A:

Thank you for being Sears’ valued member and for contacting SearsPartsDirect.com with your question about your Craftsman sander model 315117270.  I am so sorry the orange retainer handle has come loose. I have located that part and the missing retainer screw. I have included the links below for the parts. There is a photo of the lever so you can verify this is the part that came loose. If the parts need to be replaced, you can use the links to order them. 

In this case I recommend the sander be repaired by a qualified technician. This product has a double insulated system. Any repair of this tool requires dielectric testing to ensure the operator’s safety. To avoid the possibility of alteration or damage to the double insulated system, service should only be performed by your nearest Sears repair center. The repair must be completed using the necessary diagnostic and testing equipment to assure continued compliance with applicable UL requirements. After the completion of the repair, the product must be checked using high voltage testing equipment to prevent a severe shock hazard which may occur if the part is not properly installed and tested.  

For these safety reasons we do not have a technical manual or electrical diagram that we can provide you. 
Here at SearsPartsDirect.com we love to help you with your do-it-yourself repair projects, but in this case, for your safety, the sander should only be repaired by a qualified technician with the proper testing equipment. Thank you for your understanding in this matter and thank you for choosing Sears, we appreciate your business.

This is shown as if the pulley is threaded onto the motor shaft. You'll need to put a screwdriver or pin into the fan (on the rotor) to hold it while you unscrew the fan. It seems like the last time I had to take one of these apart that the fan was damaged by doing this but there was no other way to get the pulley off. If you can get the rotor (and fan) out of the sander then you can hold the other side of the rotor shaft with pliers while you unscrew the pulley.

Thank you for using Manage My Life!

Wade, Thanks- your advice got me going in the right direction, however I couldn't remove or loosen the pulley for fear of damaging the fan or the shaft at the other end that seats into the bearing. I tapped the shaft out toward the fan assembly and it all came out- armature and all. I put vice grips on the stub of the shaft that goes into the bearing but I started to burr the shaft. I stopped. However this gave me access to the fan area and I cleaned it and could see where the problem was. Things are spinning fine now, it's just that there is a bit of give in the fan bearing (which I couldn't get to) and that eventually will cause problems down the line.When I installed the armature back into the bearing I left it out a bit. Not completely flush with the bearing. I put the screw in and closed it up. I think this help my problem too because the drive pulley had tighten itself on the shaft form use and was rubbing the fan housing. This is not an old sander with very few hours on it. I will consider a better built machine next time.

Thank you for your question on the dust collector no working on the belt sander.

If you have an air compressor in your shop you may want to take the bag off the sander and blower backwards into the dust chute to see if you can get the build saw dust out of the blower fan.

To get to the blower housing on this sander will require removal of a lot of parts to get to the fan. That is why I suggest using compressed air to blow out the build up.

Please where a face mask and safety glass since this dust will be very fine and you do not want to breathe it.

If this does not solve the problem then please let me know and we can go through the dismantling of the sander from the drive belt side to get to the fan housing.
