I had the motor apart today - see attached pictures I took on the kitchen table (where else to do main repairs :-))

The sinner is the bearing in the bottom - it was complety 'welded' to the shaft of the rotor.

Second picture it is removed.
Below in housing there is a spring/ring that locks the bearing.
I have to find to get this out, to fasten the bearing again.

Very insteresting. Is there any space to fit a small ball bearing down there?

Ball bearing for a window motor?... sounds a bit like "over kill" to me Wink

If you mess it up and ruin the motor (like I almost certainly would Cheesy ) I belive they are lifted straight from a Talbot Tagora... might help if you end up looking for a new one.

Hi Henrik, I had the same problem, and I did cut off the small end off the housing and made a new bearing off brass,
it works fine for a ½ year now.

But they are just a few kr... nothing compared to the cost of my labor Wink

Ball bearings are only for torque forces, but in this case all forces are in the axiel direction.
The weight of the window is transferred to the axel (the gearbox has no bearings for this)

There is a small plastic piece in the end of the rotor axel - this takes all the forces to outer chasis of the motor.

I have cut a little in the photos, so you can see better.

Correct though most ball bearings can take axial forces by design.

Nice drawing, thanks for sharing it!

The three M3 holes are for screws pushed into the remaining part of the motor housing, I suppose. To attach the new bearing?

Simple, and probably useful to others. What will they cost a piece Wink ?

Hi Finn

Thanks for  the drawing !
It's a nice and easy solution, I think.

I had all parts out, except the locking ring.
To solve it, I drilled a small hole Ĝ3 in the angled side of the house.
After this, I could get the ring out and also reuse it.

see photo attached.
