Hydraulic Pump + AC Compressor = Useful Unit

Keep in mind he's only using the clutch, not the compressor. .... snip

I was making the point, that depending on the model, the clutch is designed to handle 5-15 HP, and to be engaged at speed. Your A/C compressor starts and stops when you are driving on the freeway. Although, there is little load when it first starts, since the pressures have equalized in the system since the last cycle. The load begins to build soon after the clutch as locked up.
