Rubber Pin 263002-9

I bought a new base with the felt pad included and brushes years ago from here and the feet.

At the time I needed the base because it was bent and the feet were shot.

This time I decided to replace the brushes and clean the entire sander out , it is a BO4510. It was full of sanding dust . All I needed was a screw driver .
I took the sander completely apart washed the 2 case half's in dish soap and brew them dry. I also brew all the sanding dust off the field and armature and cleaned the commutator because it was covered with carbon and cleaned the brush holders.

The bearings felt fine . Then I put it all back together , took photo's to know how it was so I could put it together as it should be.

I replaced the two rubber pins that keep the base bearing and lower bearing from spinning , they were flattened .

The only thing I would advise is when you install the base to the feet make sure the sandpaper clamps are even with the base edge , you will see if they are not . To do this loosen the 2 screws and take a small screw driver to move the feet which moves the paper clamps then tighten the screws then do the other side. If you don't the paper clamps will not hold the sandpaper well. I decided to look and noticed they were not lined up proper. You cannot simply slap the base on .
