I bought a Pettibone 88 this past summer. It's needs some work. One of the first issues I am tackling is the control valve for the front axle leveling. It's basically just 2 HYD cylinders that pivot the front axle so when lifting a load up high, you can level the load.
The issue is when I start the machine, the leveling tips to one side and stays there, deadheading and bogging down the engine. You can still move the machine but it ofc lacks power and stalls out easily because of the deadheading.
The tilt doesn't actuate at all no matter where you move the control lever, just stays to one side.
I removed the control valve and bought a seal kit for it so I could rebuilt it this winter.
I just got it apart, and I think the spool might be too warn to rebuild.
Here are some pictures:

It looks like in some spots on the spool, the chrome is warn all the way through.
First off, is the spool shot? Secondly, if it is, would this cause the deadheading issue I was experiencing?
