stt steering problem

[2729rdr]

I have a STT 61V-27KA that has a reversing problem on the left side. Some times it is hesitant or finally engages very slowley, or not at all. It's a problem sometimes turning left. I took it apart, and the only thing I saw out of order was the bearing insert in the back of the housing, which was loose but fit back in place very easily. Going forward is strong on both sides, and reverse is strong on the right, but the left reverse puts a small load on the engine, then drops off. Seems like I may have a bypass problem or some pressure valve is giving up too soon. Thanks for any suggestions--Ray

Sounds like either a sticky or broken shock valve.

Thanks ILENGINE --The only way I knew how to check them , was to switch them, which did not change how they operated. The left reverse was still almost non-functional.
This was my first time to use this site, and after I posted I realized I had posted in the wrong forum, instead of being in the scag forum, but I cant figure out how to change it---Sorry-- Thanks very much for your input----Ray
