Post Subject: Intervention is neededPosted by measet on: 11/6/2017
Just take a look what I found after dismounting the bearing and motor.
No question, the intervention is needed.
I have already replaced all the caps and two trimmers, I removed the rust from the ferrit and magnet after that I lubricated slightly the bearing of motor.
The ceramic ball is cracked so I'll replace it with Si3N4 one, the oil is very dark and small dusts are visible.
I just drew a schematic about bearing.
I found enough lubricant in the bottom bath but the quantity was less than to be enough also for side part of the shaft. It is logical but somebody can confirm that the bearing must be filled full with oil.
I'm courious if the thrust plate was drilled intentionally or has been eaten by ball, the hole it seems too deep for a wearing sign.
I found here very fine hydraulic oil with viscosity 46 but it looks quite thick comparing to the original.
Jam, please let me know what kind of oil do you use, maybe do you know also the index of viscosity of it.
Regarding ss platter do you have the same design what Wellington invented or you just copied the parameters of gun metal platter?
Thanks a lot.
