Needing some help/advice on hydraulic touch control lever on '52 8N. Hydraulics work but control level needs to be cycled from raised to lowered to get lift arms to raise, the position of the level is never the same when the arms are at the top. I was wondering, after looking at the exploded view in the parts catalog, if it could be the woodrift pin holding the the shaft to the lever is broken and the shaft just binding on whats left of the pin. I have taken the right side inspection plate off and found no leaks from the piston or the pressure relief valve. Trying to get an idea of what the problem could be before I start tearing things apart. Any help would be appreciated.
