motor's been running hot in our combine drive setup, what's the temp ceiling before we're asking for trouble?

Continuous operation should stay at or below 180°F. You've got some room up to 220°F for short intermittent spikes, but that's not a number you want to hang around near for long. Keeping it under that 180°F mark in day-to-day use is what protects the bearings and keeps the unit running through the season.
