hopefully with some success

...no joy, even with a club hammer. I'll purchase a puller and if that fails it will have to be consigned to the bin unfortuantely, which is a shame as it was my first every Fest

Maybe an owner's manual will help?
I found this in the Resources menu above. Check for your specific model.....

Thanks - I've spent all morning looking for one of these and it's just what's needed for replacing the motor brushes (if I can get the seized bearing off). I have a feeling this sander is going to end up like Trigger's broom...

Puller arrived today and worked its magic.

Glad you got it off.
Press fit on the shaft would be normal for that bearing application.
