Cam chain guide popped out?

[Np57]

What's up guys. I took of my top end to do a piston switch and one of my cam chain guides popped out. Do I just place it back? I see a little spot I think it sits on but I don't see anywhere it would clip on to? Thanks guys.

Yeah, they just sit in there

The front guide is held in by force. There is a "saddle" in the crankcase that the bottom of the guide sits in, and the top of the guide goes into a notch in the bottom of the cylinder head.
