Please help! RF Weird focusing problem!

I just received a Fuji GS645 fold medium format camera and the focusing is weird...

When I look inside of viewfinder, the translucent part is on the left to subject and it moves to right when I start to turn the focus ring clockwise, it changes from seeing a double image to the two images being completely aligned and then when I turn the focus ring all the way to right than the translucent also move to the right side of the subject but the problem is when I turn the focus ring back to left, the translucent part won't move until I close the lens and reopen. The rangefinder patch is just stuck at the right corner....The lens moves back and forth tho.

When I turn the focus ring about 70% to the right then if I turn it back to left, the translucent part does moves to left.

There's no battery or film in the camera but I don't think they are causing the problem with focusing...wouldn't they? I've heard the battery is for meter only...

Does anyone know what's causing this?

Thanks,

Why post in two different forums?

Sorry, I realized this is more question for Rangefinder after I posted this up here. I tried to delete this but I couldn't. Please delete this.

If the camera has not been dropped on opened, then a likely diagnosis is thickened grease or oil at a pivot point I the RF mechanism.
