Yes one pair of my bearings were in upside down . My machine is ser no. 286 04-2007.
If you need to strip down the spindle assembly I have notes from when I did it that may help.
If you fit any make of replacement bearings - contamination ex the factory is not an issue as they come without lube. It is critical the amount of grease - too much will cause overheating - and use the correct grade. The wrong grade could cause overheating, melt out or drop out. I think its worth the expense to use a special spindle grease. EG Kluber isoflex LDS 18 special A
I am trying to remember if there is a way you can see if your bearings are in upside down also - without dismantling the whole assembly. Let me know if that would help and I will study my notes etc.
Thanks for the information Keen, I have been keeping a watch on the spindle and it has not made any noise in the last week, I still need to talk more with Tormach but I am pretty sure the sound is coming from the spindle and not the drive system. At least I see that the bearings are available on the Tormach website and not too terribly expensive if the thing craps out a year from now or something.
Do the bearings require a press to get them out/off?
