L555 Hydraulic Issue

[cbsnowandyard]

After my guys ran my nh L555 out of fuel a while back I finally had time to get it going again. Now lies another issue. We had to winch it onto the trailer to get it back to the shop when it wasn't running (and batteries were dead at the time also). Now that its going it seems like i'm locked out due to the fact that each pedal won't move individually. Made sure it was full of fluid and can get the boom to move but when going up it will roll bucket back and only gets as high until the bucket rolls back to its stopping point. Any help would be appreciated especially due to the fact there is basically no one here in upstate ny that works on these. Not sure if anyone will need it or not but the serial number is 711236

The hydraulic controls are all mechanical so I would suspect the cross shaft going between the pedals is froze to the bushings in the boom pedal. The pedals should operate independently of each other.
Since the bucket circuit gets it's oil first the boom will raise until the bucket cylinder reaches the end of it's stroke. At that time the relief valve will open and all the hydraulic functions will stop.

What can i do to free the bushings up? I thought it was odd that they wouldn't move independantly of each other.

I should also probably mention that when i first got it running again that when I checked the hyd fluid it was very low and just barely reading on the stick until I filled it up.

Disconnect the rods. Lubricate around the bushings and then grab each pedal and work them in the oposite directions until they are free. If they do not move then you will need to remove them from the loader as an assembly so you can work on them.
