Hallo Eivind,
sorry, but I forgot to think about some additional facts/problems:
You will have to find out, what type of clutch is mounted!
There are two versions: duplex clutch and single type.
I assume it will be a single type. In this case You need a PTO gear for this clutch type!
And!!!
Some MBtrac in the army were used as plane tractors and have built in a torque converter.
In this case You have only a 4speed gear and 25km/h or a 7speed gear and 40km/h.
For agricultural jobs this is not very much…
There are two types of front threepoint linkage. The 1-cylinder type fits all MBtrac but has only a capacity of about 1200kg. The 2-cylinder types fit from MBtrac 700 up to 1100 (441) and has a cap. of about 2 tons..
The pto gear is relating to the clutch type, but MBtrac 440.162, MBtrac 441, Unimog 403, Unimog 406, Unimog 416 are the same. Maybe it will be easyer to find a used single clutch matching PTOgear from a Unimog, because single clutch type MBtrac are rare. Unimog must be about 1968 and later because the gear was completely modified at this time. (MBtrac and newer Unimog have built in release "G" of the gear. The name of the gear is UG2/27(G)). Earlyer Unimog have built in release "F" of UG2/27. Release F does not work in any MBtrac. Newer MBtrac 440 from 1982 (new driver cab version) has a quite different gear (UG2/30).

...meanwhile some additional questions about this appeared. I will find out and tell You, when I'm sure about it.

Die 3 MBtrac-Grundsätze:
1.) Ein MBtrac ist zwar nicht alles, aber ohne MBtrac ist alles nichts!
woraus folgt:
2.) Ein Leben ohne MBtrac ist möglich - aber sinnlos...
doch zum Glück für die vielen Nicht MBtrac Besitzer:
3.) Nur wer einen MBtrac besitzt, weiß, was allen anderen fehlt...
