SOURCE: rockwell 361 belt sander wont run i have power to switch switch good bad brushes?

Brushes wear out often. Unscrew the brush caps and see if they are worn really low or if the springs are broken. If there is any burning on them, then replace them. Also those brushes sometimes stick in the brush holders because of the amount of dust. When you remove the brush caps, blow out all the dust you can.

The wires that go to the brush holders have springs that wrap around the inside of the brush holder (see picture). Check and see if those springs are broken or if those wires are not connected. Sometimes the fields go out in those but it's not too common. Almost never is it the armature (unless a bearing causes it but that's a mechanical failure, not an electrical issue).

Where do i find a dust bag for a rockwell belt sander model rc4355k

If you have the instruction book there could be an exploded diagram and parts list and instructions where to buy spare parts.

You could ask the retailer where it was bought.

You could try the manufacturer's website.

Failing those options there are lots of websites providing a spare parts service for power tools. Just google spare parts for your model of power tool...

I have an old 3 x 21 inch belt sander. I put on a new belt, but the belt tightening device is locked in the "open" position. How do I unlock it so it tightens the belt?

I have that same sander. Know what you mean. I usually end up using a hammer to trip the roller and get it to release by hitting the side(end) of the roller with the hammer. Good luck.

After replacing the brushes in my old Rockwell belt sander there is excessive arcing between the brushes and the oommutator and the unit doesn't come up to full speed.

Did you dress the brushes to the contour of the commutator?

You wrap the commutator with fine sandpaper and rotate under the brushes till the curve conforms.

If this does not reduce the arcing, then you may have an armature with a bad winding.

Belt sander adjustment

There should be a knob on the front of the sander which adjusts the front roller on the sander. If the belt runs off in the same direction each time try turning the knob as the sander is running and while watching the belt. If turning the knob one direction does not work try turning the other direction. If turning the knob does not have any affect on the way the belt tracks on the sander then you probably have a broken or missing part on the front of the sander. This may require taking the sander to a service center.
