2836-2 Day Wheel Problem

[Folkvisor]

My 2836-2 works really well but the day wheel doesn't show the complete Day name in the window. It changes but I always have to tweak it with the stem in the morning. 

Is there an easy fix for this?

There could be some problems with inner components or maybe just in need of service...

I'm pretty sure everything is intact. I'm wondering if the problem could be the screws holding the movement on the spacer are a little too tight. Or, perhaps, the daywheel spring needs a little D5. The spring is in place because I can move the daywheel with the stem.

It works just fine out of the case. I'm not sure what its problem is.
