7 tooth steering box

[wkuehnis]

Hi,

I have a steering column maybe from 1929. It has no oil plug, so it uses only grease. it has 2 grease nipples.
It has a black splined steering wheel.
I don't understand the following:
I insert the 7-tooth sector and connect it with the steering worm gear on the steering shaft.
When I turn the steering wheel now, then I can turn the pitman arm, but if I fix the pitman arm, then the steering column moves upwards and comes out of the upper bushing.
Is there no fixation for the steering column in the steering housing, because only the sector should turn and the steering column should only rotate.
I know, at the lower end, I have to install the spider with the spring and it's fixed on the light switch rod with the Spider retainer, but this is not designed to handle such a high load.

What am I missing ?

Thanks for help
