Awhile back I got my brothers 1975ish Ford LGT 145 that sat out side for years dying a slow death.
I got it running well, but the hydro seems loud. I replaced the spin on remote filter and pony'd up and purchased genuine NHolland hydraulic fluid for replacement.
Its still loud. Its seems quieter when I run it floored, but when I feather back on the foot feet it is louder.
When the RPM is down and Im backing up or going fwd @ half speed it really groans.
Is this normal? Can it be better? Do some fluids quiet these things down? Are there adjustments or wearable items that make the loud?
