Top 20 Porter Cable 332K Quicksand Random Orbit Sander W/ Case Questions & Answers

You probably did. They are pretty good about their warranty so I would bring it back to the store and get a new one

there is a belt from the motor to the pad that has apparently broken. Go to dewaltservicenet.com and you can download both the parts breakdown and the operators manual. If I have helped you would you please vote accordingly and thank you

I would take a lok at the switch, sometimes they become full of dirt and make intermittent contact

Hi, Sanders are prone to getting lots and lots of dust inside the unit. The cooling fan makes this problem inevitable. The only way to fix this is to take it apart and and blast it with a pressurized air tool. Hopefully this will bring back some life to your sander. The effectiveness of this procedure is dependent on how well you can remove all of the dust. hope this helps.

Look at eReplacementParts.com and the parts diagrams

It sounds to me that you have used the sander a lot and the vibration has broken a wire or it's about to break on the field windings. The brushes you need to look at to see if worn. But I kind of think wire problem. I had this happen on mine and opened it up to find this is what happened. The sander would be turned on and would not operate until I turn upside down and it would work. This is great if you are sanding upside down but this is just a sign that you are on borrowed time as this will eventually not turn on at all. I was able to fix mine with new wire crimp connection and solder with heat shrink material. If not you can order new field winding if this is what is wrong. Cleaning up the sander won't hurt either. You might want to see what a new sander will cost vs. part. Good Luck!

how to lube sander

usually you would need a bearing puller or a bearing splitter to remove bearings, give me the exact brand and model number and I will find a breakdown for the tool and let you know more if needed.

There's a belt in there that may have broken or slipped off its track. That's just about all that can go wrong, unless a bearing seizes. You can see an exploded parts view with part numbers here, and download an instruction manual with some photos here that will help you to sort it out.
If you click on the parts numbers (in the list) you'll be able to check availability and/or order them...There's also a link to service centers if you're not comfortable doing the repair yourself.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

Just solved my problem with Porter Cable 333 orbital sander which just groaned. I thought the worst. I carefully took it apart on the garage floor and immediately suspected it needed lubrication as the motor turned hard. I used my flexible long plastic tube lubrication and put some on the bottom bearing shaft the best I could. I worked it around and around. I began to feel it turning easier. I applied more oil and kept moving and it became completely free. I put a drop on the top bearing even though it was loose. I put it all back together and it works like new. Lesson: do not look for the worst when a tool quits. Suspect the culprit to be lack of lubrication!!!

Go to Dewaltservicenet.com and in the center of the page under needing parts type in your tool model number it will take you to another page and scroll down to the type 1 or 2 and click on it. It will bring up an exploded view of this tool. Why do you think that you need brushes? usually I have to replace the bearings and the brushes are pretty durable. Let me know if I can help further

There is a screw holding the pulley on remove it and what I would do is take 2 screwdrivers and gently pry up from either side, The bearing is generally a loose press fit. You might want to take a look at a breakdown at Dewaltservicenet.com and type in your model number so you can see what it looks like. Good luck

It could either be that the brushes partially burned I would check to make sure your brushes are in good shape and take it out of the helpers pay ;)

call this company, they have the different types I purchased from them and no complaints https://www.ereplacementparts.com/porter-cable-7800-

The brushes are not replaceable - it is an entire motor assembly. 1) remove the 2 screws holding the top handle on 2) remove the 2 screws on the top of the housing (front either side of switch) 3) remove single screw holding cord hook (rear side of housing) 4) remove small torx screw in the shaker handle and remove the handle Flip over and using a screwdriver begin to pry the top cover off the housing (easiest to get the front side off first)

first you need to remove the tank and get rid of the rust with a rust kill agent, vinga or chemical type with corrosive converter, then liquid paint the inside of the tank, swilling the paint inside and leave to drip out. then find a high pressure line filter, these are a solid filter and put in line. to stop this happening again to the tank you can also put a drop valve in place and when not in use press to release the air inside as this is what rusts the tank. but after the restoration it should be fine without a filter.

Is this it? https://www.manualslib.com/manual/132302/Porter-Cable-Bsv750.html

take it back for a warranty exchange make sure that the voltage listed on the machine is the same as used in the house

Remove the screws holding the 2 sides together and expose the wiring. Remove the remnants of old cord and replace with new one. Reassemble.

Hello Terry Dugger, If it is suddenly stopping it could be a bearing problem... but if it is slowing down like a tired battery... DEPENDING VERY MUCH on what kind of battery you have (undisclosed model ...purpose tool)... "some" RECHARGEABLE BATTERIES develop a memory... and are reluctant to go BELOW that level. Typically these are seldom used tools... wiki does a pretty good description on these batteries (types). There are folks out there that think it is CLEVER to DISCHARGE these thing... or pulse them to BREAK THE MEMORY. Likely to case a fire or explode as to succeed... If you are suddenly using a tool that has been stored foe a while... you MIGHT notice the battery time is getting better... Else just buy a replacement battery... Cordless tools do not do well if stored incorrectly. Hope this helps. https://en.wikipedia.org/wiki/Memory_effect Nickelcadmium battery Porter Cable Home Amazon com porter cable batteries
