Post Subject: Old oil to laboratoryPosted by measet on: 11/7/2017
Jam, Thanks for great infos.
I suppose the original MS ss platter is lighter than the gun metal one?
Are you filled with oil the whole bearing or just the bath in the bottom side?
The viscosity of oil would be ISO 32 VG as my new oil which is 46 VG looks thicker a bit than the original one.
Just for fun I sent out the old oil to laboratory and we will see the main properties of it. I have no doubt the test result will show us many contaminations (just think on the Fe what disappeared from the plate) which doesn't help to the lubrication, even can cause damage.
Please find a closer pic of dimple, looks strange:
To flipping the plate is a good idea but if we are thinking in long-term can be worth considering the idea of silicon nitride or other hard plate.
