Hi Dave,What kind and grade (viscosity) of oil do you use in the main platter baearing?
I suspcet a too much thin oil could cause the trouble.
Correct viscosity grade would be ISO VG 46 or SAE 20.
Used with too thin oil such as WD-40, there is less friction (but it will end up causing the bearing wear).
Follow Ups:
I don't see any viscocity data in that link.Unless someone comes up with another idea, I will change out the oil tomorrow night.
Dave
PS I used the Tufoil in the motor, too. Do you think I should change that out too? Or start with the main platter bearing and see where that goes?
That is possible. I am using a product called Tufoil...Here are the specs:
Oils for modern car engines are NOT suitable, because those oils are designed for high revolutions (in some cases, nearly 10,000rpm!) and for use in extremely high temperature. As you know, 33 (or 45, 78) rpm is relatively very, very slow and the environment is in low temperature.You shoud see the different page for the spec of the oil, which I've just found.
TUFOIL FOR ENGINES SPECIFICATIONS
Kinematic Viscosity (ASTM D445)
@ 40ºC (cSt) 958.2
@ 100ºC (cSt) 128.9
Viscosity Index 243One of the suitable examples (Regal B&O 46)
Kinematic viscosity
@ 40ºC (cSt) 46
@ 100ºC (cSt) 6.8
Viscosity Index 101Please compare viscosity figures of @ 40ºC (cSt).
TUFOIL is too much thin!!
Sorry, I made a misunderstanding.
