Case 680g Steering Problem

Yea I took the pressure readings at the hoses that connect to the steering cylinders. So I think with those readings being good that leaves me with just the check valves for the secondary relief and if those are fine then the steering control valve?

Yes.

Alright I will try and dig into that this week. I will report back with my findings on the check valves before going any further. Thanks again for your help I really appreciate it.

I pulled both of the check valves and they are in good working order. I put them back in and still have the same problem with steering. I guess that leaves the steering control valve?

Perhaps.
Someone with experience in steering systems will need to help you.
I only know the basic operation of them.
If it is the motor I would be looking for a known to be working used one.

I was able to pull the steering control valve and open it up. I found a piece that keeps the main shaft centered was broken off and the broken piece was stuck in one of the gears. I was able to have a machinist repair it. I reinstalled it and steering is now fully operational! I appreciate all your help with troubleshooting this situation. If you are every in Wisconsin let me know, I owe you a few beers. Thanks again!

Thanks for posting your success.
I admire your stick with it attitude. It certainly paid off.
Be sure to change the hydraulic filter. Unfortunately it is inside then hydraulic tank.
