Changing bearings in gearbox

[BauDemo]

I have opened the gearbox and want to change the bearings in it.
I see the markings on the bearings that are in now, but wonder if you managed to find a better bearings.
Or if you have a gull list of all the bearings that are needed.

Thanks in advance,
Nikolay

You probably have the original spare parts catalogue? Just checked it, only manufacturers partnumbers are listed. So no help there.
What's the reason for opening the gearbox?
It is recommended to use synthetic gearoil instead of the original thin hydrolic oil. And fill a bit higher than level plug.
