I bought a 6640 SL with a cab yesterday and have a few questions I could not find in the owners manual.
Does the power steering with off the main hydraulic system or is the another pump I have not found?
Can the steering cylinder be rebuild? I have found kits but not me tion of one on the New Holla d website.
Is the Hydraulic system open center or closed center.
Since this has the removal pto shaft to change out to a 1000 rpm do you still need to drain part of the rear end to change the shaft seal?
Thank your any input.
