Mioyta 8200 Thirdwheel

[Keloux]

Hello Community,

I am currently working on a Miyota 8200 and I am confused that they oil the third wheel with 9010 instead of D5.
Is it related to the fact that the third wheel drives the second shaft ?

I'll attach a photo.

Happy Holidays and Merry Christmas to you all !

You should oil the third wheel jewels with 9010.

@Rafael thank you. But why ?

Normally (Unitas 649x) you oil the third wheel jewels with D5. Why here with 9010 ?

Can you tell me the reason?

Moebius 9010 is used on high speed and low torque/pressure areas as D5/HP1000/1300 is generally used for high pressure/torque and low speed areas. See Nobswatchmaker

@Watchtime 

this is how i learned it. And the third wheel has a high pressure, so it would be oiled with D5 ?

Or is this construction the reason why it has a low pressure ?
