Is it possible for one to bypass the 4 system, and operate the machine on Pilot Pressure?
Machine is early 90's....My father thinks its a 1993. Serial Number is 8818.
His machine is always out on jobs 50-75 miles from me. I do not have any pictures of the machine, hours or service history available at the moment. It was purchased from Casterline Diesel in Sweet Valley Pa by us 3 years ago. He's had issues with the offsetting boom hydraulics drifting and at times getting locked out to one side. The valve for it was replaced with a hand valve, the part from Komatsu was more than he was able and willing to dump into the machine. Still drifting and locking out from time to time.
Anyone ever removed the 4system and controlling the machine with just Pilot Pressure?
Anyone have an idea how to, plans of attack, time and cost estimates?
Appreciate the wisdom
