Hi, I don't know this lock, so I can give you only general answers...
The lock appears to be a "front driver"/"front drive cam", i.e. the solid disk coupling with the dial is in the front when looking from outside the safe. The code wheels are the disks with the many holes in them. Then there are smaller parts with a big hole, that have one or two hooks. The code wheel together with one of these parts makes up a coded wheel. The position where the hook is going through one of the many hole is determining the combination of that wheel. The part with the two hooks is for the wheel next do the drive cam and the part with one hook for the other wheel. The drive cam has a pin poking out. This one is catching a hook and moves the next wheel. The second hook will catch the hook of the most distant wheel to move that. I assume the hook parts should be behind their wheel (when looking from outside the safe). If the part with the two hooks has hooks of different length, then I would put the longer one pointing towards the driver and through the hole of the wheel. Then there are rings with noses on the inside. You do show them together with the wheels, but they should be separate parts. The prevent that one disk moves the next just by friction. So there should be one between driver and wheel and between the wheels.
To set the combo you assemble the lock with the hooks going through some random holes. Then you look through the second biggest hole in the rear of the lock case. Turning the dial clockwise/right (when looking again from the front) you wait until the rectangular cut-out of of the rearmost wheel is at this hole and under the long pin, which should be visible there. Look which number is at the index on the dial. That is the first number of the combo. Then turn ccw/left until the same happens with the other wheel. Again note the number on the index, which is the second number of the combo. Finally turn cw/right until the lock opens and the dial stops. There are 25 holes per wheel, so you can set only 25 numbers even so there are 50 on the dial. If you don't like the combo move the hooks around the wheel.
