Replace all bearings?

[Vintagewannabe]

I put this here because I feel like its all matter of opinion.
I am working on a full rebuild of my 73 RD350 at about 22k miles
When going through the transmission, all of the bearings looked good, but I figured I would throw new ones at it. The only one I haven't checked is the shift drum bearing.

Would you guys throw all new bearings at this? And what about the shift drum, considering it seems like it wouldn't take much abuse.
And what about those little Belleville spring washer guys under the clutch hub and main gear on the crank?

i always replace the input and output bearings the rest usually seems to hold up just fine in the transmission. I have changed them but didn't need it, ever. 0.02

Thats sort of what I figured. I'm guessing you feel the same about the belleville lock washers

Mine looked pretty good but I will be double checking.
