Title: 4 gear transmission 600 9A from 1932
Post by: klaudius on February 09, 2019, 06:59:45 PM
Hello. I just finished with my 4 gear transmission of my 600 9A from 1932. All bearings new, etc. Unfortunately, the lower aritier screw was a bit worn. Maybe someone has the full length? Even better would of course be intact replacement ... Greetings Claudius

I don't understand what you mean by the "aritier" screw. Could you indicate it on a photo?

Hello. At the bottom of the gearbox is a screw with a spring and a pin. This pen is a bit worn with me. Need the length and shape of the tip to rebuild. Someone already renewed something like that? Claudius

I will get the plunger from my spare gearbox and get the details you need

It is so that with me the tip of the pen is worn out. As a result, the form and length are no longer measurable. Many Thanks .Claudius

Hi Claudius I hope this helps..
I do not think the radius at the end is critical but there must be one or the selector drum will be damaged

Many Thanks. I was looking for that. I will have the part built now. After that, the transmission would be completely overhauled. Nice greetings from Germany. Claudius
