When removing the bottom braket which side is clockwise and which is opposite?

If you have an English threaded bottom bracket the non-drive side (left side) is right hand threaded (counter clockwise to remove) and the drive side (right side) is left hand threaded (clockwise to remove).

Will this work on a shimano un300 bottom bracket?

Yes. One side is clockwise and the other opposite. You must use a clamp or all your weight on the impact wrench if the bike is old.

The right side is reverse thread.
