New fluids and filter
Worked good for first 25 hours
MCV pump started to whine, then steering and TA stopped working, but brakes work fine
Replaced MCV pump with new 9 GPM hy-cap unit
Replaced all gaskets and seals on MCV
Installed new filter and everything worked
25 hours later, same problem
Overfilled by 4 gallons of hytran
Replaced all springs in MCV and safety valve 2000 PSI one at a time, no change
At less than 1000 RPMs, steering, brakes and TA work fine, installed gauge in lube port for low side pressure, all reads good, at under 1000 RPMs, no pressure over 1000 RPMs, except when brakes are pushed.
Questions:
Can it be the oil filter is plugged and I'm not getting any suction at higher RPMs?
Can the filter bypass be stuck, it seemed fine when I took it apart?
Tractor was stored outside 5 years prior to my acquiring, now has been stored inside. Have been getting a lot of water out of the hytran, could this be somehow involved in my issue?
Didn't connect high pressure gauge into safety valve. Didn't know what snubber was. Do I need one to do this check?
Any suggestions would be helpful.
