Hi All,
I have a VN R-3. I am a half-fast machinist.
Thanks so much for your help.

ISSUE: The spindle is running a little hot.
WHAT I DID SO FAR: I took off the cap to see the rear bearing (in horiz position) and greased it through the zirk fitting in several places until new grease was visible all around. I then added the same amount of grease to the front bearing even though I couldn't see this bearing.
RESULT: Spindle still runs a little hot: About 70 degrees over room temp after 45 minutes at 1100 rpm.
(Manual says 70 degrees over room temp after running 1 hour at 1600 rpm.
QUESTION 1: I followed some other advice to use molykote grease. OK?
QUESTION 2: How can I know if the bearings are overgreased or undergreased? I assume both would cause it to run hot.
QUESTION 3: If I have to do this by looking at the bearings, can I look at the front bearing without having to pre-load the spindle bearings when I put it back together? The procedure for this in the manual looks complicated.
