Hi all,
I recovered a used FANUC M-710iC/50 - R-J3iC cabinet from 2006, with approx 45k working hours.
Doing our regular service inspection, we discovered a suspicious grease leak from the upper arm, after J4, coming out from one of the upper arm screw holes. We sucked nearly over 1L of grease from the screw hole (see pictures for said holes) and it seems to be "empty" now.
I imagine this is not a regular place to discover grease, but according to different drawings i managed to get, I cannot figure out where it could be coming from. Moreover, I checked on 2 other M-710iC here in the shop, all of theses holes are supposed to be blind ...
Before I set off to disassemble the upper arm, I'd like to get your point of view on the matter.
Did you ever find grease in there? Is there a reason? What should I be expecting? Or has someone had 1L of grease to spare and stored it there for further use ...?
If you have any expercience to share with me, that would be great!
Thanks you all.
