I've got the '68 4020 LPG that has sat for 8 years. I've spent the last week getting it operating again.
I plowed my dirt road today and I noticed that the two lifting arms are not moving up the full travel they can move.
Both arms with no implement attached only move upward 1/2 way and stop. Always exactly at the same place. The cab lever is at the full up position.
The hydraulic pump is working and strains the engine as you'd expect. The oil tank is full and no leaks have been detected.
Why are the arms not moving fully upward? Lever not adjusted right? Hydraulic valve linkage not moving properly?
The manual does not go into this problem.
Any ideas?
