42mm White Dial "Explorer" GMT Watch Kit Installing the hour wheel spring question

Hi, I’ve just received my Kit today and try to follow the Video and Instruction guide.
I’m currently having an understanding problem with the hour wheel spring installation step.
The instruction shows on pic 1 this: Link to pic 1
on pic 3 this: Link to pic 3

Do I have to push that little spring wheel don or how do I have to do it.
Regards,
Eric

Just put the spring onto the wheel. No need to push. Pic 1 is for showing you where the wheel is. Pic 3 is how it looks when it’s done.
