Question: Sander Pad
I got a very short life from my last sander pad. It would throw the sandpaper off and , if I was not quick, the pad would hit the wood . Now it won't hold sandpaper at all. I am ready to yard sell this sander and change brands!! Mike

Here is some advise from Tinkerdave, one of our most active forum members on this subject.
Velcro on your sanding disc has a hard time sticking due to dirt ,saw dust and other debris getting stuck inside, which in turn makes it hard for the hook and loop sides to stick together. Because of the high torque loads placed on the hooks and loops they become distorted and damaged.
Before you throw your pad away first try this:
Remove the velcro pad off the sander and lay it on a flat surface. Take another piece of Velcro and comb through both the hook and loop sides, allowing the dirt to lift. Place another piece of Velcro on top of the older one hook on top of loop or vice versa and press and release it several times. This will loosen the dirt and take the majority of it link removed a metal toothpick small piece of wire to pick through the rest of the Velcro.Blow it off well with air. By doing this most of the dirt and saw dust should be gone. The toothpick or wire will help you get the rest of the dirt out.Hope this helps.Good luck.
Question: Bosch 3283 DVS Repair
I have had my 3283 DVS for 19 years, and it has never had any problems until now. The driver will no longer stay compressed into the bearing, and the entire pad assembly goes flying after short use. I am assuming that both the driver and bearing need to replaced. How do I get the bearing out?
Question: Bosch 3283 DVS Orbital Sander
My sander has a worn driver that needs to be replaced. I am surprised that this piece is worn because the sander has not been used that much. Does anyone know how to extract the driver from the machine? The driver is a 3 pronged plate that locks the sanding platen to the motor? The machine is an aggressive sander when its working. I am disappointed in the construction of it.

The driver is pressed onto the end of the armature shaft. You can sometimes remove the driver by prying underneath it, from two sides, with a couple of large screwdrivers. Of course care must be taken to avoid damaging the armature fan. If it won't seem to budge with the screwdrivers then the motor will need to be disassembled and the driver removed using a bearing press.
Let us know how it works out!
Question: Need Repair Info For Bosch Orbit...
Hi, i have never done this before so hope this is correct. I have two bosch orbital sanders 3283 dvs and 3107 dvs. Both have the same problem. The motor works but doesn't pass power to the orbital disc. I have taken them apart but can not go beyound removing the disc. and taking the case apart. Can't figure out how to get the link between the flywheel and the fitting the disc screws to apart. I assume there is something wrong with that link. Anyone have any answers for me. thanks much, jim

Usually what happens on these is the eccentric bearing binds up and it loses the orbit speed:( as far as the 3107 its best to just replace the whole assy 2606610901 Just remove the the cap screw and I believe you can then just pry or pull off..if there is some dis-assembly of the housing keep the breakdown handy to help you review..:) as far as the 3283 i believe the bearing you will need to replace is the 2600905111..you will have to remove the cap screw and c-clip to gain access.. these are clam shell housings so when separated pay attention to how everything goes back together in place and you should be ok [try to remove the screw side only if possible] hope this is helpful..?
There are some other posts on this website so you may want to do a search and review for more info..:)

I have the same problem with my 3107, motor works fine until you put a load on it. Then it stops. I took mine apart after reading your reply to Jim. Jim, the fan assembly comes off via a left hand thread connection on the armature shaft. The bearing race below the armature fan was stuck, (small vice grips and a hammer tap broke it loose), and the end was worn, but the bearing seemed tight. Anything else that could be causing my problem or could the bearing be bad without my being able to tell by feel?
