Hello!
We are working on a AC 5040.
Customer Complaint:
1 - No Pwr Steering
2 - 3 Point Hitch won't work
What we have done:
1 - Changed hydraulic fluid suction filter and all o-rings on suction tube/cap.
2 - Changed power steering fluid filter and o-rings in remote reservoir under hood.
3 - Resealed both hydraulic pumps.
4 - Visually inspected pressure relief valve.
5 - Visually inspected cylinder safety valve.
Where we are now:
1 - Power steering weak when tractor is parked, improves when tractor moving.
2 - 3 Point Hitch now lifts, BUT
a. With test weights, 3 point hitch oscillates up/down when tractor running and hitch control lever is in max lift height position.
b. With test weights, hitch slowly drops when tractor not running.
Important Note: if we adjust the draft control sensitivity regulating lever all the way to the "-", the oscillating is almost eliminated, but the hitch still slowly drops when tractor shut down. If we adjust the draft control sensitivity regulating lever all the way to the "+", the oscillating speeds up and is much worse, and the hitch still slowly drops when the tractor is shut down.
I feel like I'm close to solving this one, but need some help.
Anyone? I can get videos/pictures if necessary!
