These are a little weak at times. I try not to turn steering wheel with out moving and that helps a lot. Try not to force it as the sector shaft tends to break with to much pressure.
Keep the front pivot points greased well as that helps. Also be mindful of heavy loads in the loader. If in a tight area that you need to turn the wheels, set load down turn wheel then pick back up.
The steering valve does have a pressure relief that is adjustable if needed but should not do that without a gauge. Not even sure what pressure it should be set. I did adjust mine down a little to help keep me from putting to much stress on the sector shaft.
Hope that helps. :thumbsup:
