Hi tsakali

That main gear wobble looks excessive.
Before you replace it, just try one thing.
Pop the main gear out, undo the four screws that hold the hub in place, then see how easy it is to push the hub away from the main gear.
If it is at all tight, that may be your problem.
If so, use a little fine emery cloth and rub around the edge of the hub, a little at a time, until the hub fits into the gear with no, or very little, pressure.
Then re-tighten the four screws in sequence.
Imagine looking at a clock face you tighten the screws in order
12 o'clock
6 o'clock
3 o/clock
9 o'clock
and so on.
Each a little at a time, with a dab of threadlock, until snug.
Do not overtighten.
Might not work, but worth a try.

Cheers

BL
