I've noticed my 690 has been getting warm on the chuck end and notice a bit of noise from the bearing the other day. I'm planning to replace them and found a decent walk-thru of that. Anyone else done this?

Any recommendations for bearings?

I assume I probably should go ahead and order some brushes too?

I used double sealed (versus shielded OEM's) for my Colt. I wasn't willing to go to ceramics or hybrids just for a trim router ;-) If your 690 gets used hard like in a CNC I would look to hybrid or ceramic. They are an order of magnitude more but, last many times longer in tough situations. I buy from VXB although I'm sure there are others.
