Me and my friend are rebuilding a gasgas ec 300. We tore it down some time ago, ordered all the bearings and now we are putting them in. We didnt take any photos while tearing it down because there is a pretty extensive service manual.

Now however when putting the bearings in the clutch side we encountered this hole that we have no idea what is for. This hole isnt in any manuals or photos/videos we found online. Im assuming a needle bearing belongs here, but what for?

Any gasgas gurus here that could help?
