Do You Have Any Tips for Ensuring a Well-Tuned Hydraulic System?

We work on older, hydraulically powered, multi-axis systems, so we have a big interest in them not all converting entirely to electrically powered alternatives. By sharing a pump across many axes of motion, we believe we can keep our per-axis cost in line with any solution. We'd like to hear what tips readers have for ensuring a well-tuned hydraulic system with emphasis on the controls and the embedded sensors.
