The needle pulls straight off
Then two tiny screws to remove the face plate
After that I think it’s maybe only clips and pins but it will be fairly obvious
The needle cup and it’s clock spring come out together and just be gentile with them and it should be easy to reassemble after
You have to remove a few worm gear drives
And get the magnet exposed
It’s very doable and it should all go back together as it came apart
Do not get any oil or lubricant onto the clock spring or else it will collect dirt and could cause binding of the spring from winding to winding resulting in poor operation.
Just try to pay close attention how stuff comes apart to remember how to put it back together
There are many junk trucks with usable parts if anything breaks don’t freak out, it can all be found still fairly easily and cheap
