DT400C. The bearing carrying the clutch shaft (6205Z) has a seal on one side but not the other, looking at bearing suppliers, the new ones come with seals on both sides, do I Just pop the one side out?
Seems strange but it has the seal in the pictures in my manual but can't find a pic of the other side.

  
 

You want a shielded bearing...  not a sealed one.  (Shield code suffix is usually "Z", sealed bearing code is usually "S" or "RS")

Shield goes to outside like your picture...  yes, just pop the inside shield out if you get a 2Z

Thanks MarkT,  yes I've located the right bearing but having to pop the one side out threw me, is this the norm, why not just have an open bearing?

According to Yamaha literature I've read, it must have a shield and that shield must be on the outside (clutch) side or the bearing could starve for oil. 

Plus, just for info, the other Bearing 6305 N, 6305 NR is the same but just has the snap ring pre fitted.

The output shaft bearing 6305 is a 6305XN on that model...  the X designates a special radius on the back side which is important to have so it presses into the case all the way.

O shoot, really?  It didn't have that bearing in, just a 6305N, and I've gone and ordered one too.

Hi all, 
Seems like I've got the same problem, ordered the correct (listed) bearing for a CT2 but it's come with a cover on both sides, the current only has a cover on one. How do I pop one side out without damaging the whole bearing? Also, if its listed as the one (yamaha part number) I need is there any real harm in just using it?

I ordered mine from the number on my existing and chose SKF as my brand of choice, and it came with just one side sealed.
