Ford 3000 power steering issues

[scjumper]

I had a new power steering pump installed on my ford 3000 last week. The tractor steered good going straight with slight turns. Tried to make a complete turn around and it bent both the power steering cylinder shafts. I'm in the process of replacing both cylinders but can find no reason for the problem. Any suggestions. Thks

The pump you bought is probably wrong for your application with a relief valve setting that is too high.
You need a 650 psi relief. Pressure is adjustable by removing shims to lower the setting.
