Black and Decker Sander Repair and Tear Down BOLTR

[@ModernDIYProjects]

In this video I tear down a Black and Decker Orbital Sander that was bound for the Garbage. I find out what was wrong with it and fix it, plus show you guys the inner workings of these sanders. Many tools are based on the same mechanics of this sander so this is a good tutorial to show you how these tools are put together and how easy they are to fix. Now you don't need to be afraid to tear down a power tool and fix it yourself if you need to.

My black and decker is sparking where it rotates. The side of where all the wires are connected. Seems to be friction between these two pieces on the sides of the drum If you will. Not sure why that is. Thoughts?

[@ModernDIYProjects]

Yes, sparking is normal for most older electric tools. The sparks come from the carbon brushes running against the armature. That is how electricity causes the drum to rotate by alternating the polarity. A small amount of sparks when you turn it on or off is normal. If it is sparking ALL the time then the brushes have probably worn down to nothing and it's at the end of it's life. You can replace the brushes if you can find replacements but most folks wont do that.

@@ModernDIYProjects it sparks as it rotates between those 2 pieces on the side and shorts. These two pieces on the side is actually a rectangular metal piece in a plastic rectangle against the drums. Im calling it drums but not sure what it's actually called

Hi, my sander started making a rough noise, once every few seconds jumping erratically. After a few minutes it doesn't move erratically anymore, but just constantly making a rough noise, as if the motor is hitting something as it rotates and enough to make the RPM sound a bit slower. I suspect the system that moves the pad back and forth has broken. I've taken the cover off, but can't actually figure out how the motor makes the in-line pad move forward/backward. I tried moving the pad back and forth and it doesn't budge at all. I think I put to much force while sanding and overstressed the pad component. Any ideas how I can inspect to then attempt replacement parts/repair? Thanks!

To be honest if your sander is old like this one, then it just isn't worth fixing if you have to spend money to do it. Your sander probably got worn out by a lot of dust from sanding building up inside and ruining the bearings, the brushes or the stater. The brushes are a cheap and you can check that first if you want to try to fix it. You can also just clean out the guts of the sander using WD-40 as a cleaner. Shower the insides with the WD-40 and let it pour out. It will rinse out any crap build up but wont harm anything. But if parts are needed, then the parts will cost you more than buying a new, modern sander with a lot more power and features. I don't like to throw away stuff but eventually they all go bad and economically it isn't smart to fix them.

I am fixing my brothers sander for him. I am replacing the power cord. While i have it apart I cleaned everything up. My question is do I need to grease the bearing in there or anything else. I am new to the fixing stuff game and want to make sure I don’t burn up a bearing. Thanks in advance for some knowledge.

[@ModernDIYProjects]

Look at your unit and see if its a sealed bearing (probably since it's a dusty environment) or an open bearing. Open bearings need grease, but sealed bearings do not. Use WD40 as a cleanser on the bearing and any other moving parts and that way you clean and remove any dust and moisture that the bearing or other moving parts may have. Good luck!

commutator?

[@donttrackmebro6164]

Was that a piece of lamp cord in there?

[@ModernDIYProjects]

You have a good eye. That is exactly what it was.

Crappy lamp cord
