John Deere 555 steering problems

[axel7320]

Hello,
I have a John Deere 555 loader. The other day I was running it and noticed the right steering pedal was pulsating when applying pressure to the pedal. I also noticed when braking that track as the pedal pulsated the track would start and stop in sequence with the pulsation. I ran the machine a little longer and now there is no power going to that tract. I can brake the track and it will lockup but if I run into say a pile of dirt and put the machine under a load the right tract will not spin and now the pedal stopped pulsating. Anyone with any ideas? Thanks for any help.

the steering valve may be the culprit here .I think it is a slightly different system than the leaver steer system is although they can be difficult to bring back into adjustment either as paddle steer or leaver steer if the adjusting rod is either to long or short crazy things happen I know we had problems with one 550 A I think it was.Digitup.
