Recently my PC 333 ROS started making a grinding noise while slowing
down (after turning it off). Opened it up last night and it looks like
the lower ball bearing is about to seize...the upper one turns nice but
once you grip the lower one the shaft doesnt turn so nice anymore.

I wasnt sure if it just slides right off, but I gave it a tug and it
didnt budge. Is the bearing pressed onto the shaft? If so, any tips
on how to remove and reinstall it? (going further, anyone have
measurements on the bearing? Im pretty sure I could find an equivalent
replacement locally if I knew the size)

I like the sander, considering the part is only 5 bux I figured it
would be worth it to fix over buying a new sander. Am I wasting my
time?

Thanks!
