You are loading up the hydraulic pump when you do a full turn either left or right with the steering ram extending fully either way??, if this is the case, then one doesn't extend the ram fully, you can do the same thing with the loader controls, crowd the bucket and hold the lever in that position until the engine stalls, it is not meant to be done, you have to feel the limits of the steering and ram strokes.

It does happen winston, I have done it on 950 and 966 cat loaders unintentionally, same with the articulated steering on the machines, at idle this will stall the engine.

Raven6 you cannot shorten the main drag link, you would end up with a tight circle one way and a larger circle the other,-- can you disconnect the ram shaft end off of the drag link and then do a full right and left turn just to see if the ram shaft does travel enough both ways?, there is a possibility that the ram is too short.

What make of tractor is it?.

Here is a manual that covers your tractor, with regards the steering, only shows manual steering, shows the hydraulics a bit smudgy, but you should be able to work it out.

Over time, the tension of the pressure relief valve spring should ease off and the pressure should slacken a bit, I would be careful with adjusting the valves without a pressure gauge.

Usually power steering pressure is not full hydraulic pressure, but it is regulated by a flow divider which should be in the pressure line after the pump and the steering feed should come off of this divider.
