Simple little tool to get the RA Axis Assembly washer out.  Most people don't have the spanner wrench or the angle to get that washer out of the rear bearing to remove or grease the RA Assembly. 

Print this out and insert 2 pieces of stiff metal (e.g. alan wrench 1.5mm) into the holes to fit the holes and turn counter clockwise. Paper clips may work in a pinch.

NB: IMPORTANT! There are 3 set screws that you need to loosen before you attempt to remove the washer. They are located behind the control panel. You must remove the panel to access and rotate the RA axis to access all three set screws.
