Hi does any one has experience with integrating the keya motor

That’s the point, you need a machine shop. But where to get the right drawings for it ?

I found out, due to the small inner diameter, fixation with a contra nut is not possible. Especially with the height adjustment of the steering shaft’s.

Recently I found a offer for these parts at aliexpress:

Traktor autonomen fahren motor zubehör, adapter motor flansch luftfahrt stecker elektrische lenkrad lenkung motor spezielle|DC-Motor| - AliExpress

Thank you
