John you are correct. But, GV recommends not engaging the unit below 45 mph. This is to keep the cone from slipping until sufficient pressure to engage the cone clutch is generated.



That contradicts the GV instructions which set the magic number at 20 MPH.

At any rate, logic would dictate that cone-clutch activation should coincide with maximum pump output pressure (at whatever speed that occurs)...my spitballing was theoretic.
