OBL 43/11-30H bearing replacement

[BenScoobert]

Has anyone done a bearing replacement on the E550 stock motor OBL 43/11-30H ?

Mine has a whining sound and 1/4mm play when pushed horizontally.
Any idea what bearing are in it?
Where to get them?
Is it worth it?

I have one of them, the top broke away but i cannot see a way of opening it up if it wasn't broken??? There's a number on the bearing wether that would help???

If you think it is unopenable without damage then I might just replace it for the sake of the hassle.

Anyone succeeded with one?
