    Ok, finally repaired the problem. All resolvers were changed. I rebuilt the the hoe valves. Found a problem with one of the pressure relief valves. One of the springs in the valve was broken on both ends, and the piston was stuck due to abnormal wear. The broken ends of the spring were not in...

    I'm going to work on the hoe valve today to make sure no debris blocking resolver. I checked all the front end loader resolvers already, it made zero difference. Thanks for responding, I will update when finished.

    Ok, completely rebuilt gp valves, and i am happy to say hydraulics are working fine now. i had the same problem with the hoe and the o'rings were missing on most of the resolver valves as well. Did this on the machine without removing entire gp valves, now that works great. I finally have a...

    I guess I'll track down the resolver. How many are there. I'm guessing 1 for each movement on the machine. Thanks
