Hello all. I am in the process of assembling the gearbox and am now fiddling with the gear shifting mechanism.
The manual says that this tool should be used, but I do not have it, of course.
Please advise how to do the process without such a tool? How did you "calibrated" the gear?
Thanks in advance!

FWIW, when I rebuilt my plunger transmission (3x) I put back in the bits I had taken out, and fortunately I didn't need to mess with grinding the shift plate at all. I believe the door tool isn't a requirement - if gears aren't engaging or slipping out of gear, one can figure out which way to grind - and those guts come out easily enough even with the transmission in the frame... Sorry I can't provide more detail.

You can always sacrifice a door to make one, too.

Already fabricated my own.
Gear shifting is like a charm now.
If I will send every item over to an expert, the bike will never run again. I have no budget for it and there are also no experts over here in Israel for these ladies. Beside, how will we be able to proceed with this hobby? To learn? To grow and progress? I think that this forum is - partly - for such cases and I hope that someone in the future will find his answers over here.
Thank you all again – Michael.
