Some time ago I asked how hot your ROS gets because my Bosch would get so hot that there were parts that you didn't want to touch. Recently, I took it over to my daughter's house to work on a couple of things, and the first time I turned it on, the sanding pad flew across the garage. A part called the "carrier", or "Driver" snapped. So I finally got around to ordering new bearings, etc. for it, and of course the new driver. I have taken it all apart, cleaned it up, and installed the new parts. Assembly was simple enough as there is only one way it all fits together again. I have used it a couple of times now and it no longer gets anywhere near as hot as it used to, and it is smoother too. But! IT BLOWS! After a sanding session with it, there is sanding dust everywhere.
I disassembled it again yesterday, and there is dust all over inside it. There is more dust inside it after an hour or two of use than after all of the years of using it before I disassembled it the first time. There is even a lot of dust in the motor up in the brushes area. It's almost like the thing has decided to run backwards or something. The dust cannister does get dust in it, and it will fill up. But if I "dry run" the sander with no cannister on it, there is a little air coming out the dust port, but there is more air coming out of the ring called . . . well . . . it is unnamed in the parts list. The user guide calls it a "damper ring".
If you have any experience or comments about why this might be happening, I'm all . . . eyes. :-)
Thanks,
Wayne
P.S. In the parts diagram there is a part called "Contact Strap". I'd also be curious what it's purpose is since it doesn't actually contact anything.
