Cycloid drive maintenance

[Eric Sooy]

I reads the manual on replacing the grease, but want to clarify things before opening things up.

It says to put a grease fitting into the fill port, then open the drain port.
Inject grease into the fill port, then stop when the grease comes out of the drain port. Plug it then run the motor (it says "motor" and I assume that means the axis motor).

Then remove the drain plug and repeat. So, do I just stop filling when new grease shows coming out of the drain port? I'm not sure how viscous the Molywhite lube is, or how I even know the 259cc's of grease is injected.
