Ok, short history.

1) bought water cooled Chinese spindle really cheap (380v 2.2kw)
2) tested without water, worked fine
3) tested water pump only
4) leaked... from almost everywhere
5) disassembled back side... no O-ring on one connection.. water went into.. everywhere, bearings and all.
6) need to disassemble spindle to dry, clean and replace bearings.
7) two M4 threats at the front to push spindle core out of the shell,
8) rear bearing won't move.. even broke 2 bolts trying to remove it.

I don't know what to do now... should I try heating it up a bit? should I just try to force it? please help....

The rear bolt is left hand thread, unless you have the correct wrench to fit, you will damage the nuts the front nut you need a pin wrench, if you damage these parts you can through it in the trash, as you will mess up the balance of the spindle

The bearings are sealed so the water would not of got inside them

Hi Dm7g,

I changed my bearings and have pics if needed, but I used the thread below for reference, it's a 3kw but almost the same but a little larger scale. The 2.2kw should be a little easier because the left handed bolt on a 2.2kw no special tools needed.

Good luck,
Dan
