This morning I noticed that the oil temp for the Kobelco was high at ~150F (nominal is around 110-115F). Looking at the sight glass for the oil level, it was high compared to it's usual level during operation. (see attached, off line is when compressor is off, RUN is the level during operation)

Gerardo and I confirmed the oil pump was running and the oil line pressure was ok through the control panel. We then opened the ball valve for the coolant line which goes to the oil cooler. This very quickly dropped the oil temp back to nominal, and there was some tuning done to keep it at ~115F.

Gerardo then contacted the rep who replaced the oil pump on this unit a couple of weeks ago, and confirmed it was just a matter of adding more coolant flow to the oil cooler. The oil level at the sight glass then returned to it's nominal level. 

No issues since, but we will continue to monitor.
