Rotex RO 150 E Replace bearings
« on: January 21, 2018, 02:50 PM »
First post, bare with for a newbie question.

Got my first used Festool, and it turns out the bearings are worn out. It makes an unpleasent sound (not terrible, but definitely not ok). I dissassembled it partly and it is a clear wobble and play in some of the bearings, but I am not sure how to get the bearings of the shafts and seats the best way.

Is there some instructions/manuals somewhere? I want to avoid the cost of sending it away if in anyway possible. I assume it is quite possible to diy it without special tools?

You're in virgin territory here, I don't think many people here have experience with that, never read about it here in the last 9 years I'm a member.

Bearings in powertools are often pressure fit, sometimes with a temperature treatment (hot or cold) to add some extra clamping pressure due to shrinking when the temperature evens out. Not sure if Festool uses that.

I do think you might need some special tools or custom made jigs to distribute the force evenly around the bearing. Let us know how it works out.

If you are in virgin territory from Alex's perspective that is saying something. Maybe some pictures would help us (Alex) advise you without getting you into part damaging trouble.

Depends on the bearings. Heat/cold are your friend. You'll need a way to extract the old without damaging the bores. Again need to see pictures. I've R&R'ed pretty much any bearing situation you'd encounter.

My Rotex just broke after about 4 years. If you do not have experience in working with bearings and gears and understand how to shim gears I would suggest sending it to an authorized service company.
I have been working with percision equipment for over 35 years so it was pretty simple for me. A nice little arbor press would almost be a must but with a little ingenuity you could use your vice and another set of hands to ease the process.
My advice to you would be take a lot of pictures as you disassemble your sander. My armature and bevel gear gave out not electrically the gear stripped. I went ahead and just replaced all the bearings while it was apart bearings are cheap. Assembly can be a bit tricky if you don't know what your doing you will just be wasting your time and money. I also went ahead and just replaced the brushes since I replaced the armature. It works perfect. Rotex sanders are loud and do sound like it's about to come apart right out of the box. My rebuild went perfect I spent a little over 100 US dollars to fix it well worth it considering I would have to drop a bunch of money to purchase another sander. Hands down the best sander on the market I'm going to purchase the RO 90 soon since most of my projects are small.
